Knocking Sound After Seafoaming/Vibrating at High Speeds

HI Fellow Jeepers!! First user for me I am new at this whole jeep forum thing so if this topic has been discussed I am sorry and would love the link to read about it.

So I have a buddy who used seafoam on his Jeep and he said it makes a world of difference. It runs better, better gas mileage and so on. So I look into it and ok not a bad Idea. So I do the bottle 1/3 in the brake booster, 1/3 on the oil, the rest in the gas tank... When I did mine after seeing everyone else do it I was expecting a TON of white smoke... I got a little blue smoke some white smoke but nothing to the effect of seafoams website, or you tube. Also after do this I noticed that all of a sudden my engine has a knocking noise coming from what I can tell the lower part of the engine as you really don't hear it standing over the top of the engine, but you can while in it and it's only at idle. Also my idle is a little jumpy between 5-700 RPM at idle in park. NO knocking when I accelerate or while stopped at a light in drive. Anyone ever come across this?

Info on Jeep 03 Overland 4.7 HO 65,000 miles on it. after I heard the noise I changed the oil has been synthetic since I've owned it now for 3 years whatever the dealers synthetic was then it switched to pennzoil ultra 10W-30. I saved a ton and started doing them myself as the dealer was charging me cheap like 39 for an oil change instead of the 80+ whatever it is.. But the guy who I knew quit... Anyways. any help/thoughts would be appreciated.

Recent Service done by me: Replaced the High Pressure Power Steering Hose as it was leaking BAD. Changed the transfer case fluid (quadradrive NV247) and both front and rear Diff's by removing the covers and then cleaning it out and using the mopar suggested RTV.

I still get the binding noise on the transfer case when in tight turns is that something I can fix even tho I replaced the fluid or a new TC? and as far driving goes A LOT more smooth with new diff fluid and TC fluid. Just the binding noise on the tight turns and I know I am not supposed to be going this fast but sometimes I can't help it. at 85 MPH and above my car vibrates real bad at that cruising speed when I have my foot on the gas to maintain that speed I take it off. it goes away.

Next up is Spark plug change, but before I do I was wondering about the Knock. Sorry to ramble again I am a newbie I apologize if this has been covered before and i just didn't search long enough.

Thanks! :2thumbsup:

I brought my car into a well known shop for a oil change. About 2 hrs later they said my car was done but the serptine belt was cracked and old so they just replaced it and it was close to $60. I told them that it was odd that a belt with less than 500 miles on it was worn out and old. I pulled out the receipt from my wallet showing the new belt that was just put on and paid for my oil change and free belt. Never went back again.

I now have a very trusted mechanic who does the stuff I'm not comfortable with or don't have the time. He either gets the parts or I supply them. He charged me $200 to pull the dash to change the heater core and blend doors and refilled the AC system.
Well I would have told them..... I didn't authorize you to change the belt. Lets see the old one.
And I am not paying you.
No shop dealer or private can change parts without your authorization.
You guys can sit here and bash on dealerships as much as you want, but you really have no concept on the inner workings(no offense) of one.
How labor times are determined, and its not by the dealer. And.....all shops dealer and private use the same labor times.
You pay an electrician/plumber/contractor/dr/dentist for his time, but you don't want to pay a dealer tech for his time.
And yes a dealer does a safety inspection for two reasons.....
1. To check your vehicle over for recommended services that may be due.
2. To cover our *** for liability. If I do a repair on a vehicle lets say a water pump and you drive down the road and hit a tree because your brakes are metal to metal. Guess who you turn around and sue.... The dealership because we didn't inspect your vehicle and tell you there was a problem with your brakes.
I can debate all of this to no end, so If you guys want to start a separate thread please do so.

Wrong!

1st, I have worked at dealerships.

2nd, you said you get paid nothing for checking all the bogus issues yet a shop charges a diagnostic fee.

3rd, shops use unfair and pushed up labor books that are set by unions. Why do you think the manufacture does not pay for warranty work by the labor book but there own knowing time scale for the time the service takes.

You can try to suger coat it all you want, and I suggest that you don't tell people what they know or have done, there are people on here that have forgot more then you know.
 
#44 ·
Actually my friend you are wrong.
1. We don't get paid anything to look over your whole vehicle, they are called MPI's Multipoint inspection. Its on the RO but we as techs get nothing fo4 it.
2. Uhhh what? Pushed up times? We use what the manufacture says which is about half of what you need, warrantee time sucks. If it says a water pump takes an hour to do, double it. If its not warrantee time is not used, we use AllData, just like every other shop in the world.
3. Diag time is what it is. Time for us to figure out what you cant. You come in and say your jeep is making this sound, what are we suppose to do not get paid to figure out what's wrong?

Come on, use your head.
 
#46 ·
explain to me how we get commission on sales? Did the dealer say that just in case it takes longer? We tell customers all the time it might take longer then it should just in case. We get paid what the book says. We have a new reflash (M38) it says it takes .2 (what we get paid for) it actually take way longer then that to do. It works both ways.

psssst the recall you are talking about, I just looked it up. There is no additional time for tow packages. Or nowhwhere near the time you say. I wanna see you replace a fuel pup module in less the 1.3...Where are you getting these bull**** times?

SYMPTOM/CONDITION:
The customer may experience a longer than normal engine cranking time prior
to engine start. This condition may be caused by fuel pressure loss due to
a worn sealing ring within the fuel module.
NOTE: QUALITY ANALYSIS HAS REVEALED THAT A WORN SEALING RING IS THE
PRIMARY REASON WHY THE FUEL MODULE IS REPLACED FOR FUEL PRESSURE
LEAK DOWN. IT IS RECOMMENDED THAT THE SEALING RING BE REPLACED
BEFORE A FUEL MODULE ASSEMBLY REPLACEMENT IS ATTEMPTED
Repair fuel pump module 1.3 Hrs.

Here is the BS clam. Btw I knocked it out in 3hours with out a lift in my garage.

This is some good info as well.

http://www.ehow.com/info_8733856_do-dealer-mechanics-paid-hour.html

Don't forget I was in that industry and didn't agree with how any of the practices take place. Anywhere I go to buy a part or service for anything first thing I ask is "are your employees salary hourly or commission" and make my judgment from there if I want to be there customer. I understand if I was in a pinch and needed $$$ to feed my family I would up sale things too, but do to the fact that it is getting out of hand is just appalling.
 
#48 ·
that's still optional equipment. A different punch and time altogether. You must have been a horrible tech if you don't know this stuff...What does buying parts have to do with if the tech is hourly?

"I understand if I was in a pinch and needed $$$ to feed my family I would up sale things too, but do to the fact that it is getting out of hand is just appalling."
Wait so if you bring your car in and lets say have your tires done. Before I take the wheels of I shake down the front end and find a loose tie rod and your brakes are below 2/32s. Is that you just thinking that we are trying to up sell you? :lol:
We wright that down on the RO to cover our *** in case you go off a cliff and to see if you want to actually fix your vehicle. Nobody is forcing you to do it. Im guessing you either got fired as being a tech o had a bad experience...

I had quit after 2 years if you must know. I'm not blaming you as a mechanic but the actual dealers. Commission or peace work is a horrible way to pay someone as it almost always leads up selling products and work or shotty work.

As for how long it takes mechanic to perform the service needs to be revised there are so many services in the labor book that have been upped do to letters and petitions sent in asking and stating that it is an unfair amount of time because the younger generation wants to be lazier and take there time.

Now my problem with the dealerships is on top of what the mechanic makes for the time it takes they up the rate by more then double what they pay the mechanic so they can make a good cut too and to top that off they up the price of parts to make even more. Dealers need to be regulated like credit cards.

The last issue I had and set me off was because I had just changed the front and rear diffs and New spark plugs had the wife take it in for an oil change do to me being out of town for awhile and they tell her all those need to be performed ASAP, so this is showing that because it wasn't in there system that it had been preformed and that it was needed yet it was listed on there MPI that they had preformed and supposedly inspected.

Being in the business for 2 years hardly gives much merit to argue with.

"Now my problem with the dealerships is on top of what the mechanic makes for the time it takes they up the rate by more then double what they pay the mechanic so they can make a good cut too and to top that off they up the price of parts to make even more.

what the hell are you talking about? Are you talking about flat rate? Like if the books say 1 hour and it takes me half that I should only .5? How about if it takes 1 hour and it takes me 2? What then? You gonna pay the difference? I didn't think so. As far as the parts go, its the same where ever you get parts, how are going to make moneyif you sell it for list price? You gotta think about these things.

"he last issue I had and set me off was because I had just changed the front and rear diffs and New spark plugs had the wife take it in for an oil change do to me being out of town for awhile and they tell her all those need to be performed ASAP, so this is showing that because it wasn't in there system that it had been preformed and that it was needed yet it was listed on there MPI that they had preformed and supposedly inspected. "

That makes no sense at all. The tech fills out the MPI before the work is performed. Im guessing that your jeep was due to these things from millage. That's your wifes fault for not knowing what was done on the truck. That's your fault not the dealers. Did you ask to see what the plugs and fluid look like?

anything else you wanna know what you did wrong?

She is the one that called them out on it and asked to show why it needed to performed, and why in the F*** is it the customers job to say no it doesn't need to be performed then state why. It was the Tech the performed the inspection not the service rep, now if my wife was unknowing to things that have been replaced or what was really in need of services you think that they would have came out and said "oh hey mam everything looks new so we are not going to perform the services that we already told you needed to be done based off our inspection the first time." Lmfao, no they would not have!

As far as charge, the dealers near me charge $95 an hour, are you going to say that is what the mechanic gets paid, lmfao! Mechanics don't even see half that.

you guys are still on about this?

there ARE dishonest dealerships and service centers out there... and there ARE dishonest mechanics out there.
yes, there ARE dishonest customers as well.
we live in a country of THIEVES. i mean hell, WE STOLE THE LAND WE LIVE ON!!
you think everyones going to be honest? come on.

ive been told by a VERY well respected mechanic in my hometown, that my jettas transmission was clunky and shifting hard because of a bad ball joint...

if you are a tech, and never robbed a customer blind, then you have no reason to defend yourself. but at least admit that other techs DO rob customers.
ive seen it with my own eyes, ive heard from friends who are techs ADMITTING to doing it, and ive BEEN robbed.



christ people...

I just assumed that she said yes because you keep bringing it up.. Where have I been proven wrong? You keep making outrageous dumb claims, but you know nothing on how things actually work and I tell you facts, not theory's like yourself.
Again, where do you think that 95 dollar labor fee goes, im intrigued. Also explain to me how other shops work that are different from a dealership. Because ive worked in both. Again im interested on how you think things work.

First you said that there is no pay increase with how much work is performed, in lamen terms. Showed you with a link.

Then how much man hours to perform a certain tsb, showed you a picture.

Then saying it is a service sales rep to say what services are needed when it was infact written down on the so called MPI sheet by the tech performing the service.

Luckily they were called out on these and couldn't back it. The thing that gets me is how often this is pulled off on people that are unknowing and obvious to when and what needs to be done. The dealer I was referring to was reported to a local news station and was cought trying to scam once again as well as 8 other dealers and service centers. I will continue to report place like this.

To the OP, you should tell the dealer you have a knock, that you dumped magic in a can thru the PB booster line and ask them their opinion.

I would guess they will listen and if they think you damaged the engine, they will do a compression or leak down test. They can give you the results, If they think it is the Purge solenoid or leak exhaust manifold they will probably tell you.

I wrench most of my own stuff but know a couple techs at local CDJ store, they dont work flat rate, but they are honest and work damn hard for their money, I wouldnt want to work on most of the crap that comes into their store. people mostly just ruin their cars because they dont do squat for preventative maintenance.

XtremZJ

I see your in NH, what store you work at, I am in Maine.

Why dont you start a thread and tell us some of the horror stories of idiot customers, it would be entertaining reading. other techs could chime in. I know some on these forums think every dealer is out to steal the money.
The reality is, if you dont want to do the work yourself, you pay.

Haha I might do that.

First you said that there is no pay increase with how much work is performed, in lamen terms. Showed you with a link.
I didn't click link. Again you cant have a pay increase, Chrysler will back flag it
Then how much man hours to perform a certain tsb, showed you a picture.
which was wrong you said it was x amount of hours and it wasn't.
Then saying it is a service sales rep to say what services are needed when it was infact written down on the so called MPI sheet by the tech performing the service.again the tech writes down what it needs for mileage, the service writer sells it

Luckily they were called out on these and couldn't back it. The thing that gets me is how often this is pulled off on people that are unknowing and obvious to when and what needs to be done. The dealer I was referring to was reported to a local news station and was cought trying to scam once again as well as 8 other dealers and service centers. I will continue to report place like this.
I wanna see this link of the news.

Again I wanna know how you think the services labor dollar amount works and how other shops do it different. You keep avoiding this question. :laugh:
 
#58 ·
when i worked as a salesmen for a short time, the general manager himself told me, they dont care if the customer leaves happy with the car they want, its about money.

some dealerships are out to take your money
 
#59 ·
And that is why I quit, I can not live knowing that I rip people off to live, I guess some people can sleep at night knowing they do.
 
#60 ·
i got fired, because i didnt learn how to rip people off fast enough. i was honest and polite with my customers, and management didnt like it.

but the fact remains, some dealerships rob, some dont.
some mechanics rob, some dont.
some customers lie, some dont
 
#66 ·
its not shortcuts or lies. Its knowing the about the vehicle. A l27 recall pays .6 I can do it in .4

An alignment pays me 1.4
I can do a alignment on a jeep in .5

2 tie rods and a brake job with alignment? 4.4hrs
I can do it in I bet 1.5 if I don't have to wait for parts and all goes smooth.
 
#67 ·
your missing what im saying.
if someone can take 5 minutes off a job by not changing an oil filter, skip greasing anything, and skip torquing anything... they take a good couple minutes off a job and can then move on to another, and do the same thing to the next poor bastard.
how fair is that to the unsuspecting customer?

when i talk about getting away with lies, i men telling a customer somethign was performed when it wasnt.
and if a customer wants an oil change done with only 1,000 miles on the oil, and a dishonest tech knows this isnt necessary, he could take the job, sign off on it and not even touch the vehicle while he does another job.

my point is, if a dishonest tech knows he can cut a job time down in half by taking dishonest shortcuts, he stands to make much more money and the customer never knows.
 
#70 ·
I guess anything Is possible. lol
 
#72 ·
im not saying hes guilty of anything, because im sure hes not.

but i am suggesting hes just not seeing the truth.
if hes NEVER seen it happen, then he has no reason to believe it, but remember bro, many of us HAVE seen it. im sure some here have done it themselves
 
#77 ·
So if you build a car that only costs 5k and the manufacture sells it for 10k, should he get a check for the difference?:laugh::laugh:
 
#76 ·
Why don't you answer the questions? You are quick to jump, but have no answers to anything ive asked.
 
#79 ·
Usually when it takes longer then expected you know its going to so you tell the customer, not let them wait in the waiting room not knowing whats going on.

when I diag a car and we say its going to be an hour and we cant figure it out in that hour. Who pays for the extended time?

EDIT: 500 posts woop
 
#80 ·
a diag can never truly be guarenteed to take a certain amount of time unless its simple and the customer can accurately describe whats going on.
so ill give you the diag.

but a simple service, shouldnt take double the time, or even more. ya **** happens, but running into a corroded nut or stripped bolt... shouldnt make the time go up much. and should be quickly remedied.


how about this for an example.
you go to the grocery store and end up with a gallon of sour milk.
you want some compensation from the store for selling you sour milk right?

just saying

#81 ·
You just proved my point. That's exactly how plumbers, electrician or anyone in the trade works. How do you think people make money?

You provided a link that has nothing to do with what you said on where the money goes, just on how much techs make.. I make $30.75 an hour, that link was quite low You said you couldn't figure out why 95 dollar labor times were so high if the tech "wasn't making half of that". So go on answer my questions for the 4th now 5th time?

From reading your other posts on other threads I can safely assume you don't really know what your talking about on anything. The sad part is that im only two years older then you lol
 
#84 ·
oh, heres a good example.
i drive a taxi, when someone calls and asks "how much will portsmouth to dover cost?"
ill give them a rough quote "probably about 30-35"

if i get them there for $25, i dont charge them 30.
 
#85 ·
That's the difference between our jobs, I can make 20hrs by working 8. But again that how these trade services work. You are paying for that person knowledge tools and services, again plumber says it takes 1hr and it takes two, the customer makes out, if the plumber takes half hour then he makes out. Its a win/win lose/lose for everyone.
 
#86 ·
neat! I couldn't tell from your grammar hat you passed the 8th grade....
Don't blame me you had to do child labor because your family couldn't afford to keep you, I too put myself through college and actually graduated from high school with my associates degree in Biotechnology and then got my degree in business, im no dumb grease monkey. So when you were a teenager you worked a dealership and now you know the in and outs of it bwhahahah.. what did you do? Change oil?

Pssst.... still haven't answered my questions though!

GUYS WOW!!!! Ok didn't mean for this to go this far!!! I was just upset that a seafoam rep came to my trade school, showed and demo'd the product gave out free bottles of the stuff since i had an older car, hey there might be build up I don't know. I haven't preformed the leak down test or the compression test yet. I am planning on doing that this week if I can. But when some sales rep from seafoam does this presentation and then shows you how to do it and I followed him exactly and I did not mean to pour the last of the bottle in thru the vacuum lines via the brake booster to fast when the bottle was almost empty, a mistake on my part. And again I am learned the basis of how to work on cars and engines etc.... I have been in school for 3 months I should have known better.. So I am not going to go to the dealer and say hey I messed up and put an additive in my car and now it's making knocking noise. I am going to Diag it myself with the help of my instructor.

As far as money and the car biz goes, I love cars sold them from 07-2011 I hated it so bad towards the end I couldn't deal with it anymore... people fighting over $15 on a commission slip and this person stole my customer and etc etc.. and the hours... I don't remember being at my house very much.. 60 + hour work weeks.. "steeling" from a customer when they buy a car... Well ok I get everyones point but, car dealers are not charity's nor are grocery stores or places like macy's or any business that sells something, there is mark up in EVERYTHING... Everyone hates on the car dealers cause well its pretty bad... and as far as people complaining that a tech is there to rip you off, A. thats your fault, B well he's doing his job based off the miles on the car. and what the manufacture says to do... So really think about it, commission, flat rate, hourly.. How do they get paid??? By the profit of the product they are selling... no one realizes that everything including a a box of cookies has profit built into it...

If you don't like it. Move to the middle of the woods and live off the land and then see how things are...

Ya those have traded a bunch of hands lol.

It's funny tho the rest of the dealer is great and wonderful, the wife or I walk in I'm always greeted told " HI Mr. And Mrs. (put name here). But when I deal with these problems I always get I'm sorry we'll take care of it, I'm just getting burnt out on having to go through the hassle. I always said its not northglen in the back of my head.

The wife was trying to surprise me by having it done before I had came back into town and having to do it my self.

Bitter but only person someone can trust these days seem to be there self.

If it wasn't for high priced shops JF wouldn't be here.
