its not a tick. its just the initial loud sound that sounds like a growl as if it has an exhaust. EVERY vehicle ive ever owned has done this. its more noticeable if it has an exhaust and is a v8. super loud at start up then tones down. I bought it used so no idea

BUT METAL ON METAL = TICKS!

Thats not good even on a old motor imo.

Did you break in the engine like you were suppose to?

the only thing chrystler has goin for them is the wrangler and the cummins. ive got several buddies with newer chevy/gmc 1500/2500, 2010+ ram 1500/2500/3500, and f150/250/350 2005+ and ive owned 3 2007+ f150s. the rams are junk and still get **** fuel economy with that 4cyl shutoff crap, the chevys blow in that dept not to mention expensive for what you get, ford has best fuel economy without that cylinder shutoff stuff.

for has more room and is nicer on the interior even in an XLT. their diesels have more usable power factory and better fuel economy before and after emission control deletes (but got 18mpg on the hwy in a 2011 f350 dually crew cab 4x4 and 21-22 after deletes)

The New Pentastar engine is genius imo....My plan is to ride with the Wrangler for a few more yrs to graduate to the Cherokee SRT Hemi! I like new tech, with the pentastar,but American muscle is where my heart is.

Peace.

Haha! No thanks. I've had enough GM power train drama to last a lifetime. Although... You may have a good point. My last v8 Chevy may have been a pinging piston slapping underpowered boat anchor, but at least it never had to ride on a tow truck.
if its a coil pack" BUT that is hardly the case 99%. These are KNOWN issues with these engines. The fire order is even one side odd the other. Mill code for miss fire on both sides. I would bet that both heads have burnt valves.

Sure in Jeep Jk as the newer ones wont fit the 2D. This is a old Mercedes design. that is well past being modern.

6L8o has a lower gear than the w580 and it is supported for tunes and huge after market.. The w580 no ability to tune still and from what i have read, wont. You can not even buy a atlas 4s as there is no way to keep it from limp mode.

But hey cast iron hemi......canbus from h3ll......or a sweet ls with a stand alone system?

Like i have said before. caste in exhaust manifold? never was good idea back in the day and it is not today. My 2cents.


Lemon? They still can not seem to keep enough heads in stock what does that tell you? How many years of testing did they claim? then in a short time with NO real answers still? They fixed it? sounds like a Beta test from 013 up and the 011(this motor was in use BEFORE jk's) then it was harmonic balance issues. was alpha test. we are the guinea pigs.

Not to knock but, they can keep the 285hp hell it don't make that until you are hanging the rings out the tail pipe anyway. I will hold onto a engine that can actually stay in one piece more than 36k miles. To me if they have been developing this engine since 2010 or what ever year you would think they have it figured out. Heck my 3.8L that was put together by little Mexico went almost 70,000 on a spun rod bearing could have gone a little longer but, didn't want to destroy the block. I bet the 3.6L would run about 5 miles on a spun bearing before blowing up. For those who say the 3.8L isn't any good are wrong because no engine can be great when the rings are put in upside down or the machine work is done with 10 dollar equipment. If you get a 3.8L that wasn't made in Mexico its solid. My current engine has 20k and runs strong and super smooth and has plenty of power for what a Jeep needs even with the 3.73 gears. I just don't see all the fuss for how great the 3.6L is.

If I was looking at a used Wrangler with the 3.8L how can I determine if the engine was made in Mexico or elsewhere? Where else were they made? Thanks.

AFAIK the link between oil consumption and the Mexico factory was never more than rumor. That being said there is a code cast into the blocks. I've forgotten what the code is, maybe someone will chime in.

I'd suggest a compression/leak down test if you're worried about the rings.

Most were made in Trenton but, late 07 and early 08s were made in Mexico to cut costs. Thats why some 3.8's get a bad name. Either rings were installed upside down leading to oil consumption or you had poor machine work that led to engine failure usually rod bearings. Aside from that 3.8s are known to go 250k easy. Think of how many minivans are running around getting abused with 200k or more? I know the dealership I use to work at had one with 235k ran hard like a mofo with little maintenance. Its truly the best V6 Chrysler has ever made to date. It might not have the most horsepower or torque but, its very simple and reliable. Its the 4.0L just a little more modern.

Think about it this way. The space shuttle program was successful and set the standard for safety and reliability. Far exceeding what we would expect from Jeep and our earth roaming machines.

They had 135 launches and 133 landings. 99+% success rate.

In 2012 Jeep made over 700,000 wranglers. The same failure rate would mean over 10,000 engines blow up that year.

I don't think 10,000 engines blew up or there would be a lynch mob.

So Jeep is doing better than NASA.

700,000 Wranglers in one year? Nah.

Combined between Canada and USA, there were only 161k sold. I HIGHLY doubt there were 539k of them sitting on lots at the end of the year.

Jeep, combined, didn't sell 500k vehicles.

FYI


Last year was good to Jeep. Chrysler has announced its trail-rated brand set an all-time global sales record in 2012 by moving 701,626 units. That number easily surpasses the previous record set in 1999 when Jeep sold 675,494 models. All told, the brand saw a 19-percent sales increase worldwide over 2011, and much of that swell can be traced directly to the Wrangler. While the Grand Cherokee led Jeep sales, the Wrangler posted record numbers both globally and within the US, moving 194,142 and 141,669 units in each market, respectively.

Meanwhile, the Compass beat its previous global sales record with 103,321 units rolling off of dealer lots. In the US, Jeep sold 62,010 Patriot units, breaking that model's previous record as well. Jeep's impressive performance in 2012 marks the second year in a row the brand has seen double-digit percentage sales increases. Check out the full press release below.

I have not seen so many of one make on the roads since the famous Ford pinto..................lol The Wrangler has to be the most sought after vehicle out there imo.

Btw..the 3.8 was a great engine as far as longevity is concerned. My Daughter has flat out abused her 2011 Wrangler and its still just as tight as a new one at 44k miles.I started using full syn oil after 30 k mile break in , purrs!

My mistake on the stats. But either way its easy to forget how many are out there and how life on these forums can make mountains out of mole hills.

My 3.8 is at 76k with just routine maintenance and no real repairs. I just cleaned the TB and it got me about 1.5 to 2 mpg, and I can use the 91 octane tune with no pinging. Previously I was on tow tune to avoid pinging.

I have a 3.6 in my work van and drive about 25k per year. I'll find out pretty quick if its going to last.
