Ever chew any gum while you did oil changes?

a70eliminator No problems all good, took the 7 mile backway there, and then took the expressway home sustained 65MPH for about 5 mi. If it happens again you guys will be the first to know thanks for all your support!

Hair of the dog

So today it's -6 and mama needs to go out for some household staples, I'd rather her not mess with the 5.9 (her jeep) so mine's out there warming up now (I'm listening intentively as I type) It was really really slow to turn over in this cold but once it fired up the oil P. instantly up to first hash mark above 40, I'm taking the fresh clean 5w30 for about a 7 mile slow ride.

Scrubberguy So I'll tell a little story:

Back in High school a bud got a 1959 Impala hand me down from his Grand parents, nice car and originally set up for LP fuel. His GF's were very progressive, the LP conversion was pulled to put on the new Vega they bought and he got the Impala.

Car had 135K on it, a lot of miles for a 59 283, but it ran great most of the time. It did have one issue: it would idle smoothly and then suddenly run like crap for about a Minute back firing through either the intake or the exhaust, and then idle fine.

We went nuts checking points plugs timing but couldn't find a problem.

We then knocked around the idea the plastic cam gear might be missing a tooth or had huge chain strech allowing this issue.

The bud decided that swapping the chain was a good idea but since the motor had that many miles on it we would rebuild it.

Because we were way out in the sticks, Northern Cali was pretty forlorn in those days, he was going to have a mobile boring service do the engine rebore in the car!!

Our job was to strip the motor of everything but the crank so it would be ready when the Boring rig showed up.

drained th Oil pulled the tin, cam chain drive was bad but not that bad, and the bud was under the car pulling the pan.

As we attempted to pull the cam shaft a 4 inch long section of the cam fell out and hit him in the head!

Turned out the cam was broken and was a three piece set up, LOL! The cam would shift enough to allow timing issues and then "snap" back in place from the Vibration caused by the timing shift!

The engine over haul was a success, and was done long before the lump on his head went away, but taught me a lesson about moving parts I'll never forget.

In your case this pressure loss would drive me nuts! I honestly would pull the pan and the distributor, inspect the oil drive shaft and the internals of the oil pump and the drive area on the bottom of the distributor shaft.

Only then would I drive it again, if this failure happens at speed again you'll be doing a lot more than replacing an oil filter.

By the way the by pass on an oil fiter is to allow oil into the engine when the filter gets clogged and should not keep oil from being pumped to the bearings or valve train.

My opinion, which is worth exactly nothing, is you have another issue waiting to bite your back side.

Hope my story helps out.

a70eliminator Small world! I live off Hartville Rd on Waterloo. Work at the University.
We're at the golf course every 4th of July to watch the show, if I knew someone would be on that lake ice fishing, heard some great reports from others that have access.

Uniblurb Total white-out here too eliminator and can't even see the other side of the yard!

I know exactly where Kent is and my cousin went to KSU while living close by near Hartville, OH. He was my age and a rich kid while living in a big house right on Congress Lake. He had a small hydroplane with a large Merc outboard and boy did we get in some trouble up there! Along with my older brother the 3 of us drove the security guard who patrolled the area absolutely insane!

You may be correct about that, as in my readings I discovered that many believe that extreme cold can be a problem there. I don't see much downside to your changing to 5w-30w where you are. I have even considered it for running in SoCal. Right now I think I'm running 10-40w, which is probably a bit thick. I'll be dropping down in a "weight-class" next oil change.

I have no doubt that the information on the site is somehow skewed. There were all sorts of inconsistencies in it. What was the strangest was that, at least for that application, the Mopar filter AND the Wix/Napa didn't have a bypass valve. Apparently the budget version of the Napa/Wix may not, as there were no specifications regarding bypass-valve pressure settings for that part # on the Napa site. However, the Napa Gold 1085 did show as having a bypass-valve pressure setting in the spec's, indicating that, as you said, it does have a bypass-valve.

I've got no dog in this race. As I said, I have been mostly using Fram. However, I have had no real brand allegiance, as I wasn't familiar with those with and/or without bypass valves. In fact, in light of what I've learned in this thread, I probably will change over to what seem to be better choices, like Wix perhaps. I know that my local indy parts store sells Wix. Next oil change.

You guys stay warm and dry.

a70eliminator I'm leaning away from the oil filter being the culprit and believe it was the pressure regulator valve withing the oil pump itself. My theory, it was so cold that morning that when the engine started the oil pump (being of positive displacement) regulator valve had to have opened to relieve the access pressure of trying to pump molasis through a straw. I drove off and down the road the engine got hot, the oil thinned to the consitancy of milk and the regulator valve for whatever reason (probably piece of dirt) did not seal back off and caused a massive hemorage within the oil pan.
What fortifies my theory is that I checked the oil only seconds after shutting down the motor in my driveway and it was FULL which was disturbing to me, usually with the proper amount of oil the level would show very low on the dipstick 2 seconds after shut down because it takes 5 mins. or so for the top oil to cascade down into the pan. in my case ALL the oil already was in the pan with nothing upstairs.

Uniblurb I'm in Northern Ohio where right now it's a total white out, can't see the mailbox at the end of my driveway! Think I'll go out for a little spin and take my snatch-cord with me!

BTW: Here's a link to a rather loose comparison of oil filters. It's fairly obvious that it is a site that promotes Wix/Napa filters (Picture conveniently shows the Wix filter media rolled out to look longer than the Mopar, despite the Mopar being 3" longer.) , but it does contain some interesting tidbits. One of them is that the Mopar filter they tested supposedly does not contain a bypass valve. While the WIX doesn't have one either, I found it interesting. Does Mopar not think they are important? Or that they do more harm than good? Is this an oddball in the Mopar filter line?

Since I was maintaining four 4.0's at the same time, down to two 4.0's in my ZJ & XJ, I've always bought the NAPA gold 1085 oil filters in bulk/by the case. They have a pretty good bypass valve in them as can be seen in the below filter breakdown.

https://www.youtube.com/watch?v=YcJ0pp2pneY

The below video isn't saying much for the cheaper Fram oil filters where if the oil bypasses it travels over the filter material carrying dirt/crud into your engine. On the Fram premium oil filter they have a screen on the bottom but probably still better to have the bypass valve on top where the oil never travels over the filter material to begin with.

About the same thing here a70eliminator and I'll let you know how cold it really is as I haul a couple more wheel barrows of firewood into the house! I may even have to put my facemask on if I'm out there very long. Lol.

The National Weather Service in Wilmington has issued a wind
chill warning... which is in effect from 9 PM this evening to 9 am
EST Sunday. A Wind Chill Advisory has also been issued. This Wind
Chill Advisory is in effect from 9 am to 4 PM EST Sunday.

* Hazard types... cold wind chill readings.

* Wind chill readings... as low as 30 below.

* Impacts... the frigid conditions will be dangerous to those
venturing outside. Exposure may cause frostbite.

* Winds... northwest 20 to 30 mph with gusts up to 40 mph.

* Temperatures... 5 below to 10 below zero tonight.

* Timing... wind chills will drop below -10 late this afternoon and
early this evening... with wind chills rapidly falling to -25 and
below by mid evening.

a70eliminator Lucky you! Today we have a weather WARNING!
.. WIND CHILL WARNING REMAINS IN EFFECT UNTIL 7 PM EST SUNDAY...
* WIND CHILL... WILL DROP BELOW ZERO THIS AFTERNOON AND REACH 30 TO 45 BELOW OVERNIGHT.
A WIND CHILL WARNING IS ISSUED WHEN A STRONG WIND WILL COMBINE WITH COLD TEMPERATURES TO CREATE DANGEROUSLY COLD CONDITIONS FOR EXPOSED SKIN. THE WIND WILL MAKE IT FEEL LIKE IT IS 35 DEGREES BELOW ZERO OR COLDER FOR SEVERAL HOURS. THOSE PLANNING TO VENTURE OUTDOORS SHOULD USE COMMON SENSE AND DRESS WARMLY.

On top of that it's snowing and blowing like a blizzard right now. There's about 6 inches of snow on the ground, it's alot of fun to run the jeep through this stuff but the cold you can have!

Cbob4 Man am I glad I live in FL. We think it's ridiculously cold when it's 40*...
