!!!!

First 10w30 in my car which specs 5w-20, now 20w-50 in a Jeep 4.0 that specs 10w30/5w30.

The project rotbox Cherokee has sprung more leaks! Once the oil pump plugged and we cleaned it, it started spraying from the oil pressure sensor. Fixed that and now it's leaking from elsewhere NOT rear main seal.

Looks to be some from the headgasket, oil filter housing assy and distributor.

So, 20w-50 it is. This is only temporary. The lifters do not like it! What was a quiet engine (even after it ran dry!) has some lifter tick until it heats up.

And, being a Renix 4.0, it does not affect the 45 second crank time!

I think next I'm going to buy 25w-60.


On yeah, it's being run with a OCOD.
 
you should step up to 75w90 gear oil if the leak persists.
Don't worry, you can get it at Walmart too

He would have to make it 140 weight.....90 weight only correlates to somewhere aroung 40-50 motor oil.

75w-90 would be as thick as this. But, I *DO* have 85w140 in the back of my 2000 Cherokee for now! Apparently that is what I'm supposed to use for offroad and towing ... and that's what my 2000 is used for.

The camchain is pretty stretched on it. I imagine something heavier than 20w-50 would put too much stress on the oil pump and cam chain and cause it to jump.

No. Was due for an oil change and had some cheap Peak 10w30. The Pennzoil High mileage stopped the leak on my 2000 so that is what I am going to continue to use, but even at that, not due for an oil change on my 2000 Cherokee for 11 months.

Ah! You know what I'm talkin' about! My friend keeps getting confused by the thing because his other vehicles and mine fire off on the 3rd or 4th revolution of the starter. Not this!

Totally kidding about that. Once we change the head gasket and all the other stuff that is causing this thing to be the Exxon-Valdez, it's going back to 10w30 or 5w30.

It's sad that this 25 year old 200000 mile engine is quieter than my 15 year old engine with 130,000 miles ... and this one has been starved of oil!

Does your Jeep have the inline engine? I knew someone who had a Cherokee with the inline and it was SMOOTH!!

Yup. They both do. The 90 idles very smooth when it's not having EGR issues and is whisper quiet when not using 20w-50. My 2000 is a bit chattery (some sort of unidentified knock) and is a little rough due to having [censored] injectors.
 
Heck, if ya' were closer I would give you some SAE 50&60 VR1 oil and some Valvoljne MaxLife 20w50 SL and earlier oil for the "rot box project Jeep"

SAE30 by quite a long margin.

Not sure, but a conventional 20w50 has a VI in the 120s, so I'd say line ball.

All things being equal, I'd say the Delo 15W30.

It's an oddball filter. ONLY auto zone stocks a filter for this vehicle and it the OCOD.

Founder the leaks. Replaced oil filter oring and distributor oring.

That should take care of the hemorrhaging
