4.0 oil leak solutions

[OWEN]

Changed the oil on my 95 Wrangler the other day. Seems like oil is everywhere. What are you guys doing to keep these engines dry. if you say V8 swap, I already have plans in the near future, but for the coming year what are a few solutions to cleaning this engine up. I was thinking oil pan gasket and valve cover gasket... any others?

use a funnel in all seriousness that would be a good place to start. cant tell where its coming from?

I have done tons of valve cover gaskets, a lot of the time I find the oil filter adapter leaking also. Those seem to be the 2 biggest I have encountered.

valve cover gasket, oil pressure sender, and rear main seal have been my problem spots

oh yeah thats what i wanted to mention, oil pressure sender. ive changed my oil before and nicked it a tiny bit with the oil filter wrench and it was just enough not to spray everywhere, but i lost about 1.5 quarts in 2 weeks i changed my oil, and the sender and i was good to go.

lol, I do use one ya jackwagon. Some of what I put in ever so carefully comes out over time. Not enough to raise much concern (1-1.5 qts per oil change) or even leave an oil spot. The engine looks as though the valve cover gasket maybe leaking and the oil just cascades down onto everything, or other stuff is leaing also. Basically my plan was to order some gaskets for the fairly easy/problimatic stuff, and put them in next time I do an oil change on a warm weekend and hope it cleans it up.

Sounds good, did not know about the oil pressure sender I will look at that. Thanks for the replies

I love my oil leaks, slows down the rotting of my frame. My rear main leaks, quarter size puddle after a few days, all its been doing is sitting lately too. Other then that my 95 is pretty tight.

If you let it leak enough...eventually it will stop.

I'm no help, I know.

That's my theory with my diffs

ya jackwagon

[kracker]

when i had my yj...it used to leak out real bad ...then i changed the valve cover gasket and started using 10w30 and lucas additve and it never leaked again...

it's a bitch to get right but usually people don't torque down the two rear bolts on the valve cover and it will seep out there making you think it's a rear main seal

If it is leaking that much then it should be easy to figure out where it is coming from.

If you are doing an oil pan gasket do the rear main at the same time, only an extra 15min from there.

But I don't understand why couldn't find the leak? Brake clean air hose clean it off and drive it. Could be more than one spot.

Also check the PCV vent is not clogged. just blow air through it you will brake it if you try to take it off.

And buy the good gaskets not the stupid cork ones they never last

X2 on buying the good gaskets.. Also Id bet the orings are shot on your oil filter adapter which can be a PITA to get off... Its a 4.0 its probably going to keep leaking no matter what you do...
