Major Oil Leak
My 88 YJ is leaking a lot of oil. Driving down the road or at a stop sign I can see a lot of smoke from the oil dripping onto the exhaust. From underneath it looks like it is coming from somewhere above, dripping onto the tranny near the oil pan and back on one of the skid plates, but cant quite tell where it is coming from, but there seems to be more oil on the passenger side... The oil sending unit looked fine and the valve cover seal doesn't look like it is leaking much, if anything at all. Does anyone know of anything that commonly leaks with these models. It is a completely stock 258 with a newly installed Weber. Thanks for reading!
FIRST i would clean it just like Joe Dillard said then I would make sure your pcv system is working and if its not theres your problem... but the damage could already be done and you would wind up having to replace almost every gasket...(oil pan, rear main, valve cover, pcv gromlets) I just had to do this to mine after i did the weber 3 months ago...

I will never pressure wash my motor, you may or most likely will do more damage. Buy about two to three cans of engine degrease spray and clean everything well. Rinse, Then inspect that everything is perfectly clean, reapply if needed, scrub heavy spots with a brush or rag, Rinse, Dry or let dry. Then drive about one mile, let it cool, then look or feel around. Find your leak.
Many folks do it all the time. A little common sense goes a long way.
This one has been pressure washed many a time.
This YJ (mine spends most of it`s time off road playing in the mud.
I use simple green on my engine. Let it sit for a few and wash off with a garden hose and it looks 100% cleaner. I've got a small oil leak too. I cleaned my CCV system and that seemed to help matters some.
also, check your oil sending unit, I've read that they are prone to break and leak.
""Leave it stock, it will live longer. Just understand that its never gonna be as fast as a minivan""
By the way from the looks of your setup, I doubt that you spend allot of time in the mud, also considering what you did to me in another thread http://www.jeepforum.com/forum/f12/y...t-mod-1077482/ and the names that you called me. I would prefer that you do not respond to my threads or replies in the future.
Too bad if you think I am pissing in your Cheerios. Your opinion differs from many others.
Please go away, You are the only person that acts this way on this Forum.
My alternator caught on fire.........Is this normal ?............
Now you are telling me how I wheel my Jeep. How do you know ?
To the OP.
On the passenger side, back of the block, just below the head is a tapped in plug. This plug used is to cover the machining of the block for the camshaft.
While not to common, this plug has been known to leak. Often times the cam will ever so slightly walk back and touch this plug. Ultimately wearing a hole in the plug and causing an oil leak as you describe. You might want to check this.
Thanks I will have a look see tomorrow if I get the time. It does seem like it's coming from somewhere back behind the head and maybe running down the block where I can't see anything, couldn't accomplish much today though...
Got my eye on you.....
Can we get this train wreck back on topic here.............
