This is my first post. I'm glad to be a part of the community!
Ive got a 88 xj laredo, 4.0 no mods, 215K miles. just basic maintenance. I've had this jeep a couple years, and its always left a couple drops on the driveway over night, but this has gotten steadily worse, to where im leaving noticible 5-6 spots after parking for more than a hour, and its time to fix it! Ive read that it could be the Rear Main Seal, but the oil is reshly wet, and surrounds the front of the oil pan more than the rear. it looks like its been sprayed, as if coming off the serp belt, which is dry, free of oil. the lower coolant hose, trans cooler lines, etc at the font of the engine are all coated, with fresh liquid oil, its not dried or old and slowy drips from there to the diff, axle, etc. its starting to get worse.
Is there a Front Main Seal that could be the culprit? or a oil pressure sensor i should be looking at? seems to be coming from the driver side front, but i'm at a loss as to where its coming from. any help would be appreciated, i hope this is enough info! thx

 

check timing chain cover... i always get holes in mine..

 

There is a front seal. Also check the front of the valve cover gasket.

 

X2, those will get holes in them. Especially with that many miles. HTH!!

 

If your gonna have the cover off, you may as well replace the timing chain too.

 

off topic but its not called leaking oil its called marking your territory

 

Funny, that's what the PO said to me.

 

haha yeah well i think the neighbors are gonna flip if I "mark my territory" on the street much longer. where at does the timing cover tend to start leaking? Does it call for a replacement or is it something i should try patching?

 

Another thing to check is the power steering pump. Mine drips a little and I plan to rebuild it this winter. The timing cover will need replacing now or very soon. I kept my old one and was going to weld the holes and retain for a spare.

 

I was leaking on my 93xj and the seal was bad on the OIL Pressure Sending unit (the little cylinder above the oil filter). $25 snap in part, stopped the drip.

To test it, i just wiped off all the oil that i could see. Got it nice and clean, then started the engine and watched that area for oil to start seeping out. After about 10 min, i could see a little oil start forming around that area.
