The '90 I got just a few weeks ago has a small oil leak. I knew it was there, but had no idea I would have so much trouble finding for sure where it is coming from. Doesn't leak hardly enough to worry about. About 2 drops hit the floor after driving it a lot or a little. Can start the car and just move it in the shop and you get the 2 drops.
Drips from the passenger rear side of the oil pan. Seems to be coming from the rear of engine up high. Have checked all the normal stuff. Oil lines, senders, pan bolts, etc.
I can see a little fresh oil between the middle intake runners on the drivers side, but none towards the front or rear. Nor the passenger side.
Think it may be something under the plenum?
If it is, why do I get the same 2 drops no matter how long I run it?
I am open to suggestions.
Thanks Guys !!

a few of the header bolts tap into the oil galley and can can weep a bit

also look at the oil pressure sender which is a crimp plastic sensor on the front

oil pan little 7 mm bolts up front loosen up too


early oil hoses and less often the little dowdy washers under the cam cover bolts

overall the lt5 burns more oil than it leaks due to the breather box and lack of oil seals on the early motors

do a search on lt5 oil leaks and check it out!

Oil dye and a black light help identify source of leak.
