Leaky Blazer 1991
I just got a 1991 blazer and it has a good bit of miles on it.It still runs great no noises turns over really quick and everything...But it leaks oil,more than I can handle.I think I found the problem but im not sure what it is.It is round and has spots for 3 hoses but has only 2 hoses going into it,its right next to the oil pan in between the oil pan and the transmission pan.I just got done scrubbing the under carriage so I could get a better look,while i was down there i tightened all the bolts...You wouldn't beleive all the looses bolts on the transmision pan and the oil pan..

Because you posted in the 1st Gen S-series section, I will assume that you have a 4.3L equiped S-series Blazer and not a full size.
You may have the typical leaking remote oil filter lines that is causing this leak. Pictures of the affected area would help greatly.

In the second picture, that is the oil line adapter. Looks like that is leaking pretty good.
You will need to pop off the aluminum cover to inspect inside the bellhousing to determine if the rear main seal is actually at fault. Does oil come out of the holes in the bottom of the flywheel cover? Or the back of the fly wheel cover?

Well I will take off that oil line adapter and go buy a new one?Would that do it or can i just get a seal?Or a clamp?....That hole you see in the flywheel cover the one that looks drilled no oil comes out of there.Oil might come out of the back of it,hard to tell when the transmission pan is up there..thanks for the help btw.
