Oil pressure

So, now oil pressure drops down to 15 after warming up. Looks like there's a small leak from back of motor where bell housing bolts up, that would mean rear main right?

That would most likely be a rear main yes.

Trans/bell/clutch all have to come out to get to it. It's a pain in the *** to get out just because of how its in there. Common trick is to VERY CAREFULLY drill a few small holes in the seal and thread in some screws to get a grip on the thing. Once its out and clean, PVC pipe the same size as the rear seal and a block of wood is a good way to tap the new one in. Also if the clutch is getting up there now is the time to replace it as well as the pilot bearing and the TOB.

Guy I bought it from said t5 was rebuilt, but yet I have to do the rear shaft seal on it, and he said rear main was done at the same time. I don't know if that was true.

"the guy I bought it from said"... If I had a nickel for every time I heard that. Hell even my super clean 98 I got had some surprises for me but you have to expect that lol.

The T-5 will have nothing to do with an oil leak, if its leaking, it'll be trans fluid. You sure its oil leaking or is it Mercon? He probably did do the rear main seal, doesn't mean he or the person who did it did it right. Its very easy to not seat that seal all the way or think you did and still have it leak.

I hate main seals... $5 part and like 3 hours of labor on a lift with a friend if you are good. Don't even get me started on what shops quote to do this...

I have a pretty bad leak back there also. Replaced the main seal but it's actually coming from the oil pan after the old dirt was wiped off the back of the motor. I guess the dirt and grime was keeping it from leaking.

Yeah double and triple check its actually the main seal and not dripping down from above it or from the oil pan gasket.

But yeah I had a rear main seal seep on me that was brand new and 100% installed properly. They are just notorious leakers as was stated.
