Rear china wall leak on the block is my guess.

Plenty of people have put in their 02 cents,here's mine If you just did the intake that's where I'd double and triple check. And the intake can leak oil and not leak vacuum. If you determine it's the rear seal on a 1pc seal 2wd it's no big deal at all . As for the stop leak the way I understand it it is an additive that makes rubber swell that's how it creates a seal but now you've compromised everything rubber that it touches,not how I'd do it . Get 2 long starter bolts take out 2 bell housing bolts and replace them with long starter bolts. Undue everything like you were going to pull the transmission, pry the drive shaft loose at the rearend, tape around the ujoint to keep the caps in place.slide the transmission back on the long bolts and you will have a window big enough to pull the flexplate out through the bottom. Then you can access your seal and end plate.

That would have been good info in post 1. Because we don't all know what everybody has and could Give bad information. Like assumed 2wd,but had I not written 2wd in my post you might have tried following my advice.
