PKRWD i need you help??

[Coupe50h]

alright, i didnt run codes yet, but last time i did the 98 didnt show up, it only did when i left my ect sensor out? now that is fixed i think.
btw koeoff test always pass with 11.

Today i was looking at the back of the intake, near where the pcv is, and i must have some sort of leak there? there is oily water there on the bellhousing, i stuck my hand back there with the motor runnnig and cant find any leaks? i pulled off my line that goes to the vac tree from the intake, and the motor died, that tells me i have a vacuum leak somewhere correct? probaly the hissing i hear on the backside of the intake, i'll pull it all back off if i have to, i used rtv on the ends, i remember being kinda short on rtv cuz i ran out, but i figured it was enough since it was a good size bead.

If the lower wasnt sealed on the end, what would leak out besides air?

pkrwd thanx alot.
