I did a lower gasket and new upper intake manifold replacement and now it has a vacuum leak through the dipstick, runs rough. The pvc valve is clean. I'm lost any help would be great.
Thanks John

I believe that there are two O-rings on the PCV.... are they both on there?

That has caused many problems here before.

I'm with Crash on this one. Definitely examine the PCV system for all proper O-rings and a spring. Some people forget to do the rings and spring when they replace the PCV and it always ends up with crankcase vacuum.

I found a recent pic from another thread....



make sure both O-rings are there.

Thanks Ryan! Runs a lot better! still a little rough i need to replace the plug wires yet!

So, it was missing one of the O-rings then?


glad to hear that it runs better now

I have spent the last 2 weeks cleaning the whole upper end while waiting for parts to come through ebay " New upper intake $46.00 shipped" and put it back together oh so carefully I was so bummed when it ran like **** after i was done. things are looking a little better but she rattles a lot. Thanks guys! I'm sure i will be back she is an old one with a lot of miles on her! now i have two cooling lines from the transmission to replace as I'm sure you have seen a few times also, and maybe a thermostat that seems to be sticking. She was given to me so i working the bugs out. BTY. mine looks just like your * Ryan Gold rims and all. Fog lights sit lower and it has a pewter cloth int. is it maybe an SSE? no badging on the car to tell

Well I fixed the trans cooler line and filled the trans. so i could run the motor a little longer. she seems to rev up and has good power, but on the down side, it has this strange noise coming from under the intake area, revving down .But only the last few RPM'* kinda acts like a loose rod, but up higher. not real loud and hard. I'm thinking maybe the balance rod?
Thanks John

Well after this hearing this thing run I'm sure there is a lot of damage from the cooling leak. I'm done, it'* a PARTS CAR! Thanks for your help everyone.
Thanks John

Bummer.

How bad was the failure, and how long did things set before you got to fixing it?

Too late to go back now, obviously, but I'm curious how quickly the damage was done.
