What's up with my boost?

[jefferson]

I recently had the exhaust off the car to reseal the oil/coolant distribution plate on the back of the passenger head. I didn't remove the drivers side manifold, just all the other pieces. My boost before always went straight to .05mpa and now it goes to .04 and then slowly rises to .05 as the rpm increases. If there is an exhaust leak I can't hear it. Ideas please.

Have you checked all the vacuum/boost lines? Did you remove any of the intake piping to get access to the rear part of the head?

Did you put in new exhaust gaskets or reuse the old ones?

The car runs too good and idles fine for there to be a vacuum leak from my past experience. I did remove the turbo to tb piping. I have had it off numerous times before with no issues. Worth looking at again I guess.

I did replace the gaskets on the up pipe with new as they were oem only and I really didn't want to mess with the down pipe etc to fix a leak. The crossover and passenger side manifold were reused. I knew I could get those at the local parts store. I didn't remove the drivers side manifold. I would think if any were leaking I would hear it. Thanks Josh.

I'd probably suggest starting with the crossover gaskets. In my experience sometimes the multi-layer steel gaskets can be kind of finicky.
