ok theres a few things here


1. if your car is boosted lets say at 6lbs does the line going to the PCV valve see boost pressure or no???

ok cause heres the thing

97 gsr with JRSC kit only reading around -17 -18 on vac on boost gauge at idle after warm up, and gauge is also slow moving its not instant for some reason. The car idles fine not jumpy. and i cant find a leak?? have looked all over the place now what can i do???

and as for the PCV valve does it see that 6lbs of boost??? or no ???

 

???? what im saying is if the hose isnt tight around the PCV valve and air is getting there could it make the vacuum be lower?

 

bumpty bump bump

 

help?

 

The PCV valve will not see boost as it has a one way check valve preventing boost from entering.

Sounds like u have a small leak in your vac lines somewhere... I would use the process of elimination removing each vac source to each device in turn to see if your boost gauge registers a stronger vac.
