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???? could that cause the gauge to be slow moving?

 

please?

 

ttt

 

help

 

Your question is real hard to follow. PCV will not see any boost on a JRSC integra. The PCV hose is placed before the blower so it will only see vacuum. And f it did I don't see how it would really affect the way your boost gauge reads. Sounds like you have a bad gauge to me.

 

ok so the PCV only sees vacuum correct. so if lets say my hose going to the PCV isnt on all the way and air is getting in it would make the gauge possibly read -17 and not -20 cause its not sealed correct?? possibly cauing my gauge to be reacting slow.

 

I wouldnt tap the boost gauge into the pcv. Tap it from the fpr or somewhere on the manifold. and you would get a better response posting the forced induction forum

 

NO NO NO its not tapped in there i just had a quest about the PCV system thats all


i have the gauge right in the manifold and is slow moiving but what im saying is that i might have a leak at the pcv where the hose goes on the valve could that make the vac read lower??? and make the gauge slow

 

ok well i i unplugged my mech stewart warner boost gauge on my car and ran a single rubber vacuum line from the manifold through the grommet on the firewall and hooked it up to a profession vac/psi gauge that one of my mech's at work let me borrow. and this gaguge says im reading -19 at idle and it is not slow moving at all. you smash the gas and the gauge is instantanious. what u think?? do u thing this would affect my gauge having the plastic line run into a rubber one then have the rubber one go to the manifold?? thats how my stewart warner one was. u think that was the prob? or just bad gauge

 

If you have a bad pcv line it could make your manifold have less vacuum at idle.

 

TOOK OUT PCV AND CLEANED IT AND SHOOK IT AND IT STILL RATTLES SO IS STILL WORKS

 

isnt a pcv vlave a check valve? one way? so how could it see boost and vaccum? its designed to close
