1) That is the evap canister purge valve, nothing to do with crankcase ventilation. Easy to check if it is leaking vacuum, cap the line off with a rubber cap from any part store, and check the vacuum before and after.gthomp0805 said:Now I am told by the dealer there is no PCV valve just a check valve between the trottle body and the charcoal canister. They want 78.00 for the valve. Wow. What a rip. eeuroparts has it for 10.00 or 16.00.

I don't know the V6 well enough. I think Ragtop is the resident expert or close to it.gthomp0805 said:I appreciate this information. thesaabsite has it for 143 and change. Do you know why I would not get vacuum to the fuel pressure regulator? There are 2 ports coming off of the throttle body. One goes to the regulator the other is capped.
I have not worked on the 6-cyl engine. I assumed someone with the same model would pick up the thread. The diagram shows two hoses, not sure where one goes, perhaps the TB. The second hose looks like it drops right down from the bottom side of the intake manifold. Seemed straight forward to follow the hose, but perhaps it isn't, sorry.gthomp0805 said:There is no hose off the intake manifold. There are 3 off the throttle body..
