Where is the PVC valve? Are they cheap?

 

pcv valave is on the valve cover on left side if your looking at the front.Yes they are cheap and easy to replace.Cost about $5 give or take.

 

There should be a label on the radiator support with a diagram of the PCV and the hose in relation to the engine. BTW the PCV is another one of those items which is best if it is AC/Delco brand even though it may cost a bit more.

 

UPDATE ON WHAT THE PROBLEM WAS!!!!
Just wanted to let everyone know that this was a cracked intake manifold, with the crack being back by the distributor. Hopefully this helps anyone out there digging through these threads!

 

Well glad you got it sorted out,I take it that the black plastic piece on top of the planuem cracked?

 

I am still not clear on what you mean by 'cracked intake manifold'? Are you referring to the upper intake manifold or the intake to the Throttle body?
