So yesterday I was forced to redo my rear valve cover (car smoked like a freight train) haha. Got everything off and fixed the rear and the front valve cover's, plus a new plenum gasket. I got everything put back together and tried to start the car, It won't run it turns and tries to start put is does nothing. Also I found that I had a little rubber piece left over. It looks like a hose attaches to the top, but for the god of me I cant find where it goes... lol

 

That's the PCV valve. It goes in the rear valve cover and is located between the UIM and TB.

 

edit: ^^ beat me by a few secs lol

That's your PCV valve, might wanna hook it back up

 

Got it lol, but what would cause the car not to start

 

Air is escaping without that PCV valve

 

Without that valve in place, you have a huge vacuum leak!

 

Pcv is what causing the car not to start no pressure to being built for a combustion. In another words you have big leak or opening in the crankcase not letting the car start.

 

Fianlly got the car to run (had to work) now the car starts fine but as soon as it idles down it starts running like crap :/ I've rechecked everything but I still hear a vacuum leak from somewhere.....
