I have a 1990 camaro 3.1L V6. I cannot find the location of the pcv valve. can someone please tell me the location? also, do our cars have a pcv filter?

thank you very much, I had a hard time finding it,
also, can you please point the location of the IAC valve?

THANK YOU FOR YOUR TIME!!

Hmm....can't say I know where that is on our cars. I could point it out to you on a 2.8 TBI though.

This one I can help.
ON MY CAR, it's the hose from the driver side valve cover to the fuel injection system.
it allows the fumes to vent thru the engine, twice.
Block it & you have extra oil leaks from internal pressure.
I know about this.
I put the wrong PCV valve on my Wife's 1968 Camaro, only a in-line 6.
Extra oil leak city. Right PCV, way less leaks. Way less.

That hooks up to the hole by the base of the distributor. It's connected by a hard plastic tube. The hose to the intake is odd size. I had to buy a 1/2 sized hose to reconnect my PCV set up, the old rubber hose was shot.
I took up extra spacing with electrical tape. Worked perfect, cured another possible vacuum leak.
Hose wore out from the oil leak at the distributor base from that joke of a rubber seal gasket on the shaft.
Use a small block chevy distributor gasket to cure that leak.

The IAC valve is located on the passenger side of the throttle body, at the top. From Overclck's pic, the IAC's butt points towards the alternator.
