nobody knows i've stumped you all or are you just above my lame thread

Yes, but I will answer anyway. It is in the oil fill housing. If it is on the 75 at all. There should be a port out of the side of the housing next to where the oil filler stalk sticks out. $10 for a new one from Porsche I hear (just the valve, not the whole housing).

i do have a "port" next to the oel filler neck, but it don't look like a pcv valve. it looks like a permanent part of the oel filler box assembly thingy(technical term).

Infadel! You dare argue with me! Sorry, got ahead of myself. Is there a kneraled (lotta grooves going vertically, like a tooth paste cap) nut on it? If so that would indicate that you can remove it. But, if it aint broke dont breakit. I am not sure of the test for it, but I am pretty sure it includes blowing on it to see if too much air passes one way or another. It is your crank carse breather.

no nut or anything on it. just a plain old tube. po had a FLAPS rubber heater hose going from it to the air box in what seemed to be the correct place.

no sir. it goes vertically on the opposite side of the filler neck.

Why do you want to find and change it? Your year may not have one It would have been that thing with the intimate parts on the inside. I am not sure where the hose to it is supposed to go. I am sure there is a picture some where.

i was just curious. never saw it for all the times i've had my head burried in the hell hole. just wondering where i could find it. i didn't consider the fact that my car may not even have one.

not all oil-fillers are created equal!

the ones where the port goes directly into the filler-neck don't have a PCV.
the ones where the port goes into the bottom square part of the filler either have a PCV inside the square part or (on early cars) just have a hollow space with some baffles inside to trap the oil ...

so is the filler neck the only place where the pcv valve would be located on a 914?

Ya know I'm only messin with ya.

i give up. my pcv valve can go 2 hell :finger2: hahahahahaha!

75 & 76 smog motors don't have a PCV valve. The oil filler is different, there is a baffle instead of a hole for a PCV valve.
