Hi, I recently got a hand made car that has a Buick 215 engine in it. There is no PCV valve, just a breather cap on the driver side, and a hose going to an aftermarket chrome air cleaner on the pass side. I guess the PCV valve is supposed to go in the hole in the pass side valve cover? And connect with a hose to...a T fitting at the back of the carb? or where? Right now, the transmission vacuum modulator (for a different transmission) is connected at the back of the carb. It has a 4GC Rochester carb.

Any info...pictures or description...of the stock setup would be a help. engine1.jpg

Chances are good that it didn't have one new, unless it was a Cali vehicle. Does it still have the road draft tube sticking out from the bottom of the engine?

CorvairGeek's right. Unless it's a California engine, which started requiring PCVs in 1961, most car companies didn't include factory PCVs until 1964. The 215 V-8's final production year was 1963 and British Rover bought the rights to the engine after that.

I think you'll find that they had PCV by 63 everywhere....at least, that's been my experience. 1962 non-california cars had draft tubes.

Thanks for the pictures...looks like they added a 1970s Ford cap with the PCV valve in it to that one! I won't do that.
