RE: IML: PCV systems and other California smog trivia; Was: correctcarb for '67?

["Frederick Joslin" <fljoslin@xxxxxxxx>]

My 1966 Newport 383 2bbl was set up like that. The PCV valve was on the passenger's side valve cover and there was a simple breather cap on the driver's side valve cover. BTW, Mopar started to make these PCV valves again recently. They are in chrome and sell tham as HEMI PCV valves, but they are correct for the mid 60's and can be painted to match you engine. 

My 1969 LeBaron has the breather cap connected to the air cleaner by a hose.

I just checked, and my 67 doesn't have any connection
into the air cleaner housing. Just a single snorkel.
I think it sucks in air through the oil fill cap,
which is on the opposite valve cover from the PVC
valve.

On a 350 chevy, I know there is a small, separate
filter on the PVC pipe inside of the air filter cover,
between the cover and the large round air filter.
