Correct PCV Valve for 1968 Camaro 327 V8 Base Model
« on: September 17, 2023, 06:03:29 AM »
Hi First Gen Camaro Experts -

I have a 1968 Camaro base model standard V8 327/210 hp with a production date at the Norwood plant on May 14, 1968 (05B).  I need to install the correct PCV valve for judging competition at the Concourse level.  In doing some research, I understand that the correct PCV valve might be CV736C with p/n 6423695, but that there were two variations of these valves.  The late design being cast with an extra step and the early cars had a spun design with a flat top.  Is CV736C the correct PCV valve for my car and what would be the correct variation?  Many thanks.

cv736c 6423695 is the correct # for your car. There is a design change but not sure what it was. Maybe somebody else will chime in.

Hi all -

Many thanks for the information.  In the 67-68 Camaro judging manual it states that in 1968 "the PCV Valve is CV736C for all V-8 Camaros except the Z28 which received the CV746C.  Two variations of these valves exist with the late design being cast with an extra step.  The early cars had a spun design with a flat top."  My car was assembled on May 14, 1968 so would it be considered an early car and have been given a spun design with a flat top?  Or would it have received a late design?  More importantly, did the two different PCV designs only apply to the CV746C PCV valve used with the Z28?  Thanks again.  gwp4

Is there any notation in the AIM regarding the valve?
