1967 SMALL BLOCK V-8 PCV VALVE
« on: May 30, 2010, 12:56:59 PM »
I'm trying to figure out which is the correct PCV valve is for my 67 SS 350. The AIM shows part # 6422294 as the correct PCV  valve for my application. Is this similar to either the CV-726C (6421934) or the CV-590C (6422721) PCV valves? I've seen thes listed for sale on line, and the PC-509C is advertised for a 67 Z-28, and I've seen the CV-726C advertised for a 283 Camaro. They are quite a bit different looking, so I want to make sure I get the correct looking one for my car. Are either of these an accecptable replacement for the 6422294 valve? They appear to have different size nipples on the end for the hose to connect to. Any help would be appreciated. I just want to get the right one.
Thanks,
Sean

The AC-Delco website calls out the CV679C as the correct replacement PCV valve for the '67 Camaro 350.

That's for an open system. I have a closed system. Sorry I should have started that before.

Yes it is. The one I referenced on ebay showed a PCV valve with a nipple on both ends. Can you post a picture of your valve? If not on here, can you PM me a pic? I would really appreciate it.
Thanks,
Sean

The '67 closed system is shown in the Assembly Manual in section K24, sheet A2, and calls out P/N 6422294 for the PCV valve screwed into the bung in the oil fill tube.

JohnZ,
That is correct. Does anyone have a pic of the 6422294 PCV valve? Does it look like the CV-509 valve? Or does it look like the CV-726 valve? Any help would be appreciated.

Flyingskibiker,
Thanks for the link. According to that the CV-726C (6421934) is the same as the 6422294. That's what I needed to know. Anyone need an original CV-590C still in the box cheap?
Thanks Guys for all your input,
Sean

I wouldn't know about the details...  RockAuto does say they are the same and sells them for $17.21.  I see one on ePay for $23.
