CV-746 PCV valve replacement
« on: August 13, 2021, 02:51:40 PM »
Is there a currently available AC or aftermarket replacement for the CV-746? Looking to replace incorrect vale in my 69 Z-28.

Lots of replacements for the CV-746 (P/N 6484525) but none that I know of are "assembly line correct". If you need the "correct" one, you're going to have to pay HUGE bucks!! Do a search on ebay for 6484525.

LLoyd posted a really good thread on the "correct" valve HERE if you need more info.

Not looking to pay the huge dollars for the assembly line replacement. Just wanted to purchase current AC or aftermarket (Fram, Standard, Wix etc.) with the proper valving and flow rate, if there is one available.

Fram  FV178 is listed as the right one on their website. It's the only one I could find when I was searching and is the one I use. It's stamped 2057.
