PCV Valve for Poweraddres

I used to run turbocharged 2.3l Fords. We had the same problem with the VC gasket. To resolve the issue, we used a PCV/backcheck valve that was found in the vacuum system on the RX7. The NAPA part number is 29411. It is about $3.00. The valve works in conjunction with your (FORD ONLY!!! All others are CRAP!) T bird valve. (Just cause it's metal, doesn't make it the right one.) This is a link with a pic of the end of the Ford PCV box, it has the complete/correct Ford part#: EV-1217-A;E5ZZ-6A666-A http://www.merkurtech.com/merkurtech/includes/imgviewer.php?merkurtech/picturepages/images/pcv002.jpg

The RX7 valve needs to be vertical to work properly Also, it needs to be oriented so that the valve is kept closed using gravity. (I know, I didn't need to explain that. You'd be surprised how many guys didn't just "know" that on the Merkur boards.) It is easy to put it in upside-down.

We used these in excess of 25psi.
