PVC and catch can question

[GTOMayhem]

I understand PCV valves allow varying degrees of vacuum depending on engine application. There is even an adjustable one. Someone with more knowledge than me will need to fill in some details, though. Also, I think Billy Nees just runs a vacuum brake booster check valve as a PCV. He will need to fill in the details.

Jeff,

You have options.

You can put a Wix crankcase breather filter, P/N 46978, between the valve cover and PCV or breather.

Another option are Speedway Motors PCV Grommet Baffles.

Or, weld tubes on the valve covers and put breathers.

Thanks Joe. I ordered the grommets from Speedway
