Pressure Control Valve

1978 CJ7 304 V-8

I just upgraded to an Edelbrock Aluminum Intake and some new chrome valve covers. I put a grommet and PCV at the rear passenger side of the intake and ran the hose to the front of the carb. The valve covers currently have to holes or grommets. At about 1,500 rpms - there is still too much pressure and it blows the oil filler cap off.

What is the best route to take to properly have the pressure control regulated properly? Thanks.

Check to make sure the port you have the PCV hose hooked to is manifold vacuum. Not ported vacuum.

If not..Time to rebuild the motor. The only way you will have that much crank case pressure is with ring blow by. My V8 has solid valve covers, and the crank case pressure is easily managed with the PCV valve.
