He never tightens his carb bolts, and he has a hellacious throttle return spring, actually two of them.... |

Re: Adjustable PCV Valve
On my 301 4V I use a power brake check valve with the crankcase sealed. I like to TRY and keep some vacuum in it. I can't tell if it's worth anything but it doesn't seem to be hurting it.

Re: Adjustable PCV Valve
I don't think you can pull much vacuum in the crankcase with just a PCV ..Maybe with the check ball completely removed.. Would be hard to tune that set up ;-)
You need the header hoses for high speed suction. Of course, not legal in Stock. I just use the PCV to help keep more of that thin synthetic oil inside the motor.

So no breather on the cover? Just the brake check valve on one of the valve covers? Or being a Pontiac, the valley pan? Rick Thomason GTOMayhem |
