Two PVC?
I have an open element air filter. one valve cover has a PVC valve the other a push in breather.
What if I had a PVC valve in each valve cover? then run 3/8 vacuum hose to a T, then to the carb? Would that be good/bad/wouldn't hurt? Thank you

Re: Two PVC?
That makes sense. I would think the seal would be tough, but the idea is to keep the engine as durable as possible.

Re: Two PVC?
Also, a PCV is a metered air leak, installing two of them may create high idle problems. I would recommend leaving it alone. Just my opinion.

Here's an article that explains fully the actual designed purpose and function of the system.
