At hi rpm's my car tends to leak oil from the breathers. I hooked up a PCV valve, that stopped it coming from one valve cover. Any suggestions for stopping it from the other cover?

Breather is just the el-cheapo Mr. Gasket plug in type-should I be looking for something better?

Also, valve covers are Moroso, no baffles.

At high RPMs you may not have enough vacuum through the PVC to handle the amount of blow by. I've always thought it would be really trick to run a couple of header scavengers (or whatever they are called) in the exhaust in parallel with the PCV valve. At high vacuum/low RPM operation, exhaust velocity would not be enough to make the scavengers work, but that's okay because the PCV would function. At high RPM, the scavengers would start tom take effect, and if there wasn't enough vacuum to work the PCV no big deal.

ttt-anyone else? Ideas?
