To PCV or Not to PCV...That is the question.

The combustion gases that leak past the rings, and it does leak some,, is full of water vapor,, unless you suck that moisture outta the crankcase,, you'll start finding condensation inside your engine,..

Member Cannucky wasn't running PCV,, and wondered every time he pulled the Valvecovers to adjust rockers,, why there was grey sludge, and condensation on the inside of his valvecovers, and grey sludge accumulating the the valley depressions,, no pcv to suck the vapors,,

His carb (DEMON 950(?) didn't have a vac fitting, so he installed spacer plate with vac fitting under the carb,, no more sludge/condensation..

First hand.. we both saw it..

AND it's well documented,, do a search..
