[QUOTE="SlowSVT, post: 14084562, member: 20202"] Removing the PVC system eliminates the engines ability to purge the oil gas and water vapors that accumulate inside the crankcase contaminating the oil and forming varnish inside the engine. Just putting breathers on the valve covers will make the air inside the engine more or less "static" with nothing to draw the blow-by out of the engine where it will fester. Unless you have a vacuum pump to do this drawing thru the engine is the price to be paid to scavenge the crankcase. I would leave the PCV system in place. [/QUOTE]
