when an engine is running,by-products of combustion get past the piston rings and end up in the cankcase.
these by-products(moisture,dirt,unburnt fuel,carbon,etc)are the main contaminents that get into the oil.
the PCV(positive crankcase ventilation)removes these by-products before they contaminate the oil.
this greatly increases the oil change intervals and reduces wear in the engine by keeping the oil cleaner longer.
removing the pcv is detrimental to your engine and has absolutely NO benefits.
Alright, that's exactly what I wanted to know... just have to find a new plug.
