[QUOTE="8WOOD, post: 1298249, member: 16395"] I don't think that much oil travels through the PVC system on startup and when not under load to have any impact. Plus the oil that goes through the PVC system is usually vaporized in the air from gases escaping the crankcase. A catch can only collects like a tablespoon of oil very 1000 miles, unless you have excessive blow by from failing piston rings, or excessive wear and tear on the piston and cylinder wall. The only reason manufacturers "reroute" the dirty air from the crankcase is to meet emissions requirements, in the old days they just just vented to air. [/QUOTE]
