[QUOTE="snakebite72, post: 12478557, member: 53293"] Your pcv system is basically useless at WOT where there is almost no vacuum in your intake (FI people pay attention) the blowby in your crankcase will look for a way out and since your engine is at high rpm your oil becomes a mist cuz of all the moving parts in your cylinder head, blowby gases start coming out thru the pcv and the fresh air inlet and guess what these gases are taking with it? yup... the mist of oil created by your eng itself and starts accumulating in your intake and some even makes it to your combustion chamber, the problem is that oil is known to lower your octane rating this is why is so critical for you forced induction guys out there. Now... with boost comes even more blowby so thats even more gases trying to come out... i have always strongly recommended a good catch can set up specially for FI engines like the ones pictured above... i have had a few customers install breathers trying to save a buck but on FI engines they come saturated with oil to the point where they start dripping creating a mess under your hood.
