PCV System

[Kracka]

Take out the PCV valve, its not creating any crankcase vacuum with an open crankcase breather (nipple/vent on left side of the valve cover when you standing in front of the car facing the engine). If you want to create a crankcase vacuum, which is a great idea, get a product called Krank Vents. I installed them on my S2000 and oil consumption has gone down to ZERO even when I went 4500 miles on an oil change (its normal for '00-03 F20C engines to consume oil, Honda claims its due to the high performance nature of the engine and the cylinder wall lining). With the engine running, its tough to pull out the dipstick with the vacuum, but when you do you can hear the air rushing in. This will prevent the typical DSM/EVO problem of the dipstick popping out under boost. Also, the crankcase vacuum will make your engine run more efficiently and you will pick up some power (non-turbo S2000's are averaging about 3whp on back-to-back runs, the boosted ones even more).
