Re: Pcv
Lets also remember to keep the vented cap clean. with a PCV in use it's getting it's intake of atmosphere through the vented oil caps in these cars so road debris will be collected there over time.
Benefits of a PCV system include, but not limited to:
reduction of spent gasses collecting in the crankcase and promoting sludge build up
greating an atmosphere negative, or "depression" in the crankcase to aid in ring seal
reduction in road draft debis in underside areas of the car
aids in front and rear crankshaft seal (reduced oil leaks)
extending oil change intervals by keeping the case environment cleaner
A depression in the crankcase is always a welcome force in HP engines for all of the above reasons and more. Race fans may have noted one way valves in the header collectors of drag race cars. They are used for these reasons, especially ring seal at high operating speeds. More extreme applications actually use a vacuum pump to create case depression. PCV valves have different specs, and as I recall our sister publication (theHAMB) had quite a topic on that. Good stuff 'barners...
