[QUOTE="d_daffron, post: 733623, member: 4983"] The high RPM sealing situation is caused by lack of adequate ventillation. I dont know the exact situation but I imagine its due to using multiple feet of 1/4" or 3/8" hose and expecting it to be able to keep up with the blowby created by extended periods of WOT. Unless there is a restriction on the engine's intake, the PCV system sees zero vacuum at WOT, therefore high RPM engine sealing should be no different with PCV or without PCV. Thats also why I specified dual 3/4" vent hoses, if you increase the length of the tiny factory pcv hose without increasing the diameter you create too much restriction which builds up crankcase pressure and blows out seals and gaskets. And yes, absolutely use a catch can or at minimum a well baffled valve cover. [/QUOTE]
