Crank case ventilation test

SnoEclipse · 07-07-2009

The questions that haven't been asked & answered are; what are the factory specs for crankcase pressure, piston blowby, and is it good or bad to be higher or lower than the spec.

Otherwise is just anecdotal speculation.

If an add-on catch can is the answer, the ones to get are the filter bottles for compressed air lines. Loads cheaper and more durable than the tiny things that are sold as PCV catch cans.

Except that the clear plastic they are usually made out of specifically mentions that it should be used for chemicals like motor oil, and will fail eventually.
