Adjustable PCV
IMO in summer, or warmer climates a pcv-unit is much less of an issue then in cold climates, where water condensation can be quite severe in the engine crankcase.
With a lot of water inside (which turns into the white sludge), you really want some more ventilation (read: leaky pcv) in the engine.
I've added a transparant vacuum canister in the line to the pcv, and the amount of sludge forming inside was worrying.
But it did allow me to tune/select the right pcv-unit to limit the sludge build-up to 'acceptable' levels.
