I would like some opinions on engine breathers systems. Is setting a PCV system worth it? Should I go with the standard breathers or set up a PCV system? My concerns are about engine life and cleanliness, in the bottom end and the intake.
It's really an early pollution control. I switched to a PCV to prevent oil film on the LH valve cover. The 'closed system', with a closed cap and hose to the air cleaner works best.
Hi,
I'll add, another benefit of a closed PCV system, is a reduction in crankcase pressures. This reduces any tendencies for oil seepage through, otherwise, weak oil pan and valve cover gaskets.
Just another thought.
