PCV delete ideas/vent with catch can
.
I have had some headaches with my old six along these same lines.
There was actually a kit, (an old one), to change over from the open crankcase vent to a closed system.
Several of the street racers around here set up a vacuum system so as to always have a negative pressure in the crankcase.
I had an idea that I have not followed up on yet.................
There are old school / old type fuel pumps that have a vacuum pump stacked on them as an assembly.
They were for suppling the vacuum for the early windshield wiper systems.
With some work I may be able to use one of those to help with my problems.
More modern engines like you guys use, may see a benefit from drawing vacuum on the crankcase in order to improve things.
Worth looking into.
