Filtration on the oil pan scavange lines
My question is simply this, how fine / restrictive is the norm for filtration in the Scavange lines from the pan to the Dry-Sump pump ? Thanks Mark H.

Re: NASCAR Truck engies on a road course

Re: Total Seal zero-gaps
Gapless piston rings have accomplished two things that can not be denied. 1. The claims behind the gapless ring is a story that is " Easy " to latch onto ( believe in ) . 2. It has made more than one Ring producer a whole lotta $$ . Mark H.

If I over rev and bounce it over the nose and it's hydraulic it pumps up but at least it can help bleed it back down...
