Ant
We use 3 scavenge sections......2 each in the
oil pan.....and 1 in the back of the intake manifold.......with a tube mounted in the valley....
Vent with blue thunder valve covers and -12 vent hoses to a catch can......also -12 line off of dry sump tank.....to another catch can....
That was the only way we could stop
oil puking out of the motor.....BTW....we run the motor hard 2800-7000
PS....unless a engine and it seals are built to run a vacuum ....might not be a good idea....seals need to be reversed....
