did you have to drill holes all the way through the valve covers for the baffles?
I've drilled and tap the bosses for #6x32 screws (CRS the length, 1/4 to 1/2 inch
) and used small flat washers under a piece of flat thin aluminum sheet with red Locktite without going through to the top
I'm going to have a weld in baffle to stop my vacuum pump from sucking so much oil into the surge tank today on a set of cast aluminum valve covers that may be a set of no name Indy covers,I'm not sure where they came from though
I used a Moroso vacuum pump fitting that has 3 sets of three 1/8 holes on the flats of the fitting facing the outside edge of the valve cover for the suction side, I'm really surprised on how much oil it being suck into the fitting into the GZ vacuum pump, probably around two to four ounces a 1/4 mile run
Hopefully the baffle will stop that oil from being sucked out of the motor
