I can only pull a vacuum in the crankcase by using manifold vacuum. When things are right, I can get about 6" of negative pressure. If I just use the headers, I get no movement on my vacuum gauge. I recently discovered that my oil separator breathers weren't getting all the oil out of the vacuum line to the carb. I could see some oil residue on the carb gasket under the carb (see picture 2). I'm hoping a vacuum pump style separator will cure the problem. I use the old Jenkins/Moroso pan evac system. Does anybody still use this system?
