Not sure if this is the right section but ill try anyways. Just had a new cam installed in my 92 bigtwin. ****er runs like a raped ape. Only problem is now it pumps the oil out of the crank breather. Not just some residual oil either. One trip around my city and the oil bag is nearly empty. Fill it up and do it again and the same thing happens.
Weve tried everything we can think of. Any and all suggestions would be appreciated.
I had a very reputable indy install the cam.
Reason for the new cam is one of the tappet blocks broke apart in the cam chest and took out my cam, 1 tappett, and a couple pushrods.
My indy thinks I am getting blow by on my rings and thats causing excessive pressure in the crank forcing the oil out the crank breather.
It's a 92 big twin with 93 Keith Black Heads so it has the crank breather and head breathers. I had the head breather blocked off and was only using the crank breather. Could this have something to do with it?

 

breather gear timings off,pull the cover & check it (wait,didnt read the whole post,you cant run a crankcase breather with the late nose cone,switch it back to the head breathers)
