Ever since I rebuilt my top end on my '96 Heritage, I have been getting a lot of oil blowing by my air filter. My rebuild included S/E Heads, S/E flat top pistons(.005" over)EV-46 cam, S/E ignition module. S/E coil, S/E adj, pushrods, and new rockers. I used Harley top end gasket kit C/W umbrella valves. Any ideas what is going on here.?? Thanks for your ideas.
