Trying to figure out what happened. After dynoing the motor, I drove a few hundred miles and noticed a bunch of oil over the front of the motor. It goes up as high as under the coolant crossover. There really is not much that could leak. I suspect it is the seal on the crank in the front.
Do I need a special setup for crankcase ventilation on a D1? I am using the regular old P1SC stuff that came with my tuner kit. So the bypass goes into the blower plastic blower inlet along with a line from the valve cover. I wonder if when that bypass lets off the >15 psi it seemed to be making that it pressurized the crankcase and damaged that seal?
Are those front seals easy to damage?
The motor was built maybe 3000 miles ago.
