Hi Robert,
50 miles is hardly a break in but if you are loosing that much oil there
really seams to be something amiss besides blowby.
A question comes to mind: Did you by any chance have the main bearing
caps resized? If you answer yes, I'll fill in the details of the
question. You aren't even sure it's coming from the rear main at this
point. Could be coming from the oil pump vover not sealing well. That
too is pressurized from the cam oil lubricant and should always drain
back to inside the block. The gasket for the oil pump may be on wrong.
Now how would I know that problem? The need to pinpoint the leak is
obvious, but it could be from more than one place.
I also have a rear main seal kit that works well if the instructions are
followed closely. It isn't a positive lip seal but really gets the parts
close to the crank. Been using that on my rebuilds for over 20 years.
In the meantime, get the engine breathing opened up so there is no
buildup of crankcase pressure.
