440 w/TorqStorm SC - Boost Getting Into Crankcase?? Valley Pan BULGE

I guess I'm just confused as to why it had enough pressure to bulge a valley pan but not blow the dip stick out.

I'm with RRR, just because an engine can break in asap doesn't mean this one did. Plenty of machinists out there just run a dingo ball hone through the bore after they cut some metal out and call it good. Plenty of engines out there don't get broke in. You breaking in on really good synthetic oil?

If boost is a factor, I'd run the overlapping rings (can't remember the name), or the ones with the little holes in the pistons or whatever the hell else it is that blower people use. If you got that much pressure getting past rings, something is up.

You sure you ain't got a hose plumbed wrong, like from the vacuum port on the carb to a breather, or something like that?
