This is what I said earlier in this thread... that there must be something else going on here... to have that much 'blow by' to lift the dipstick!
I'd be doing a leak down test on that motor before I did another thing to it...
I've run some pretty potent motors in my day - big and small blocks - and NEVER had that kind of crankcase pressure...
My 427 cubic inch small block will load up the filling in the breather and eventually drip a drop or two of oil on the valve cover... but we're talking about a motor with NO vacuum (8 stack EFI) and NO PCV. I have now (just yesterday as a matter of fact) run a catch can plumbed to a fitting in the fuel pump block off plate... so hopefully that will take the bottom end pulses and keep the breather from loading up with oil fumes. The problem with having no piston / skirt - and a real tight ring pack... I think the compression height of the pistons are 1.100 so there's just not much there to control 'oil'. BUT even at 7000 rpm's -- I've never blown oil out a gasket or lifted the dipstick!!
