check your PCV system but i dont think you have a prob there. It takes alot to blow out a rear main like that. Im thinking more along the lines of possibly a groove or something on the sealing surface of the crankshaft or possibly a rear cover problem. Rear main seals dont usually go bad that much on these engines but lots of rear cover problems. If you do it again i would replace the whole rear cover and make sure you are installing the seal properly
Thanks for the info, i put a new clutch in it about 10 thousand miles ago due to leaky rear main, replaced the rear, pilot, and put a new clutch in it. No problems until now, and only when i spray does the clutch pedal fall to the floor!
Check the pressure with a manuel gauge, seen the factory senser goes both way when it start to misread, I went from 20 psi at idle to 35 psi. I have seen them read acove 75 psi at idle and it is around 30-40 psi

I have an LPE high volume pump with high pressure spring, remote mount oil filter and 7qt moroso pan and i see 75psi warm idle, and 100psi on my autometer gauge and sender WOT. My front and rear mains dont leak. I am running a catch cat PCV setup as well.
I found out that the rubber hose that the pcv valve connects to is in pretty bad shape. It is the larger hose that has the ground strap attached to it,seems to be leaking pretty bad, could this cause high crank case pressure?
