The engine has to have a way to breathe and I've seen those who will delete the road draft tube and put a closed breather on the oil filler tube. They won't run a pcv system because they don't want to hack up the finned Corvette valve covers. That will cause a massive pressure in the crankcase pushing oil out wherever a place can be found.
I experienced that on a cherry 57 Ford in 1964 in California. After a 1000 miles or so the dipstick blew out, dented the hood, covered the right side of the windshield in oil and wiped out the bearings.
