318 with chocolate milk

Ok watched the vid. I’m not convinced that the intake was the culprit. Go out and drive it, get it hot/heat soaked and have a look at the oil after. Also a pcv valve will help with the oil leaks and crankcase pressure and might be worth a few hp.
I’m taking it to/from work and around town for errands this week. Checking the oil after every trip. Maybe 50 miles so far and no signs quite yet
