Default how to tell if i cracked a ring land/video of the oil breather please

trying to find out if i cracked a ring land but cant see how car was very lightly run. 5psi of boost didnt go about 4500 rpms.

motor sounds good but pushed the dipstick out and oil all over.
put oil cap beather on. dipstick ok now/ no oil leaking out.

But do see and light vapor haze coming out of breather on new oil fill cap.
looking for video of a car running to see if i have a normal amount coming out.

You answered your own question. If the engine pushes the dip stick out of the tube you are building pressure in the crank case. The pvc could be bad, or you have a bad piston. Do a compression check on the engine to double check. I've been there with a old TPI car. The piston had a small crack around the top ring land, it would blow the dip stivk out under accel.

similar case.. i have an sts turbo on mine.. full throttle up in the redline and boom.. pushed the dipstick out and oil everywhere.. first to a leak down or compression test on each cylinder (start with number 7 lolll) i melted a hole in my piston and wasnt holding any presure in that cylinder : ( and if your wondering why the dipstick pops out, its cause ALL that boost gets down into your crankcase and your dipstick isnt sealed on, so it sends it flyingg.
