B18c crankcase pressure leakage ?
Hello,
my eg set up: B18c with 82mm ycp p73 piston. p2w clearance is 0.03mm. ring gap 0.017-.0.020 open vent oil catch can connected the hole that located at block behind with an10 adapter ( delete black box)
In recently, sometime when I pull to 6000-8000 rpm , it occur throttle no response and i can listen a lot of crankcase strong pressure leakage sound from catch can open port, i see some smoke leak out from catch can.it can drive after the leakage finish. do I get the bad ring problem? but it can run normally in daily driving, no exhaust smoke , totally normal if i do not pull it hard.
anybody happen this case ?

You need diagram your catch can layout and ensure that it is proper. Very difficult to understand where this issue is originating.
