Default Which piston is gd

Hi , i believe when we high rev a ej25 engine , the engine oil will spit out from the bittle , I heard is also do with the piston we used. some piston will try to mini the spit of the engine oil and had a longer service. Wat piston is very relieable for EJ25 engine.

Sound like more than a piston problem and more like a breathing problem
