Yeah I read a bunch of threads about catch cans on these think I’ll spend money elsewhere lolI’ve ran DI gas engines for a fair bit of time. It seems that blow by oil is typically the culprit, with crud building up in the intake.. Lots of threads here about catch cans and most report zero or very little oil in the can. My advice is just drive it and enjoy it. Mine runs 87 octane just fine thank you.
