Crank Case Venting

It sounds to me like someone F'd your seal when they put the balancer on or during a cam swap. How would a leaking front seal down by the crank get oil all the way up there?

Since you already have the MM wild setup, I would stick with it, and set it up how they suggest. Guys running a shit ton more boost use that without a problem. My guess is boost didnt cause your seal to pop out.

I’ve had the cam for 4 years. No issues. Even after the FI build it was fine. Did 2 super hard pulls after the retune, and that’s when it started leaking. Drove 1.5 hours home with the oil no leaking.

At what hp level do you need to start thinking about crank case venting in s/c cars?

as soon as you add any pressure, you need to know how it builds up and where it goes. So to answer your question, right away right from the start. Even at the lowest setting you need a variation of a crank pressure ventilation system and you usually need to improve on it or use larger capacity system the crazier your build gets.
