Oil coming out the vent tube.

I am still new to the clones and we recently had about 2 oz of oil come out of my catch can. I use 14 oz and the motor was only ran for about 11 laps, never reaching over 6000 rpms and 300 degrees. What could be wrong?

15* mount? , I would drain the oil and measure it refill with your 14 oz that is not too much. Try again, maybe it was not fully drained.

With only 11 laps on it I’d say the rings aren’t seated yet. Those clone rings can be a bear to get sealed up. Especially if a synthetic was used from start up.

rings maybe upside down on piston,
I did that once and the engine would blow oil

Is it a new engine or one with several laps on it? Excess oil out of the breather is usually indicative of blow-by pressurizing the bottom end. Rings either not seated or worn out.
