What type of oil are you using?
AMSOIL 20/50 racing. If I was getting blowby, then wouldn't I see some evidence of this when I removed my oil cap a bit of pressure????

Oil level is between the two marks. Always has been until just recently when I was running it towards the bottom mark.

Oil Pressure is good.
