Sorry and other things to check for would be;
Dipstick calibration - fill the engine with the recommended oil volume, run it to prime the system, then let it sit for 10 minutes and see where it registers on the dipstick (level ground please obviously!). If dipsticks have been switched up, you maybe overfilling it.
The other things of course is make sure that your crank case has a breather set up, and when you rev the engine look for excessive exhaust blow-by (from rings or valve stems), as even with the correct breather, high blow-by will increase crank case pressure to the point where scroll type crank seals can be over come and leak.
