Need mo info

It could be several things:

How many hours on the motor???

Cylinders are polished
Rings are cracked
Motor is getting too hot
Breather cap may need replacing

Just to name a few................................_/)

If the cylinders are polished or rings cracked, then you will get alot of blowby exhaust gases. Or anything else that increases exhaust blowby.

This will result in a smokey gassy discharge from the crankcase breather.

If it is a little bit of oil contiuously then probably need to replace breather, If it is more than a little bit then it could be a blocked oil return valve passage.

I have had the little plastic seal of the top of the oil bottle fall in and plug a return hole before.
