I have a volvo ad 41,when engine gets warm oil comes out of breather filter.any suggestions.thanks.bee jones

check your oil level is it overfilled.

Is it just oil or is it smokey and are ther gases coming out?

[bee jones]

oil level is ok and it is only oil

[delmarrey]

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.
