need help
i have an st220 that is loosing oil and smoking through the exhaust under load, ie foot down.
no problems starting or power loss on acceleration, oil loss also slow.
no oil in the water.
any ideas where the oil leak is coming from anyone.??

don`t want to put it into a garage for exploritary work as it`ll cost a fortune.

seems weird as it`s all coming through the exhaust so assuming it isn`t the head gasket.

and no loss in power or weird noises.

been doing it for the last 10,000 miles and got no worse.

uses about a litre every 1,000 miles although been driving at low revs since it started.

help....
