I've a 1994 etz 251 , and have a oil leak which seems to be comming from behind the air filter housing anybody come across this problem ?

Have you recently filled the two stroke tank ?

If you have, once the tank gets warm (rising temperatures or a bit of sun shining on the tank) the oil expands and blows out of the tube at the rear of the tank, behind the air filter.

This happens more if you park on a slope facing uphill.

Bet that is not listed in the owners manual

That's one learnt through experience. I've got the stains on the drive to prove it
