Kohler CV940 Oil Leak

I have an Exmark with a Kohler 34 hp CV940 engine purchased in June 2011. It has 328 hours on it. It leaks around the rear-most rocker cover. I replaced the gasket friday, came in today and there is oil all around the bottom of the cover again. There is no sign of oil coming from anywhere else. I removed the cover again, checked the gasket, checked the cover for damage/defects, nothing. My next move is to buy a rocker cover kit, and replace the gasket and cover and see what happens.

Any ideas on why it is leaking? It is properly torqued using a torque wrench.

We have 3 Exmarks with the same engine purchased at the same time. This winter I had to replace the rocker cover gaskets on the other two units. They are still good but I had to have the sump gasket replaced on one of them. Never had a problem with Exmark with the 34hp Kawasaki.

Hey groundsmechanic,

We're sorry to hear that you're experiencing some difficulties. We have an idea of what may have happened.

Please send your engine's spec and serial numbers to us at enginefieldservice@kohler.com so we can look into this for you. Thanks.

-Cindy

I don't think Kawasaki would be much help. I don't think they have the parts diagram for the Kohler engine. Lol
