Koehler 25 hp blew oil everywhere

So you didn't do as I requested?

I requested that you remove the valve cover and start the engine, and your problem would be apparent.
And yes, it is a very common problem, buy the full kit and do both heads/gaskets......

Back in the day, when Kohler knew that they had a big head gasket problem, so they put out whole kit, but when the kohler customers brought their engines in, the "techs" just slapped in a new head gasket that they plucked out of the update kits, so many dealerships kept a whole wall of Kohler bolts/kits.... etc....

And many of them just replaced the blown side, and the customers brought back the engine the next year to replace
the other side, and sometimes both..... And many came back some more times, which knocked Kohler out of favor
totally among the mfgrs. and Kawasaki took a big foothold. Hell Generac was doing pretty good too until they hopped in bed with Dixie Chopper....

Are you sure it's motor oil that sprayed? If the mower is hydrostaticly driven, there is high pressure oil there. If the hydraulic oil got on a hot surface, it would smoke and maybe ignite. gregjo1948

Sorry, it is a BREATHER cover gasket.:wink: Not sure why the link shows valve cover. Definitely not that as you can see in the picture. Upon further research I found other discussions about this going bad on other peoples mowers with the exact same symptoms as mine.
