In 2006, I purchased a new Ferris IS1500Z with the Kawasaki FH641V engine. Today I noticed a very small amount of oil dripping from the left side frame area where the skid plate mounts. I couldn't determine where it was leaking, but noticed a lot of dirty oil residue all around that area on both sides. I checked the oil and it was just a little low. After running it a few minutes while blowing all the grass and crud off, I noticed it was a bit oily around the right side head. While still running, I put my hand to the top of the case rocker (I guess that's the name for the valve cover?) and felt air blowing out, with a small build-up of oil. It didn't appear to be exhaust because it wasn't very hot. The engine has 61 hours since I had the pan gasket changed. Total hours are approximately 850. While I've replaced a wheel motor and hoses and a few other things myself, I'm not an engine guy. Could this be just a blown head gasket or maybe worse?
