I finally was able to direct my attention to my oil leak problem. We had our daughter's big wedding day, and the "getting over it" to deal with!
Yes, the air coming through near the upper rocker covers was from the fan at the flywheel (I said earlier I wasn't an engine guy). I took the entire top off down to the cylinders and found a giant dirty oily mess! The breather cover looked like it was a little sunk-in, and upon removal I found a portion of the gasket looked bad. I went ahead and replaced both rocker gaskets and found the inside extremely clean on both, as if the engine was brand new. I've ordered both styles of breather gaskets and covers, upper crank seal and governor shaft seal hoping to solve the issue. In my first post I mistakenly said I had my pan gasket replaced recently, but meant the lower crank seal. That area is not leaking.
Now, I guess my question is regarding the breather gasket and cover - I understand that Kawasaki had made an improved replacement kit that include both the gasket, cover and new bolts. Not totally sure about it working on my engine, I ordered the old style pieces also. I was unable to locate a replacement foam element that goes with the original style parts. However if you click on the #49109 number for the foam element on the order site, it takes you to #49109-7003 which is the new combo kit. I have had no static leaks since I have cleaned it.
My engine info on the block is FH641V49667, DS25. Anyone know if the upgraded breather gasket and cover will fit?
Thanks
