I've got a Kohler Command engine that I pulled from a Simplicity tractor. I don't find much info on servicing/trouble shooting these engines on the internet, so I thought I'd try posting here to tap into some of your experience with them. I know CCC/MTD used the Command in their 2000 and 3000 series tractors.
Here's the problem:
The engine has no power other than to move the tractor around the yard. If I engage the mower deck, it will bogg down badly.
The engine is oozing oil out of the front main seal and at the overhead valve covers - the crankcase is being pressurized. The engine doesn't smoke and otherwise starts and runs great.
I checked/serviced the crankcase breather and it is OK.
Last night I pulled the engine out of the tractor and removed the shrouds and finally the cylinder heads. There is a little carbon on the pistons, but they look good. The cylinders appear to be in great condition, no scoring and I can still see cross hatching from I guess the factory hone. The cylinder walls are very reflective - almost mirror like. The head gaskets, which I thought might be blown after I eliminated the breather, didn't appear to be breached in any way - allowing pressure back into the engine crankcase via the valves.
So what next? Do I have a bad set of rings?
What do you think is wrong with this engine?
Any help would be much appreciated.
