WM Kohler engine questions

[delvis]

Is anyone using the Kohler 38 horsepower engine?  (I believe Kohler has re-labeled this engine as 36 hp).  Our engine runs great as it always has but this spring I noticed there is a slight oil leak at the front of the engine.  It looks to me like it may be leaking from the crankcase cover on the back of the motor.

Has anyone else had this issue?

How many hours can I expect to get from this engine with regular synthetic oil changes and clean air filters?

I don't have this particular engine, but have noticed many Kohler twin crank seal failures over the years...don't overlook that seal...

I have the 34 kohler on my TK and it has a leak on rear of motor (little over 1000 hours). I understand that kohler over rated this engine.

Our LT40 Super has the Kohler 38 on it, no oil leaks on ours but if you have some basic mechanical skills you should be able to change the crank seal without a whole lot of trouble...

We have 1500 hours on ours and not a lick of problems with it, we change oil/filter & fuel filter regularly, run a bigger oil filter than the stock one, keep the engine blown out clean and free of sawdust, as well as the oil cooler... We use synthetic oil as well and check the oil level very regularly...

If you service the engine regularly there is no reason it should die an early untimely death
