Kohler oil leak:
I'm trying to pinpoint an oil leak on a Kohler CV-740, 27HP twin on a Gravely ZTR. The leak is confined to the oil cooler and filter area. I replaced the oil cooler lines and clamps, oil filter, and 'O' ring on the cooler to sump. I cleaned everything up with Super Clean and ran it up however it looks as if the cooler to sump is still leaking at high rpm, drip drip sort of leak on to the engine mounting plate.
The sump to block looks dry except in this region but it has been soaked with oil from all of the leaks. Tomorrow I'm going to eliminate the cooler and mount an oil filter directly to the sump and see if the leak persists. Any other thoughts?
