Kohler courage vtwin 22hp, Finding oil around the base of the engine during use but not above, removed pto and drive belt seal is damp leaks from the frame a drop or two after each use. Pto engaged at next use it squeals a few seconds also (wet belt/clutch?) And resolves.
Was going to replace seal, can't find anything else. Pto was soaked with oil when I bought the mower 4 runtime hours ago.
Could be something as simple as the seal. But just as a precaution, remove the spark plugs, and while turning the engine try to move the crankshaft back and forth. I have seen causes where you would only get a leak while running and found that both the crankshaft and sump bearing were both badly damaged. There would be one spot that would when turned would allow the crank to move enough to open a gap between the crankshaft, and the seal lip.
Got it in there with pvc, seeing wet oil near mounting holes up top on the oil pan hopefully just residual and the pan isn't cracked, motor bolts were loose when I bought it.

The picture you have on here did not look like it was coming from seal but higher up. Like pan gasket.
Well it wasnt the crank seal, oil still collecting around the motor mount bolts and ends up between the motor and seat after mowing. Hills make it worse. Motor frame bolts were very loose when I bought it so cracked pan?
Also it sounds like one of the spindle pullies squeals at initial pto engagement, I already did all new deck spindle bearings and idler pullies.
WHEW! I found it. I had to bypass the blade safety so I could stand behind the machine with the blades on at high rpm to detect the leak, for some reason it didn't leak much if any without load.
Anyway, it's leaking in a pinhole sized space in the sump gasket near the starter, i'll have to remove the engine to fix.
My question is, any gotchas here? Is permatex ultra grey an acceptable sealant for longevity?
this is a Kohler SV720, it does not have a gasket just sealant and by the book loctite 5900/5910 is specified, what permatex readily available can i use?
Well boys, I removed the engine and resealed the sump with yamabond #4, let sit for 24hrs and filled it back up with oil, cut with it for just over an hour now and.... NO LEAK!
I also increased the revs to 3500 no load by moving the governor spring from #1 to #3 on the arm, no harm right? blade speed regs etc.
One last thing, when I start it choked and immediately move to high throttle it hunts 3100-3300rpm for 15-20 seconds then smooths out, that normal?
