Doing 2nd 3 year service and pulled engine cowl and see oil what looks to be coming from under flywheel. Motor has 225hrs. It's like a black sticky black oil20240228_183349.jpg20240228_181939.jpg20240228_182452.jpg20240228_182452.jpg I'll try and post pics.

From the pictures I'd guess the upper main bearing seal needs to be replaced. Pull the flywheel and have a look.

Thanks ChampioNman I will do that.. I was doing some more checking and the one side of the T oil lines the wire tie is loose. The T is dead center behind the air box under the flywheel. Could this cause this amount of oil mess. Also found one on the port side bottom of engine that the wire tie was so loose it wasn't even over he barbed area of the hose and had oil in this area as well. Seems all the oil is on the starboard side just behind the airbox running down the side of the engine.20240228_203425.jpg20240228_203452.jpg

This looks more like the water pressure hose fitting.

Found the top crank bearing assy bolts are loose. What would cause these to become loose and would this mess bearing up? What are my options now new bearing seal assembly? Can you remove this or does case need split? Thanks for any advice. BTW can't get flywheel off to look at seal. Guessing loaned out my flywheel holder tool to somebody.

Anyone know if you can pull the upper crankshaft bearing assy without splitting the case?

You can replace the seal without splitting the crankcase.
