Toro pours oil out of the top shaft oil seal. Replaced the seal. Same leak.

Export threadAfter removing the blower housing, try moving the flywheel back and forth. Try different positions by rotating the flywheel a little at a time. Sounds like their could be upper bearing damage that is allowing the crankshaft to move around in the seal. Make sure the seal was also installed correctly and not too deep, allowing oil from the passage hole to come out above it.

Before I changed the upper seal I used a run-out gauge and could see no play when rotating the shaft. I was looking for a fix for my friend who was told by the dealer to junk it because after 600 hours the 17.0 Kawasaki engine warps and pours oil out the top and cannot be fixed or replaced. This does not sound real to me. I am wondering about the air filter inside the engine that shows up in the parts book. This sounds really strange and I wonder if it is cooked and needs changing? The oil is not coming from around this flat cover for the air element. I checked carefully and it just appears to be blowing by the new upper seal just like the old seal. The new seal did not seem to go into the case excessively. I did not use RTV and just lightly tapped it in with a large socket. Is there a procedure to measure the depth of the oil seal?
Warpage doesn't seem plausible to me either. It sounds like either the top bearing/crankshaft gets worn or egg shaped allowing the crank to drift enough for oil to get past the seal, and with pressure lube oil would really flow out from around the seal in that position. It is hard to describe. It wouldn't be runout like something is bent, it would be side to side movement in one direction, but may not move in another.
