Oil leaking into flywheel case.

[rickc360]

What would cause a L4350 to suddenly start leaking oil into the flywheel case. The clutch assembly is flinging the oil out of the vent area behind the cover where the main frame for the front loader is bolted to the flywheel case. I had been working on a steep downward angle. Rick

Sounds like you have a transmission shaft seal issue.
It's probably been like that for awhile it's just the steep angle is now forcing fluid out the bad seal.
