Anybody ever have an oil leak on clutch side?
Trying to figure out where its coming from, only does it under high rpm (higher pressure). I let it run at idle and see nothing! Oil all underneath motor and back. Checked oil plug and filter they are tight. I see two sensors to the left of oil filter. Could they be leaking? Or maybe stub shaft leaking?
Any input would be appreciated!

There's been a very few sleds where the oil pressure sending unit leaked. It has the harness plug on it at bottom of engine. Points towards primary clutch.
Also possible it's the seal between the balance shaft and the impeller in water pump. There are 2 seals in there. One seals coolant from water pump side and the other seals oil from engine side. Maybe that one is leaking?

Yes I was looing at that too, oil pressure sending unit. So it would be the unit itself that is faulty? Or seal behind it? Its definitely right around there that i see a lot of oil!

The seal is the unit itself. There is no separate seal behind it. If it's leaking, need new sending unit. I've replaced a few.Yes I was looing at that too, oil pressure sending unit.

The one closest to primary on outside is the oil pressure sending unit. They're spendy (over $200 USD!). The other one behind it closer to oil filter is the oil pressure switch. That one isn't as bad (about $65 USD).

Clean it off with brake clean and go run and re inspect. Bring flashlight and mirror with.
