B6200 Kubota oil leak

Mtractor · Sep 18, 2013

My Kubota B6200 has oil coming out of blow by tube. It has no
blowby at all. It does this after running it for about one hour.
Tractor has strong compression. I also noticed the hydraulic oil
dipstick level goes down. Kubota dealer said an o ring from
around hydraulic pump could be worn and allowing hydraulic
fluid to run into oil crankcase. Could anybody help confirm
this?

Well first of all when you shut the tractor off and let it sit for couple hours is the oil level over full. Will not as simple as an o ring what you will find is worn hydraulic pump. Replacing the front shaft seal will NOT fix the problem. will require replacement of the pump or rebuilding the end plates. Pressure from worn pump is forcing the oil by the seal and into your engine.

If the tube you are talking about is on the valve cover you might have a worn rocker arm bushing. Oil pressure squirts more oil out and can get up this tube. Rare but can happen.
