I have a L2350 tractor that seem to be getting fuel in the oil. I was using it on a slope and oil blew out the vent pipe on top of valve cover. I checked the oil and noticed it was way over full. I have read it could be the injector pump, is this tru

If it is truly fuel in the oil it is more likely the transfer or lift pump. It could also be tractor hydraulic fluid which would most likely be the pump shaft seals.

Ruger, I am attaching 2 photos of the dip stick but the oil doesn't look like it has a foam texture. But I have not cranked the tractor in a week or so dealing with some health issues. The oil does not smell like fuel either. The oil is thin and will just run off the dip stick. Sorry for being so dumb but have not worked on any diesel before.

Unless it us using fuel like mad, it's more likely hydraulic fluid.
Check the hydraulic sump and see if it's low.

Neither diesel or hydraulic fluid will foam in the engine.
Hydraulic fluid will not hurt the engine, so drain some off, check the transmission sump, monitor both and see if you loose hydraulic oil and gain motor oil.

Did you see the pictures inside the quote section in post 4. I imagine you can move them into the reply section instead of the quote section.

They show a strange dipstick but I don’t know what that means to his problem. I know when my tractor was leaking hydraulic fluid into the engine oil it was still pretty dark oil on the dipstick but it was not pumping that much hydraulic fluid into the engine.

Yes, I forgot to do that when I replied.
