Hello all.
So, I am in the process of doing some fixing up on my new (to me) John Deere LT155 and I am trying to solve an oil leak that the engine is experiencing. When I pulled the engine out of the mower, I went ahead and replaced the oil drain valve and dipstick seal, and then checked and torqued down all of the oil pump and oil pan bolts. I did find an oil pan bolt that was just finger tight so I figured that to be my issue with having oil sitting on the frame around the base of the engine. From what I can tell, this mower has probably been leaking oil for quite a while as I spent a TON of time cleaning up the area around the engine and on the bottom side of the frame where oil, dirt and grass clippings had been stuck to the metal. In doing this cleaning I figured that once I got it back together I would see if there was still a leak.
Well, after about an hour of mowing, I opened the hood to find some oil on the frame near the back side of the engine. I cannot tell where the oil is coming from since the engine is quite clean and the oil is new. From what I can tell, oil is not coming from the crank seal or the valve cover.
I have ordered a tube of Loctite SI 5900 instant gasket which Kohler calls for when re-sealing the oil pan, as well as a new crank seal and oil pump cover o-ring since I will already have the bottom end off. Is there anything else that would or could cause this problem?
Thanks in advance.
Mike
