Anyone had an oil leak at case seam?

[Dawgboy]

Looks like I have a small leak at the seam of the lower engine case? Wonder if trying to work some high temp RTV silicone would seal it up?

What motor?
How much leaking?
Only real fix is to crack the cases ... Some leaking ain't gonna hurt anything

Clearly oil, not grease or tar.

There is a small spot the size of a quarter or maybe a 50 cent piece on the ground after its parked. Stock motor (117 S&S). I live with it before I pull the motor and to a tear down. Was wondering if the RTV would work. Maybe Ill give that a try.

I would thoroughly clean the entire engine with brake cleaner, then start touching with small wipes above and continue upward where you think the oil is leaking. I thought my was leaking at one time, followed the fresh oil from the seam to the oil sending unit. Very-very hard to find and trace because the oil was clean. I had to do this about 3-4 times before I found the leak. It's almost like an attic leak......the water drops in one spot but the leak is yards away from where the water drops.

Is it coming from the sump drain?

I hear that. I need ot start high and work down. I don't see anything around the case - jug union or above. Did see a little drop hanging from the leading bottom edge of the guard at the trans output. Thought that might have been blow back from a leak ahead of that.

Grant,

My drop was hanging from the center seam the same as yours...I thought the same thing, how can I seal this. Later after cleaning, touching looking for wetness over and over, I finally discovered a little run of oil from the sending unit, running along the side, down a bolt, across to the center and then just hanging.....what a relief. Tightened the sending unit, no more leak.

Thanks Rick. I'll give that area a closer inspection
