I have a Leak-Coming IO-540 and I am trying to track down the leaks...
It "appears" that oil is leaking from the S-Tec starter...now I know the starter does not have oil in it to leak so I get that...I looked in the Lycoming Engine Manual and it seems that there is no gasket between the starter and the engine block mating flange. I have not (yet) had the starter off so other than the black and white picture in the manual I do not know what is above the starter...
I assume that it is the engine crankcase seam above the starter leaking and dripping down and through the starter.
So the questions are:
Is there some way to fix the oil leak of the crankcase seam without having to take the engine apart (silicone/ epoxy seal/ JB Weld)?
How much oil leak is acceptable before I need to go through the hassle of engine R&R and Rebuild????
THANKS!!!
