For those gurus who have done this before, how common is to see some oil leak at the base of the cylinder after reinstalling it.
I had to pull a cylinder for some work and installed it back with all new o-ring and other gaskets. Torqued the cylinder based on SI 1029D and did a two hour flight to break/set the rings. After the two hour flight, I see a bit of oil (maybe three drops worth) at the based on the cylinder.
I couldn't determine if the oil is coming from the cylinder, oil return lines or oil tube (this was #3 cylinder) and it is all possible that is some leftover for lubricating the bolts, etc.
