1986 GS550ES AKA 'Leaky Lena'

[Skiprrrdog]

I have a 1986 GS550ES that I got a couple of months ago. It was running (kind of) when I got it, and I have it to where it is running pretty good now. I have an oil leak, from the back side of the engine I cannot pinpoint. It was worse, so I changed the valve cover gasket and while I was in there, I torqued down the head bolts, and it got a little better, but after only a spirited 10 mile ride, there will be a tiny amount of oil on top of the crankcase, left side, right by the starter cover. Are there any known 'trouble spots' in that area I should focus on?
Thanks in advance!

Plenty of places to look, the cam chain tensioner seems to be a frequent problem spot.

I recall having some oil leakage around the valve cover gasket when I picked mine up, and it took some time for the oil that had pooled in various spots to burn off.

Although not the first thing I would investigate, the oil cooling lines were definitely suspect.

Time for a wash and baby powder investigation.
