engine case bolt oil leak

[r1150rt-pinto]

2002 r1150rt; i am observing engine oil leaking out from the the bolt recess/bolt on the right side of the engine, i believe these bolts are the case half fasteners. the oil leaks are coming from there. could the bolts suddenly be loose? i switched to full synthetic oil...but i do not subscribe to the anti-synthetic bandwagon. is my engine producing excess blowby and thus crankcase pressure? or are the case bolts suddenly loose? or both?! And of course the bolts (two or three of them) are not accessible without fairing and crashbar removal...either that or an elaborate extension and u-joint combo.

Any one seen this before, specific to this application? I figure solutions are: re-torque fastener(s), remove fastener(s) and clean mating surfaces and apply sealant and reinstall, or simply degrease area and apply appropriate RTV silicone. WHAT DO YOU GUYS THINK?

Interesting. I'm not at all familiar with the BMW stuff. Go online and bring up a schematic of the engine and find where your leak is coming from. Check out where the bolt goes.

I hope you don't have a crack that has somehow developed in the case.

Take my advice with a grain of salt 'cause I know NOTHING about BMW's.  but changing oil can cause seals to swell or shrink slightly due to the oil's composition and the additives.  I'd degrease the area, check again 2 weeks later.  If it continues to leak, then I'd degrease again and silicone and wait until i had a to take the crash bars off...     I'm assuming this is a seal failure and not a warped or cracked cover or loosened bolt --  which I wouldn't worry about unless you dropped the bike, or it got really hot.

I'd sure make sure the bolt isn't loose.
IF it is, find out the correct torque value and correctly torque it.
And check the adjacent bolts.
