Oil Weeping

Had the belly pan off yesterday for an oil change (I run BMW Syn. exclusively) and noticed oil weepage (misting?) at the left forward engine case area. What's the usual culprit for any oil seepage in this specific area? I have been reading MANY posts on seals but haven't been able yet to find any info. on the appropriate seal for this particular location.

Best view of the problem area would be to lay down next to/under the machine with your head positioned towards the front tire. Looking up at the engine block from below I see the oil on the right-front of the motor's lower fins.

Cam chain cover???

Best thing you can do right now is clean the area with Simple Green or other good liquid spray cleaner and watch it VERY closely.

been there, done that

if it is a seal problem, weeping will be at the metal seams between engine/tranny/clutch junctions. your problem doesnt sound like seals. wipe all clean, ride for a while, and recheck. look close at historic probem areas, like front timing cover gasket. my '04kgt been in shop for warranty seals twice, so i speak with a bit of authority. good luck

Been there done that

I had a slight timing cover weep for over 10K miles. It helped to oil the front swingarm bearings so they came out easier! Slight weeps aren't worth getting too worked up about unless you have a warranty running out.

Perhaps you just keep an eye on it and plan the fix with other work like I did e.g valve clearance checks/chain tensioner. The only oil seal in that area is the crank seal and if that had gone (less likely) you'ld be seeing oil around the timing cover on the front right side. So it's either the rubber camshaft cover gasket, or the timing cover (most likely). You should also clean the area around the oil/water pump housing and oil cooler ports and run the bike on the stand to 'fans on' and check.

Now I can wipe my timing cover seam with a white tissue and see no oil.
