just for a been-there-done-something-similar data point: make sure you don't have a failing headgasket that lets oil weep out and spray yr boot. Had i not experienced this on my G/S's orig 800 motor i would'nt have believed it was possible: this motor had an upper cyl stud backing out of the case which made fully torquing the head impossible. With the head torque uneven the head gasket started weeping oil, but not enough to compromise compression, go figure. The cylinder in question (right side) weeped oil vigorously from the top edge of the cyl/head interface, such that slipstream air put an oil stain on the right leg of all my jeans and riding pants.
Again, i would have expected compression loss but it never happened-- the oil leak just got more severe until i swapped motors.

seals on the pushrods or a failed breather are statistically more likely (in that order), but check yr head gasket area while you're eyeballing. The quick clue-in is oil from the head/cylinder joint fins that is confirmed not coming from the valve cover.

The other suggestion was just replacing the seals altogether. That's probably the route I'll go. Not quite what I had in mind with my bonus this year.
Pushrod seal replacement is not the big bugaboo it's made out to be. About $50 in parts and 2-4 hours of time. JT

Laugh Oil Leak

Thanks for the comments; really appreciate it.

Well, i did take out the intake tube and saw oil coming out from the breather tube. So if a failed breather tube is the problem and oil is coming out from it; how do i deal with it? Change the tube? Or is there something else i need to manage?

The push rod tube seals is also a goner. This is obvious in my case because i can see clearly the pieces of the seals already falling off due to wear and tear. Just that in this case after i removed the intake tube and tracing the flow of the oil, it does seem that oil from the breather tube is a higher possibility.

So any suggestions as to how i can manage this? Should i remove airbox, clean it up together with my air filter (KNN) Change to new intake tube for better sealing at the edges? What else should i be doing?

Just some of thoughts here. Thanks.

Try turning the hose clamp around where the screw is on top. That should eliminate the breather oil leak (for a while).

It may not be a failed breather, but blow-by caused by worn rings/valves... do a search for breather and see a thread I started... I by-passed the stock breather system and put together a new one that aviods the carb-fouling original OEM design...

Oh, toss the K&N filter.... do a search to find out why.... especially if you ride your GS off-road.

Sounds like you have a well worn bike, you need to do some testing, leak down, like previous poster mentioned. It's got lots of blowby that's overwhelming the breather and pushing it out to the carbs. Top end rebuild time. Fix the push rod seals then, as well as anything else. Have Fun.

oil leak

im sorry...but what do u mean by 'lots of blowby'? Not sure what this means...appreciate your clarification. And yeah,...it should be a pretty worn bike by the looks of it. I am taking my time to build it up again and is looking at various options,.. Thanks anyway for your comments.

It might be a good time to do the rubber intake sleeves too.

It's not hard, you just need to be careful. If you can adjust your own valves, you can do this too.

This would be oil blowing by the worn piston rings or valve guides...

Oil Leak

Well, cleaned up the air filter and airbox and the oil stopped lieaking for over a week. But it seems to be coming back again...i have noticed a little oil at the bottom of the carb..not enough to drip on me right now..but will monitor it. Push rod seals is worn but in tis case i am convinced it is not the cause. Dunno whether if replacing the breather tube will help?
