I found I have some oil leakage, not severe quantities, (I dont think) but an oil leak just the same.
It is on the left side, and seems to go from front to back. Im assumimg the spread is oil being pushed back while driving. It seems to actually start around the water pump, based on where the oil is at.
Has anyone seen leakage starting around there? Is it a common issue? I wouldnt expect it to be leaking from the water pump, but its hard to imagine oil pushing forwards as the bike is driven down the freeway.
I'll try inserting a pic to show you what Im talking about.
Thanks for the input.

if a seal is going bad, yes a water pump can leak oil. time for a new pump?

Can you help me understand that? Not trying to argue at all, Im just ignorant about it. Theres the seal at the top/front of the pump where the "lid" bolts on but isnt that just for water? Im looking at a blow up on line, Theres a O ring that sits towards tha back, would that do it? I dont think Ive ever actually had a water pump ever go bad, on anything, so it kind of catches me of guard.
Thanks again

The water pump is driven off the oil pump, there's a seal between the two and when that fails oil is pushed through the water pump bearings and out the weep hole.

Would I need to replace the entire pump? Or can I just pull it and replace the seals? From what I read the pump should otherwise last quite a bit longer, I have 62,000 on it now.
Thanks

The grease in the bearings has been washed out by the oil going through them. I doubt it will last long without the proper grease in the bearings.

Thanks for the info, I appreciate it. Looks like a simple enough job in the book, I just hope the leak is where it looks like it is. I'd hate to spend the time and money replacing a working pump and not fix the problem.

My experience is that is any coolant/oil is coming out the weep hole then the bearings in the pump are gone and this causes the seals to fail due tot he wobble on the pumps shaft. When you get in there and see how much lateral movement your pump actually has you will wonder how it is still functioning at all.

while you're at it, get a couple of timing belts and swap those out, too. Only an extra $30 or so and the job is complete, you won't need to go back in there for quite a while, if ever. I would suggest to do those first so your neutral switch will still be in the same position when reassembling.
