For those of you new to this problem it has been discussed many times over many years and this is the best way of fixing the issue for good if you want to give it a go. Follow the link found below and read the thread, it gives a pretty good explanation of the problem as well as a permanent fix for this pesky nuisance. As always, take care mates!

That's not the same weep hole, Keith. There are two weep holes: one for the coolant, when the impeller shaft seal is bad, one for the oil, when there is excess oil in the bike (my case).

Better check again Froggy. There is only one weep hole! Unless of course you are refering to the breather in the backbone of the frame a weep hole. :twisted: (or the two weep holes on either side of your nose)

On the 01-03, there are two weep holes.
One at 9 o'clock next to the waterpump, for the water, one at 11 o'clock, for the oil.
You can check the parts manuals. The oil circuit in the cover is a bit complex. What I think it does is go up from the crankshaft into the top end, through the cover. If the passage is blocked or if there is too much oil, then it goes up into the oil weep hole (I was thinking it was doing the opposite until now).
Now I think I know what I did wrong and I will open the rocker cover. Obviously I put too much sealant in there in January and that's why the oil is weeping. Which is not a good thing, because it means that the rockers are not lubed properly.

I had an 02 so I do know what I'm talking about. There is only one weep hole unless your bike has been customized. No one has ever mentioned two weep holes in all the years of weep hole discussion. (it's at the 9 o'clock position) On the outboard side of the weep hole is seal to prevent coolant from leaking. On the inboard side is a proprietary bearing with a seal that goes up against an o-ring to prevent oil from leaking. If one or both seals has gone bad, it is possible for coolant to leak, oil to leak, or both out of the same hole. I would have to disagree that overfilling the motor with oil would lead to weep hole leakage. Overfilling would far more likely lead to blow-by escaping through the breather assembly.

Oil circuit in the cover? I don't think so. Your talking side/clutch cover right? There is no oil circuit in the side/clutch cover. Rocker cover, yes.
If sealant covers the oil circuit in the rocker cover, your rocker assembly won't get lubricated. This won't lead to oil coming out of the weep hole by the water pump. A marred wp impeller shaft, bad o-ring or waterpump bearing seal will cause oil leakage from the weep hole.
Here's a great weep hole thread by Eric "husabutt" and it applies to 2001 and later models.

Yes, Eric, there is an oil weep hole on the left cover on my 2001, and now I think I know what the deal is.
Bobzilla included all the broken parts and replaced parts from this bike and the old left cover was replaced, I guess with a 2003 version
Here is the snapshot from the 2003 manual. The 2001 manual differs.
Bob, can you confirm?

YA know, I had an 02 as well, and replaced the seals to prevent that weep, and i only remember their being one weep hole
My bad.
Apparently there is an oil passage in the cover.
The illustration you supplied can be confusing as makes it seem as if there are two weep holes when actually I think they are refering to the same hole. When oil comes out, it's an oil weep hole. When coolant leaks out, it's a coolant weep hole.:lol:
As far as your bike having two weep holes, scroll down this thread to the post from AlanNMS.
weep hole
He explains that the Nevada shop, NMS, modified quite a few covers by re-drilling the weep hole to a new location, then epoxying the original hole shut. Where is your bike originally from? Nevada, right? NMS right? Your cover has been modified. Your weep hole at 9 o'clock is most likely sealed with epoxy.

Hmm you may be onto something, but I would have to ask Bobzilla about it. He had the bike worked at by NMS. I guess I could just call them and ask them "so what did you all do to Bob's old bike that he did not do?"
BUT, on my bike, the 9 o'clock hole does drip coolant when the seal is not pushed all the way. That issue is fixed.
The other issue is with oil coming up the 11 o'clock weep hole, and I have too ideas on why:
1-too much oil (I will drop 200cc)
2-clog circuit in the top end (I will open and inspec)

Okay,
lets assume that the whole caboose is new, 1200kms old, no modification, never dissasembled or anything that may lead to damading seals or anything.
the impeller shaft rotates at a higher RMP than the Crank as it is driven by the timing drive, yes.
The bearing has some (only minute) working clearance or 'slop' where the inner sleve of the ballrace moves out of perfect centre with the outer sleve of the ballrace(this is why ballraces with more ballbearings are better for high speed applications).
the seal is pressed into the engine case so retains its relationship with the outer sleve of the ballrace, however there could be some concentric difference (the inner sleve of the ballrace is slightly out of line with the lip of the seal) when under load due to the rotation of the shaft (gyroscopic force) wanting to pull it in a given direction (not including any imbalance in the shaft or its drive train).
it is possible then that under constant and prolonged load (with a higher oil level - more of it splashing around in the crank case and onto other surfaces where it typically would not end up) that the weep occurrs?
The shaft would recieve lubrication normally, but say there is now significantly more of it moving around in the crankcase, the likelihood is that some of it will find new passages to escape or be drawn into (lets not forget that the hot oil may be drawn through by capilliary action) and becomes apparent when it appears at the weep hole.
I would dis-quallify this by saying that I havent pulled the pump and housing apart yet.
of coures damages seals, pitted impeller shafts, etc will also cause this, so the more an engine is pulled down and re-assembled, the more likely that a component has been flawed in the process.

No. The crank gear drives the clutch gear which drives the impeller gear. Both the crank and impeller gears have 29 teeth so they both turn the same speed.awilksch said:
found my oil leak. Bloody rocker cover had a loose bolt, to the point where there was only 1 turn of thread stopping it from dissapearing on a ride.
For the heck of It I plugged the weeping hole just to see what would happen?
Of course I new the worst would be oil in the water or water in the oil!
Befor either fail bad enough you should already be aware! A :roll:

Hi all,
notwithstanding all the advice that has come before, I have found that a little less oil in the cases seems to alleviate the weep, this may also be in conjunction with the heavier oil i am currently using (Bel Ray Thumper 20 - 50W)
just thought i'd throw in my two bobs worth again, could always be proven wrong on my next ride though.
