Weep hole oil leak

I had an oil mess after each ride on the left side and looked everywhere except the weep hole (due to my lack of Husaberg knowledge, I have to confess).

I cleaned everything up good, put everything back, bike started fine, easier than before thanks to valve adjustment, but now I realize the leak comes from the weep hole. Not a lot but I am confident this is the culprit.

I also remember that the oily mess started after I worked on the top cover, trying to fix the oil leak issue from there by applying a lot of Threebond 1211 and I wonder now if too much sealant at the top did not block the oil circuit (through that little o-ring).

Otherwise what could cause the problem?
 
Hi Frog,
I took a ride for 150kms or so yesterday, when I got home, I found a (very slight) oil weep from the weep hole Left side front of the water pump housing / cover.

My engine is stock standard, 1200 kms old, I cant explain what causes the weep, but if theres a weep hole, it must be a reason??

I reckon Faktor had a photo in his gallery showing the left side with an oil splat around the sight glass, maybe he has the answer??

I's be keen to find out too.

Cheers!

OKAY, I re-opened the clutch cover to realize that I had put too much sealant (that's one of these things I have to stop doing) and it blocked the oil from dripping back into the crankshaft (or so that's what I think it does), and instead found its way through the weep hole.

It's a learning curve, I'm telling you.
 
Yeah, but you have an 04? Things changed then.

In the 01-03 the oil recovery circuit goes through the left side cover down into the crankshaft. There is a wee hole in the middle of the crankshaft.

Too much sealant (yes, I put sealant all around, not just where advised in the user manual) will clog the passage and the oil will exit the bike through the weep hole.

One of those "only one way to learn that fire burns..." things.
 
i trid three-bond around that top cover froggy, what a load of shyyytee!. good old fashioned thick gasket muck and no problems since.

however i have now used the glass and wet 'n dry trick three times. each time that front left corner is always the last area to clean up nicely. next time i'll have to machine out the bearing and end cap housing.

because you're getting the hang of mechanical things froggy you should buy the special condom for slipping on the end of the waterpump shaft. this will protect your seal every time. i would think it's in 'special tools' and will pay for itself first time.

fryguy gave us that info....

cleqan oput the weep hole. don't overfill with oil.

hey guys, I'm having trouble with an oil leak every time I ride my bike hard. The oil is collecting around the front of the engine near the exhaust headers. I have replaced the barrel gasket, goo'ed up the rocker cover, re torqued the head and checked the valve adjustment covers. any ideas where the oil is coming from. It doesn't leak much but a leak is a leak and I wanna fix it.
 
it's in the doc ferret but there are two well known places. the first is the breather tube. it's a screw in effort and comes undone. try and get this loctited in good and tight. the second one we have been on about only today. that's the front left corner of the rocker cover. it distorts ad lets oil out.

i used a sheet of P800 on a glass pane held by clotyhes pegs.

pour water on it and then rub some soap back and forth until the surface is creamy. then rub the cover 7 or so strokes in each direction of four.

you can even spray the edge with black aerosol and rub till it comes off. then you're flat.

good luck.

There is also the option of using Wurth sealant, and BOSS sold me a can.

I will let you know when I work on that issue, which I have as well. Front left corner of the rocker cover. Leaks oil real bad.

If that does not work, I will bring it to CSE, he is an engineer, a bergite, and a Mesan.

What bike is it ? Electric Start ? I have a leak but probably not from the same area. The source is always hard to determine due to wind and gravity. ?? Mine is from the o-ring on the starter which was repaired with gasket seal by the previous owner - grey stuff everywhere. I put my own sourced o-ring in and it held up for a while but my dealer now got me the correct one which I am going to fit. My experience with o-rings in general is that they are almost impossible to replace with one off the shelf.
 
I tried something that BOSS told me to do over the phone, as far as the left side cover goes.

Apply Wurth sealant case-side, then add the gasket on top, make sure it is evenly applied and the gasket well aligned. Make sure there is no sealant on top of the gasket. Wait a few minutes then put the cover and torque it.

According to him, doing this should allow removing the cover several times without replacing the gasket ($6.00 saving) and the Wurth sealant will help keep it in place and solid, and also solve any leaking issue.

So I did that tonight, I will refill with oil tomorrow night and let you know how it goes.

I also put the waterpump cover back on with no gasket ($3.00 saving), put instead a nice and even thin layer of Wurth sealant. I know this actually works because I did it yesterday.

That sealant is very easy to apply and also to wipe off excess right after torquing the covers. Also very easy to peel off when dry. It is not as rubbery as the Threebond, which can be a pain to chase if you lose a bead of it in the middle of the engine.
 
i've had the same sidecover gasket for over three seasons now froggy. recently you said you didn't know how i had the time to do all the tests so i presume you know that that costs money as well right?

i've had that cover off probably 60 times in three years, even if i fitted it and undid the cover thirty seconds later.

now you know how i save my money!

Alrighty, the bike runs very well now that I adjusted the valves. But it did require a few kicks to get it started after being laid on the side and worked on.

I put 1200cc of oil and I wonder if that is not what makes the bike leak oil from the weep hole, because it ended up stopping after 5 minutes.

I did not want to aggravate my neighbors riding up and down the street (they are tolerant, to a certain point), so I don't know, I'd have to take it to the trail and see.

I am sure the passage is not blocked, there is no silicone in there, I know: I blew through the holes. Soooo it may be that too much oil is in there and it's going thru the weep hole?

Is that possible?
 
if you have a slight tear in the seal you should get natural splash finding it's way out and therefore a stseady drip-drip, however, if you've over filled it then there is simply more of it!

i recommend 900cc and i know that you've seen it here froggy cos it's been mentioned several times!

1200cc is for a full engine rebuild from bone dry!

you definately have a seal gone and so get another and try again.

is it facing you (can you see the numbers?
are you going to get the special tool i mentioned to you?
have you cleaned the shaft up with some scotchbrite / scouring pad?
what is the condition of your shaft? you have an old bike now and you'll be wearing out things not even mentioned on the whole of UHE!!!
replace the little 'O' ring on the shaft.

I have not done any top end work, just left side for the moment.

I know the bike is old, I will ride it until it explodes, which can be 100 miles or 10,000 miles.

So far so good.
 
that's not the view we've trained you to take up!

that's very immature of you froggy!

i don't think any of us can take that! poor bobzilla, to think that even though he may get out of your warranty claim he will still be morally in the wrong!

poor bob!

David, one day this bike will cease to be. It will happen, ok?

Everything is finite.

It's my Zen approach to motorcycle maintenance.

So far, so good Karma.
 
I checked it with by Berg dealer on Tuesday morning, he said that if the oil is over full, then there is likely to be a slight weep, otherwise he advised that it was generally a normal (but occasional) occurrence.

My oil level is to the top 1/3 of the sight glass, (1000 ml of oil without filter change) so probably in the vicinity of 1100ml in the cases) and the weep only occurred after riding hard for long distances, not done it since.

hopefully wont do it again.
