spfksfdk Posted February 4, 2009 Share Posted February 4, 2009 I am still trying to correct a problem with the red warning light coming on, long story... Now I've got an oil leak. It seems to be coming from the banjo on the lower end of the big oil pipe on the left hand side of the bike. I have just replaced to two washers and tried as best I could to ensure all surfaces were clean, but it still leaks!!!! Any ideas? Link to comment
Boffin Posted February 4, 2009 Share Posted February 4, 2009 This pipe is the oil-cooler return line, the two alluminum (or sometimes copper) sealing washers should do the trick if all is clean and level. What I found on my bike recently however, was considerable corrosion where the pipe is strapped to the engine front casing. As this pipe is powder coated, a small crack can allow corrosion to spread down under the coating, effectively lifting it free. This means that any small leak from part-way down the pipe from corrosion would be conducted down to the banjo, giving the appearance that the leak is coming from there. Andy Link to comment
spfksfdk Posted February 4, 2009 Author Share Posted February 4, 2009 Thanks Boffin, I've just been outside and taken the side-panel off to get a better look. I removed the banjo and cleaned it up, like you said the black power coat just flaked off leaving a rusty surface. I cleaned and cleaned again then put it all back with some blue Hylema sealer. I ran it for about 15min and couldn't see a leak like I did last time, although I am not convinced I have fully sealed it. Guess I'll have to wait till I get to work tomorrow and see how much oil is left :-) Link to comment
bmwdenk Posted February 5, 2009 Share Posted February 5, 2009 I'm really surprized that you already have a rusty pipe. There is quit a bit of testing on the pipes from any supplier before they are approved to be used. I work for BMW (autos) and corrosive that is done is pretty extensive. The normal wear is quite better then 8 years. I'm glad to see that you got the leak stopped hopefully. If it still leaks you may want to check the sealing surface on the banjo blt and the cooler. Small scratches has caused similar leaks from what I've seen. Good Luck Link to comment
spfksfdk Posted February 11, 2009 Author Share Posted February 11, 2009 Oil leak seems to be fixed. The old seal was almost corroded away at one point, this may have been where it was leaking? Link to comment
Tony_K Posted February 11, 2009 Share Posted February 11, 2009 Man, My sympathies for you chaps in the UK. Seems everything you have there succumbs to the ambient environment via corrosion. For a short time I had a 1962 Austin Mini that was imported into the states (specifically CA) in 62! Rust free! (I regret the sale) Although I'm sure in that short period of time from build date to boat the English elements were trying to get to it! Link to comment
