ignition cover leak help?

[volcomskater77]

so we got the bike to fire AND RUN today. woot! but while it was running, oil was pouring out of the points cover, onto the fins, and onto the exhaust wrap. causing it to smoke. a lot. like way more than fresh exhaust wrap should. i took off the cover, ad leveled it out with emery cloth. tried it again, and the same thing happened. but hey, im glad its only leaking there, and not anywhere else after the full rebuild! lol heres some pics.

any idears as to what it could be or how to fix it? (aside from usig RTV? gasket is brand new.

I have the same oil leak on mine. there is an oil seal behind the points and the advance unit, on the cam shaft end

Arclight88 gave me the link # 11
No oil should enter into the points cover, so replacing the cover gasket is usless
hope that helped!!
Just thought that maybe coming from the valve cover also, but if its coming out of the points cover, most likely the cam oil seal

Take the cover off and clean those rubber knobby things then look for oil maybe.
They are the rocker arm plugs in the points housing. part 15 here

Good call!! I forgot about those little buggers!

the points cover supposed to leak as it has a cut out under neath ( well mine does) stops condensation I suppose and it seems to also tell you the cam seal is leaking too

 

[volcomskater77]

sweet..... now i gotta take apart the top end. right after i got it running decent lol
thanks for the help guys. ill look into it this weekend. logan, that link doesnt work

 

[logan]

sorry about the link, I had just asked a similar question a week or so ago, the link could be found there

 

[drewpy]

don't need to totally strip it.

take out the contacts/triggers and you can see the cam seal.

just loosen the cam cover and draw off the seal. replace and tighten back the cam cover.

Page 5 in the garage, oil seal help, started by me, there is a link to the seal. they say its discontinued but if you search i bet you could find it. sorry thats the best I could do! I did end up using some RTV on mine, also on the small rubber buggers aswell, worked like a charm!( Im cheap, and have no acsess to those kind of parts, I live in the middle of nowhere!)

 

[branson]

Too much work hunting dead subjects five pages back for a seal. Ill just ninja it

You just asked for a #, and I told you where to find it... Its not hard to scrol and click!

1980 you say? Looks like the link from Logan says 93102-23190 which you found. You can plug that part # in search-engine and find http://www.boats.net/parts/detail/yamaha/Y-93102-23190-00.html

Also search this forum for good place to find the right "seal kit", might be a good idea to have other seals for possible leaks in future. one on ebay for $35
crank case seals, clutch pushrod seal, kickstart seal, shift-shaft seal and tachometer seal

yeah i fail at using search. sometimes things pop up and sometimes they dont find anything. thanks for the heads up.
