After several weeks of gathering info, service manuals(Thanks Ratbuell), parts, borrowed tools and lifts, and some bloody knuckles, I changed my own rocker box gaskets. From an earlier thread, I THOUGHT I was dumping oil from the secondary breather, but NOOOO... the vent for the tranny was plumbed into the same breather and this is where the oil is coming from. You guys have been great so far...What is my next line of attack? Thanks, Michael | ||

I had the SAME problem THIS weekend on my 99X1. I treated it like i did my 98 S1, Installed a breather filter and re-routed the line. I think you can also do a catch can fix as well.. but I like the looks of the breather filter. Matt. | ||

I don't know what it's called in english. But it could have something to do with your crank return ring? | ||

I think Buellgekk has it right - check the oil level in your primary. It'll spew out the vent if too high, and it can get high if the crank seal is failing. | ||

I think gekk was trying to it's the crank seal. Oil is leaking from the crankcase into the primary/transmission case. The excess oil blows out of the transmission vent line. Change that seal. You can add a little filter on the trans vent line to keep debris out, but a catch-can isn't necessary if everything is working properly. | ||

Yes that's the one! I also heard that you have to install this seal in the opposite than the manual describes. Because of the pressure. | ||

Thanks guys!! Any special tools etc. needed to do this or is this a stealership type of repair? The rocker box gasket change was my first attempt at home repairs and successful also. Thanks again. KV search is limited as to the tools part but helpful other wise. Michael | ||

It could be that you just overfilled the trans as it takes only 3/4 quart to get it to bottom of clutch basket. More than that and it will spew when hot. If it is the seal check the knowledge vault as this has been well documented. | ||

If there is more oil than you put in the primary?Your crank seal is bad.oil is coming from eng over filling prime,Then out breather tube.Or above | ||

I haven't had to add to the primary since April(3000 miles ago) I have resolved myself to the fact that it is crank seal. Anybody have crank seal tool that they could lend me? Thanks Michael | ||

I did mine without it... BUT, I would recommend using the tool if you can get your hands on it... Chase | ||

M2, I just replaced the seal , its called the sprocket shaft oil seal. You'll need the kent moore tool described here a 1-1/8 socket (engine sprocket nut), a 13/16 socket (mainshaft nut, which is REVERSE THREAD), and a big arse (technically speaking) breaker bar, a pair of circlip pliers helps a lot. The engine sprocket nut has 190 ft-lbs of torque + red loctite. It takes some work, i ended up using an air wrench, but that may cause damage to the magnets inside the sprocket (it also serves as 1/2 the alternator). You'll also need the stuff (gasket/oil seal) you'd normally use when pulling the primary cover The seal fits just as described in the manual or in Henrik's post from above. The tool is cheap, 17.00 from Andy at appleton you'll also need a 1" length of 1" diameter pipe to get the seal in place, again Henrik did a great job showing how this is done. The jobs actually not much more than pulling the primary when you get into it. It just looks like there is a lot to do. The scariest part was when I pulled the old seal which had a metal casing and I saw the new seal which is all rubber. I thought I shredded something important getting the old seal out. Just a new part, search for sprocket shaft oil seal, you'll see I wasn't the first to fall into that trap  |
