I finally got my pluming all finished yesterday,Head vents and Trans vent into a catch can with a vent and filter. Bad idea I blew the cover off of the oil tank going down the freeway . What a mess that made. I maybe only lost a half a quart or less. I didn't know what happened at first but I lost the rear brake so I pulled over. Yeah it was oiled up pretty good. I guess I will be re-routing the trans vent before the next ride. Is anyone running trans vent into the same can as the head vents? | ||

Has your can got a breather itself? | ||

This can (and often does) happen if you forget to check the oil with the engine warm, and so add too much. Too much oil, pressurize the system, blow the cap, try not to wreck... It's kind of a right of passage. Check the oil after your ride, or let it warm up a few min, then check it. Oil will sump down into the engine case and give you a false low reading. Have a turkey baster or large syringe handy, start it with the cap off, if it gets close to the top draw some oil off til it's below the halfway mark on the dip stick. Once you figure the level your bike likes to be at you will stop worrying about the oil. Keep adding and you'll just keep blowing off the extra. 'Course, if you are loosing oil out the trans vent tube you've prolly got a bad crank seal. (Message edited by littlebuggles on April 22, 2013) | ||

What he said.  | ||

No oil from crank vent,no oil from the breathers. Yes vented can. Oil checked with the engine running. I will add a T fitting and another vent filter on the trans vent line,that should end the issue. | ||

my S1 has XB rockers. PCV lines collect into one brass nipple, the trans vent into another brass nipple and the vent line in the last brass nipple. All three nipples are screwed to the lid of a 2 or 3 ounce plastic spice jar. the filter line should be higher than the can itself. the catch can itself hangs vertically alongside the oil lines leading to the oil bag. I use a loose fit zip tie that I slide down for emptying the can. The vent is under the license plate. | ||

I did the trick on my x1 right after I did my first oil change and didnt know about the board here...back in 99 I guess....and all I could think of was ///"what the ^&$?"..three buells and only done that trick once! man what a mess though!! | ||

My S1W blew the top off the oil tank when I did my 1st oil change and cranked it with the seat off. I've had an oil stain on the ceiling of my garage ever since. I'm planning to set up my catch can this evening as I put on the new exhaust. | ||

TOO MUCH OIL IN OIL TANK !!! OIL SYSTEM Class 101, just PM me for a copy !!! | ||

Can too much oil pressure the system and contribute to crank seal failure? | ||

Glad I wasn't the only one.....measure when fully warmed up!!!!! | ||

O.K. That may be it was like 91 degrees yesterday. Made a huge mess. I cleaned it up though. Lucky, if you want to call it that I was only a few blocks from home. | ||

AZB, sounds like you've got things figured out then? You seem to have a good handle on what you're doing, so maybe your venting was the problem... seems odd to me, but, I'm not a mechanic and have learned as I went along... as I and my bike age I've had to pick up new skills so I'll say no more on the matter. Anyway, it's good that you weren't hurt, and both you and that nicely restored X1 made it home safe! Bengny, Early seals are not a great design design, and the rubber hardens up over the years. If you have a tube framed Buell with the original seal it is probably bad. That said, if the seal is hardened but intact, I can imagine a scenario where "too much oil pressure in the system" as you said, which might cause the old and hard seal to crack or leak worse that it previously did (barely noticeable seep from engine to primary). I didn't think my seal was bad but checked it because I had the clutch out, the seal was garbage - while still intact it crumbled as I checked then removed it, so it would have given up at some terribly inconvenient time. -Mike | ||

I don't think that too much oil in the system increases oil pressure. It just leaves not enough room in the oil bag for expansion. Pressure is created by the oil pump, the pump doesn't know how much oil you put in. | ||

The transmission vent should remain bone dry if the crank seal is doing its job and the oil level is proper in the tank. Consider yourself very lucky it did not happen on highway while doing 80 mph. Oil on rear tire is my worst nightmare and I check that at every stop light after reading stories like this. |
