dirtplay1975 Posted February 28, 2007 Report Share Posted February 28, 2007 I am at a loss as to why the Banshee a friend just bought is blowing transmission oil out of the vent hose. This thing dumps quite alot of fluid out all over everythign when you ride it. I removed the clutch over tonight and inspected everything inside, crank seal looks good, the vent hoses are not plugged, and nothing is apparent to why it would have been doing so. I also re routed the hose back to where it should have been and of course it has new trans oil now, but it was too late to ride it without pissing off the neighbors so I only hope this fixed it. If anyone has had this problem or have a solution I would appreciate the help. Quote Link to comment Share on other sites More sharing options...

What ever was used for a gasket between the upper and lower case halves is no longer sealing. Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted February 28, 2007 Report Share Posted February 28, 2007 If you over fill the oil it will do it too. Quote Link to comment Share on other sites More sharing options...
pokeatyou2 Posted February 28, 2007 Report Share Posted February 28, 2007 If you over fill the oil it will do it too. thats what i was thinkinsg if you keeped the oil that came out of it measure it to see if there is still more that 1.5L if so add that to the oil that was blowing out of it and that equals over full.

FireHead Posted February 28, 2007 Report Share Posted February 28, 2007 If you over fill the oil it will do it too. Good call. I didn't think of the oil heating up, expanding, and thus overflowing. :thumbsup: Quote Link to comment Share on other sites More sharing options...
woodro77 Posted February 28, 2007 Report Share Posted February 28, 2007 If you over fill the oil it will do it too. it will come out until the oil level is correct , so if you put the correct oil level in and it still pisses out you know the crank case is getting pressurized and its a bad seal Quote Link to comment Share on other sites More sharing options...

350shee Posted February 28, 2007 Report Share Posted February 28, 2007 I would bet on a bad crank seal. Quote Link to comment Share on other sites More sharing options...
FireHead Posted February 28, 2007 Report Share Posted February 28, 2007 I creatively routed my vent lines one time, which turned out to cause a similair situation. It's probably not the case as what I came up with was something pretty far from OEM routing, but I thought I'd throw that out there. :thumbsup: Quote Link to comment Share on other sites More sharing options...
dirtplay1975 Posted February 28, 2007 Author Report Share Posted February 28, 2007 ya the vent lines were routed pretty weird, someone just brung them to the outside to clear the boost bottle I guess, but I fixed that last night, with my friend just buying it we had no clue what oil was used so it got changed and belray put in when the clutch cover was taken off for inspection. I am kinda hopefull it will be fixed now, but if its nto I guess I will pull the motor and slpit cases, drop in some crank seals and get it together again so it will make it to little sahara sat with the rest of us. Guess thats what I get for having friends that dont know much about working on stuff :yelrotflmao: Quote Link to comment Share on other sites More sharing options...

Guess thats what I get for having friends that dont know much about working on stuff :yelrotflmao: My vent line routing situation that caused me problems had to do with running the lines straight out of the case and down. Between the lockup clutch assembly and the use of some heavy oil, I never gave the oil a chance to de-gas and thus it was pumping itself out the lines. Of course, it only did it when the engine was hot to further compound the problem. It took me a couple iterations before I sorted out what was going on.
