Badbar88 Posted December 25, 2010 Report Share Posted December 25, 2010 I just recently got a 4mil dune port and it seems to build up case pressure and spit oil out of the vent tube. I checked to make sure I wasn't over filled and that the vent tube wasn't kinked. Any ideas? Quote Link to comment Share on other sites More sharing options...
patrickkomar Posted December 26, 2010 Report Share Posted December 26, 2010 witch vent, front or rear? I tip my shee up on my six pack rack when i wash it ( with a 6 over are it stands straight up and down) so i stuff a bolt in the rear vent to keep it from draining trans oil. I once forgot to pull the bolt and it spewed oil out the front vent. Is there a possibility there's a clog in the line or the inlet to the case? Try and give both vent lines a shot of air and see if you get air out of the fill hole. Quote Link to comment Share on other sites More sharing options...

locogato11283 Posted December 26, 2010 Report Share Posted December 26, 2010 Something is pressurizing the transmission area. I'd start looking at seals. Quote Link to comment Share on other sites More sharing options...
Badbar88 Posted December 26, 2010 Author Report Share Posted December 26, 2010 Thanks for the heads up. I'm hoping it's something in the vent tube clogging it up. It happened right after I got the motor together and it was a kink in the vent tube at the back vent. After about a day of riding it, it started to do it again once it got hot.

Theres pressure in the trans. Thats why it blowing out the hose. Quote Link to comment Share on other sites More sharing options...
Badbar88 Posted December 26, 2010 Author Report Share Posted December 26, 2010 I'll throw some new seals on it and hope it's good to go, thanks again guys. Quote Link to comment Share on other sites More sharing options...
Wicked ATV Posted December 26, 2010 Report Share Posted December 26, 2010 I'll throw some new seals on it and hope it's good to go, thanks again guys. Make sure you have all the breather line open. The one from the back of the motor, behind the water pump cover and where the T- together and go out to the front of the radiator is pinched between the tank or something. By the way right on BAD RELIGION ROCKS! Quote Link to comment Share on other sites More sharing options...
Darthwall Posted December 26, 2010 Report Share Posted December 26, 2010 when you put it together did you make sure and clean the cases really good? get rid of any oil on them? Quote Link to comment Share on other sites More sharing options...
