MotulMonsta Posted February 26, 2004 Report Share Posted February 26, 2004 Does anybody else have a problem with oil blowing out their tranny breathing vents? There are two, one in the back right below the rear uper engine mount and one below the water pump. I keep blowing oil out the one below the water pump and have yet to find the reason why. I'v rebuilt the motor twice even used Yamabond to seal the cases as per manufacture's instrutions...it still does it. I'm pretty shure it isn't crankcase blowby but I haven't tested yet.

fixitrod Posted February 26, 2004 Report Share Posted February 26, 2004 I had the same trouble. If you don't have a bad crank seal, then you are filling it to full. I filled it with the recommended amount and it would blow out on whoops. I now just fill it till it is on the cross hatches on the bottom of the dip stick... no more troubles !!!

MotulMonsta Posted February 26, 2004 Author Report Share Posted February 26, 2004 That's where I keep the level but I tried to seal up that front breather as the back should be enough to equlize the pressure. Nope I blew out the seal and pissed oil all over the ground. Now I got a diffrent setup hoplull it will drain back into the motor before it blows out. I'll see. I'm just wondering why that vent is there in the first place. It's got a rubber seal that goes to nothing like somthing should have been there. Nothing in the books about it. I don't know where the pressure came to blow that sealant out. Quote Link to comment Share on other sites More sharing options...
