Yeah i re-tightened the breather but it actually made it worse. The problem is the gasket. It's a little off at the holes. If i recall correctly, it's slightly too small so it bunches the gasket when you put the bolts through the holes. The holes need to be expanded which is not easy because they are small and the gasket is thin and there's not much room to the outside on the gasket for expanding. I optimistically thought it would flatten out when compressed and wouldn't be an issue. I also used some loctite sealant (forget which one of the top of my head, but it's red and thin). That did not work. I am hoping i can get get it off from the bottom, but there's like one bolt that might have a clearance issue with the gearbox.

Not sure why the oil is not returning. I have a temp oil pressure guage at the left rocker inlet. I'm getting pressure there. Maybe it's that i just can't see the return because the breather is constantly gushing over the return tube. Maybe that's a clue, i don't think the breather should be constantly doing that. I pulled the return hose and checked the tube that goes to the tank and that is clear. Next i plan to either kick it or start it to see if i get return at the hose that connects to that tube.

The gas line is the least of my problems at the moment. I have a temp gas tank on and will address the fuel line when i go to replace that

[QUOTE="TomU, post: 603827, member: 7984"] Yeah i re-tightened the breather but it actually made it worse. The problem is the gasket. It's a little off at the holes. If i recall correctly, it's slightly too small so it bunches the gasket when you put the bolts through the holes. The holes need to be expanded which is not easy because they are small and the gasket is thin and there's not much room to the outside on the gasket for expanding. I optimistically thought it would flatten out when compressed and wouldn't be an issue. I also used some loctite sealant (forget which one of the top of my head, but it's red and thin). That did not work. I am hoping i can get get it off from the bottom, but there's like one bolt that might have a clearance issue with the gearbox. Not sure why the oil is not returning.
