i have an early 1984 ironhead and im getting a pretty bad oil leak out of (what i think is) my transmission vent tube right under my starter. I also just replaced the headgaskets because the back cylinder was leaking, cleaned it all up and put new copper gaskets in and it is still leaking. Too much oil pressure? what would cause this? im stumped...any help would be greatly appreciated.

the primary oil is where it should be. its motor oil that is coming out of that vent tube. tomorrow im gonna check the ball valve in the oil pump. i have a feeling that oil is sitting in the crankcase that isnt getting circulated and with the added pressure in there its finding whatever way it can to get out.

Oil is building up in the lower end....As you said....But if this was the case...You would also be seeing oil coming out the vent at the gen...

I wonder....
On that year model the cam cover has a one way check valve pressed into the cam cover....
My wonder is what would happen if for some reason that would not allow pressure to escape....???

there is some oil coming out of the gen vent also, but not nearly as much as the trans vent. there is a lot of pressure coming out of the gen vent, seems like too much pressure to me...but then again i dont remember what it was like last fall and i dont now anybody around here with an ironhead to make a comparison...
