Oil seepage from filler

[mikefox]

Has anyone else had trouble with oil seepage from the gasket at the bottom of the filler neck?  Aslo, are all newer filler necks plastic?  I seem to remember the older ones being metal.

Thanks,

My 20c has a metal 1, and it has seeped in the past. Mechanic tightened it and safety wired and and voila, problem solved.

Its a common problem. Glue it in and then pull the safety wire tight. Holding the filler neck while unscrewing the dipstick will help alot.

Thats just a thin paper gasket and it leaks when the tube backs off from removing the dipstick.

 

We fixed this problem by replacing that gasket with a thin o-ring and then dogged the tube down tight and safety wired it. Its a permanent fix.

Mine leaks.  Good suggestions.
