stock valve cover question

[jlat]

hello; On the drivers side VC I know Kirban use to or still does sell a thicker rubber like material to tghten up the breather filler tube when using a aftermarket tube. You know the one you can put a filter on. Mine has lost it's tightness and the tube is loose now causing engine oil to find it's way out is making a mess.
Is there a better setup to stop this problem once and for all.?

You can tighten the tabs with a pair of pliers. might help some.

hello; Looking at the machined alum. filler tube part of the problem if some of the alum. on both tabs have worn groove like areas causing part of the problem. I guess from vibration as its been on a while. Maybe it's time for a new tube? Do they still sell them?
