Breather cover keeps leaking

[bakirkwold]

I am on my second breather cover gasket. And its still leaking? Any ideas? Could there be a pressure build up or something?

[Agemax]

is the breather cover hole blocked. is it leaking from the breather hole or the cover itself?

Is this out the breather hose itself into the airbox or leaking at the gasket surface like Agemax asked?

If it's out the breather hose, quite normal. With my custom catch tank I have caught a little blow by now and it's no big deal and when I stop I occasionally get some smoky looking vapour come out the breather filter and it disappears very quickly.

If it's leaking at the gasket surface, are you using a genuine gasket? I'm still using my dodgy Athena one and it weeps non stop. It will be replaced with a genuine one at the next service.

It's also possible that the breather cover is warped so put it on a flat surface and ensure it doesn't rock.

Also, check the wire mesh in the breather cover and top of the valve cover to ensure there's four separate pieces in there and make sure they're not caked in gunk. A quick soak in kerosene should take care of that no sweat.
