Good Sealant for Defender TD5 Rocker Cover

Does anyone know of a very very very good sealant that i can apply on my rocker cover to stop it from weaping.

I have fitted brand new allmakes4x4 seal to the rocker and it is still weeping just the tiniest bit.

I even applied some loctite copper engine sealant to the gasket.

Im considering trying the gasket just on its own without the silicone stuff.


please give me some suggestions and brand names.

RTV silicone etc etc

I am loosing the will to live with it haha

Degrease with brake cleaner then Small blob instant gasket in cam lobe corners and if you have excessive crank case pressure it will leak-been covered recently

I always use hylomar blue.
It's non setting and always done me well.
