Gaskets Vs Gasket Glue

[shanef]

Hi all,

What i want to know is, is it necessary to put on new gaskets rather than using gasket glue? I've got the WHOLE Locknut gasket glue range. Parts i'll be doing it to is rocker covers, turbo to manifold gasket, exhuast gaskets, dump pipe to turbo gasket, turbo oil drain pipe gasket.

cheers

AFAIC if a gasket was originally used between the mating surfaces, it should be replaced with a gasket (if needed - rocker cover gaskets on RB engines are generally re-usable, but can go hard with age). I'm thinking particularly of paper gaskets. An exception might be if the mating surfaces are damaged, in which case I'd still use a new gasket but give it a bit of 'help' with a quality sealer (eg Hylomar).

Where a sealer was originally used (eg RB sump) I'd use a sealer (eg 3-Bond).

I'd never replace a gasket entirely with sealer except as a last resort (eg gasket NLA).
