What's the service life of the 24v rocker gaskets? Mine were replaced 2yrs ago and they've been leaking for nearly a year now
I don't know, and it seems no-one else does either (or maybe it's a secret...).
My TS engine developed a premature minor cam cover leak after maybe a year or so (from the gasket being new). It's not the same specific application, but it's probably a similar style of rubber gasket (?). Anyway, I stopped the leak by removing the gasket and painting it (and the grooves etc in which it sits) with a non hardening gasket sealant, in this case 'Aviation Gasket No3' (one of my favourites). Leaking stopped.
Regards,
John.
I am aware of Shelf life, as distinct to Service life requirements and my guess is that Service Life is subject to many factors that would attribute to premature failure and as such car warranty periods is a good rule of thumb (3 years or 60K). As John indicated to get the best possible result it is imperative that the mating surfaces are properly cleaned and the use of recommended sealing products only be used. For those interested I have attached a link to a paper on the study on Service life of rubber products.

If fitted properly they should bloody well last longer than 12 months!
As mentioned above, if the mating surface is not cleaned properly brand new ones will leak.
Thanks everyone, so if I was to remove the existing gasket thoroughly clean the area and gasket and refit them using a recommended sealant it should work?
I see no reason why not.
