Well i've found a stockist after sending an email to Germany and the response was very quick and professional so lets hope their gaskets are of the same standard..

Is that over here or Germany , i looked on the site but when i see the postage costs it wasnt worth it from Germany unless bulk ordering  :-\ Think you would be Guinea pig trialling them as no one else seems to have tested the longevity  :-\

Well Vauxhall quoted £114 of course cheaper on TC if i could join,so had a quote today from Motorcare Motor Factors ltd of £8 each now that maybe for a pair not quite sure and i have to wait until July to get them but no rush.As i said i emailed Germany who quickly got someone in the UK to email me with local suppliers,their main distributor in the UK is Mahle,these gaskets were recommended by one of our members as above.Obviously the Vauxhall ones aren't that great otherwise we wouldn't have all these problems and we'll find out i'm sure

I used either Loctite 518 (the red stuff), or a sealant similar to loctite 5980.
Eitherway, you can use 5980, it withstands oil and tepms up to 250°C.

Vauxhall/GM stuff is probably made by Heinkel (Loctite).

Keep us up to date. So far the pattern Cam cover gaskets have lasted anything from a few weeks to a few months, the exception being the ones that (I think) dbug is currently trialling.

I am curious why they are so prone to failure, and why buying the best is critical. As long as the breathers are clear they act only as an oil seal at no pressure, not a demanding role. Once the small breather is blocked they have to withstand crankcase pressure. Then you need the best gasket you can buy, and even that will fail eventually.

I reckon some garages (and some owners) fit new gaskets without clearing the breathers. They should fit GM gaskets! If the breathers are clear I reckon any gasket should do.

Very rarely do garages clean the breathers. They fail because they go hard and brittle. This seems to happen much more quickly on pattern gaskets.
