Rocker Cover Gasket - won't seal

[Nick H]

Hi Guys, I have been using this great site for a while to get really helpful info and have also acquired one of Mustang's valve shim tools which was brilliant at getting shims out recently.  But, I have been putting everything back together and I can't seem to get the rocker cover gasket to seal properly.  It leaks a little oil out of the left side.  I didn't put a new gsaket on as the are nearly £30, but maybe I should have done.

Any words of wisdom would be appreciated.

Thanks, Nick

did you try using alittle silicone sealant on the gasket where the leak is .

Triumph recommends using sealant in and on the 4 camshaft areas as well as the plug holes and 4 corners

me , I don't bother as long as the rubber gasket is in good shape . and haven't had one leak yet (cursed myself now)

also over tightening the valve cover bolts can produce a leak also , they only need to be 7 nm IIRC
