I've been waiting for the opportunity to install these copper rocker box gaskets, so after recently installing a fresh cylinder head, and re-torquing after 50 and 500 miles and all the rocker box removing and re-installing that goes along with it using normal gaskets, I thought it was time to cure this darn leaky rocker box problem once and for all, so after the last re torquing I put on the copper gaskets, after commandeering my wife' jewelry electric furnace, and annealing them as per installation instructions. With great anticipation I took my Super Rocket out for a 50 mile ride. It leaked much worse than the normal gaskets, at least with the regular ones it didn't leak for a while.
This was very disappointing, but I thought perhaps after everything had heated up and cooled down, I could check the tightness of all the rocker box bolts and nuts, and I did find that a couple of them could be snugged up a bit more, so I cleaned off all the oil. and took her out again today, about 25 miles. It still leaks just as bad, so I suppose I'll be going back to the normal gasket material.
Does anyone else have any positive experiences with the copper gaskets?
