hi i have a 1954 devon van 1200cc the engine had parts missing when i got it which have been replaced together with head rebuild for unleaded / crank regrind / block rebore all surfaces ground flat on rebuilding it all together the new all copper head gasket leaks all the head studs and nuts were replaced for new the head was fitted with no sealant the first time and head gasket cement the second time although the leak is minimal should i take it apart again / do you have to anneal a solid copper gasket the second time ihad it running until hot then done up the head nuts to 40 lb it still leaks HELP cheers tom

Hi Dave thanks for the reply I did take the head off again and annealed the solid copper gasket and refitted it my problem is very strange you can see small bubbles at the head joint nearest the bulkhead on the spark plug side I have checked cylinder compression all four are good and very close to each other after 1000 miles the engine has lost no oil or water starts on the button and drives ok my only mistake seems to be that I torqued the nuts down when hot if I have to take the head off again I will follow your advice to the letter. Thanks tom
