Help me sort out my head?????

[kiwiz]

Steve,
I recently rebulit the top end of my J installing a Wiseco big bore kit. I an earlier thread you sorted out my confusion on whether I retained the various O rings when using this gasket and you correctly said "no"

However Since the engine has been assembled there has been a fine mist of oil around the bore which I originally thougth was just a leak from a cam plug but it seems to be more general than that, around the cylinder head joint. Given that the head is properly torqued (well the 12mm anyway, the 2 end 6mm bolts I think have BU***d threads). Could the leakage be that the 2 6mm bolts are not tightened down or for some other reason? One thing I note is that you seem to suggest filling in the cam tunnel O ring groove. I have not done so. Could that be the problem?

Hello Kiwiz, yes the camchain tunnel is very close to the cylinder bores so I would expect this to be the problem, the 6mm bolts at the end do very little, 2 6mm bolts into alloy will have very little impact compared to 12 x 10mm steel studs torqued to 35ft lb, Regards, Steve
