<p class="MsoNormal"><span style="mso-fareast-language:EN-US">Fred,
I can add to Mikeâ??s comment as it is my BT7 we were working
on. We had used the head gasket that came with the head set
supplied by MOSS. As the engine warmed up I had coolant
leaking out almost the entire length of the block/head seam,
and coming up through several of the head studs. This was
not a localized leak and I would describe it as complete
failure of the gasket as far as the coolant passages are
concerned. There was no evidence of oil leakage, but I
think I am correct in saying that all but one of the oil
passages between the head and block are for drainage back
down to the sump and thus not under pressure. There was no
water/steam in the exhaust and the car fired evenly (it
sounded great!) and no coolant in the cylinders after we
removed the head, so it looks like just the coolant was
leaking. However remember the motor had been running for
only about 15 min total over several gentle warm/cool
cycles. FYI, I use a correct 7 lb rad cap.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="mso-fareast-language:EN-US">On
removing the head we could find no evidence of any problem.Â
The gasket looked fine, so we really do not know the cause
of the failure. This was a complete rebuild so both the
head and the block faces were machined.<o:p></o:p></span></p>
<p class="MsoNormal"><span
style="mso-fareast-language:EN-US"><o:p>Â </o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US">I
ordered a â??Premiumâ?? head gasket which was supplied by A-H
Spares via Healey Autofarm here in Ontario (thanks Amanda
for the quick service). My understanding (i.e., I donâ??t
know for a fact) is that A-H Spares has these Premium
gaskets made and supplies them to others, including MOSS.Â
It is pricey and the prices vary, so shop around. Neither
Mike nor I could discern any visible difference between the
â??regularâ?? head gasket and the Premium one (except for the
part number), although we did not measure the thickness and
the material that is sandwiched between the copper/steel
outer layers may well be a different material or
thickness.<o:p></o:p></span></p>

dressing in other rebuilds so although we discussed it we
did not apply any. Curiously, the MOSS tech expert finally
responded to my request to discuss the issue (about a 3 week

lifted the head with manifolds once before so knew it could
be done, but this was a BT7 and I am unfamiliar with the
details of a BJ7 engine bay and whether there are any added
complications. I suggest if you lift it with the manifolds,
rest the head on top of the studs when you lift it and
remove the two intake manifold drain pipes, and do the same
in reverse (as they are a real bugger to get on later) and
you would have to lift the head very high when removing if
