[Bellerophon]

I said at the start of all this when Eric first brought up the subject that
all the people selling Bristol cylinder head gaskets are selling the same
ones which the German BMW club had manufactured some time ago to fit BMW
engines. These are far easier to fit and are better than the old steel
corrotrue type which even the works had trouble with on their racing engines.
There does not now appear to be any other types available that I know of, so
one just has to add the extra hole if it is being fitted to a Bristol engine.

While here I would like to put those people right who think that because a
2 litre Bristol radiator does not have a pressurised cap (the Bristol cap
is made by Marstons) the system is not pressurised, they are wrong. If you
look you will see a boss on top of the radiator with a copper pipe running
to the bottom of the radiator, if you remove the plug on top of the boss you
will find a bronze ball and spring underneath to give the correct water
pressure.
My regards,
Bellerophon
