I was recently advised by our supplier that the manufacturer (the only one known) of A40 head gaskets, has advised that that the tooling for making these is beyond its serviceable use and they will therefore not supply any more. They also declined to make new tooling.
Together with the supplier we have now commissioned new tooling and an initial order from an overseas supplier. We were unable to find any alternative to this for a copper and board gasket. This has resulted in a considerable investment by the club.
The price of the copper and board gasket (1A180) from 1st November 2016 will be £30 each to club members.
A number of members have written about the success they have had with solid copper head gaskets.
We have now also had a small batch of these made. They are made from soft copper and are ready to fit. I am also advised that they can be reused after removing from the engine provided that they are annealed before refitting. They have been made by a water jet cutting process so are accurate and have nice clean edges.
It may be possible to torque these down higher value than the normal 40ft/lb value, say 5 to 10 ft/lb more. However, if doing this, then I would highly recommend fitting new studs and nuts.
The price of the solid copper gasket 1A180SC is £35 each to club members and they are available for immediate dispatch
