Does anybody know where i could get a Head Gasket for my S6. The engine is being rebuilt at the moment but there is no sign of head gaskets, i have called evry single dealer and specialist i can find,the factory haven't got any and dont know when there will be any available. The engine is all assembled and ready to go bar the head gasket for final assembly any help would be appreciated
Try Justin Baker, he had a headgasket for sale recently?

Here's a link for the dimensions. I drew this up a couple of months ago, and incorporated the water way revisions.

My gasket has now gone, sorry I should have removed it from the classifieds. I think Paul at Austec has now had some made, so there should be stock with him.
If you have the specs for the gasket then Ferriday could probably make them for you, they did my copper decompression plates nice and cheap and quick. They also do composite gaskets, but I imagine that copper would be better if that's what the originals are - I guess copper would also be a fair bit quicker and cheaper.

I checked with Dave this morning, and he confirmed that their head gasket is suitable for the standard engine.
He has stock, and is happy to help !
Redrose, I think Daves got 2 types, one is modified to Al Melling's original speed 6 spec for their own modded head design, and then there are ones which are direct replacements for stock production engine.
But the stock-replacement ones arent in stock cos someone already asked me if I knew anyone and I asked Dave, but he is ordering a few on Monday, so it would be advised to get an order in on early Monday before he passes the order to his subcontractor.
Craft are stock-piling now, for both their own custom internals and stock replacement internals, in a week or so I think everyone will be able to buy bits direct from them at their company site www.tvrcraft.com
Its funny though, god knows why factory stock is soooo low????? whats going on?

The Speed6 gaskets are not cheap to make as one offs!
Some of these companies have minimum order levels imposed!
Which is why a number of people are trying to source them from someone who may have them in stock already.

Ferriday have done one-off gaskets for me in the past with a quick turnaround for a reasonable price. No doubt you get get a better unit price for a batch, but that's no help for people who only want one. If you can spec the gasket adequately, I think a one-off copper gasket would be economically feasible. I expect that composite gasket would cost a lot more, but if it's the difference between having an engine this year or next then an extra hundred quid on the bill probably isn't the deciding factor.

True enough. Money is just money at the end of the day. Nothings impossible. I dont personally know much about the Speed 6 gasket, but do you think TVR have asked their suppliers not to supply anyone else but them, like the AP clutch situation? Most likely, and is it easy enough to make a copy from an existing gasket? or are proper CAD drawings required? I thought the Speed 6 gaskets are pressurized copper or something? that would bump the costs up considerably compared to standard bog copper ones? :scratch:
Pressurised copper, wassat?
I think the basic options are solid or composite. For solid you have the choice of copper or aluminium - aluminium would be cheaper but might make sense if you have an all-alloy engine which is not highly stressed. Copper is slightly more expensive but effectively indestructable.
I don't think you can necessarily replace a composite gasket with a solid one, with a composite gasket the fire rings and seal inserts determine how the clamping loads are distributed over the sealing face and I expect that this would change dramatically with a solid gasket. But if the original gasket was solid (as somebody suggested it was with this engine) then as far as I can see all you need is the thickness and exact size/shape of the various holes. I seem to remember somebody else has already created a CAD model for a S6 head gasket, but I don't suppose it would be particularly difficult to measure up the old one. Ferriday didn't need a spec from me because they already had a model for the gasket I needed, but they weren't going to charge much to generate the model for me.

Here's the data www.racecarlivery.co.uk/SP6.DXF It can be converted to any flavour of CAD package if anyone needs it.

Sweet!!!! Justin can you model anything? how much do you charge?
justinbaker said:
Ash Hi, e-mail through what you need, I probably wont charge, if it helps your project move forward.
Thanks Justin!
Dont need anything to do with phoenix engine stuff because Allistar (craft's head engineer) does all that stuff anyway.
But... I've got some 'sound' business ideas! Nothing to do with cars but when I get my head together, I'll drop you a line, and catch up on those missed beers!
