Speed Six documentation
Discussion
It’s probably something for Steve Heath here, as this is his territory, but I was wondering if there would be any interest in compiling a basic manual for the speed six. There are many PH people that know quite a bit about these engines now and having some form of detail to this engine would benefit all Speed six owners. I would be happy to help out producing drawings and assembly illustrations.
Below; TVR SPEED SIX HEAD GASKET
www.racecarlivery.co.uk/SP6.DXF
Research, with part numbers/modifications known at component level and document it with accurate drawings showing the difference.
Obtaining any information would be good, maybe somewhere the CAD drawings and models exist for this engine that could be obtained.
I don’t mean to produce merchandise for profiteering, but to share and shed light onto this grey area for a little knowledge of what to expect from our engines.
I am still after a 3D scanner to assist with my own projects, so if anyone has one tucked in the back of their office not being used please give me a call. It would help with SP6 documentation too

......? The head gasket reminds me of the Rover SD1 engine for some reason.
Interesting photos, never seen one in bits. It occurs to me there are a hell of a lot of things to go wrong even before you even get to what goes on in the head. Not really the sort of engine you could rebuild properly without some assembly tech info to hand.
Good luck with your quest for info, can't see anyone(eg factory/dealers) wanting to share it though.

Can someone who knows explain how the bottom chain is adjusted, can't see how you can?
Also, I hope I am wrong but that isn't the water pump top right is it?
What is the bottom chain for ?
It looks short enough not to really need adjustment / lash.
The only thing that really needs accurate setup must be the crank to cams..
The chains look really heavy duty (duplex) - that's good

The bottom chain's can't be adjusted. No you are not wrong that is the water/oil pumps!

So, when the water pump bearings go, which they will and the seal starts to leak coolant, where does it go?

That was a question of mine to the dealer when I was taking the pictures. I guess the answer is when your oil becomes emulsified and rising in level you know there is a problem!

I would suggest that on an engine that knocks out followers/cams for a laugh it will be game over long before it gets noticed by an unlucky owner.
Without wishing to start a S6 slanging match(only my opinion) it would seem this engine was never designed to give the kind of service expected of a road car. It seems there are an awful lot of design features here waiting to bite someone in the @rse irrespective of how well it is looked after or treated.

Nick Elliott sent through a picture of his head gasket, and I compared this with the new one. It shows just how important it is to know what revisions have taken place.

So does this prove then that TVR have modified the block and head ?
btw which is the driver side of the gasket ? I wondering as I think I read that one of the issues was lack of cooling for the part of the engine tucked under the windscreen.
Cheers,
Andy.
just wondering how the oil circulates.
scavange pump comes out LHS bottom in pic (red plug) to resevior.
oil pump seems to have a straight in and out at the bottom RHS pic
as I remember the filter is on the block just behind the altenator.
where does it go from the "out" of the pump and where does the filter come into it
it's too cold to take the bonnet off today
Considering fitting an Oil pre oiler thingy

Its good of him to get back to me, and do appreciate the response.

Hello Justin,
Yes we do have drawings of the speed six engine but unfortunately it is not company policy to release drawings because we own the design rights to the engine and we don't want them to be in the public domain. I hope you can understand this.
Kind regards
