V8s collector gaskets!

[slideways]

I have popped over here from the chimaera forum, to try and locate some copper gaskets for the collector on my manifolds which are v8s ones. They are mated to twin turbos so certainly not standard fitment.
I am eating my way through composite gasket material ones every week or two, admittedly they haven't got a fire ring but if I can source some copper ones they may seal better.



Cheers guys over to you

You mean the 3 bolt triangular jobs?
I got them from David Gerald but I think they were composite but did have the fire ring in the centre. They were the silver looking sandwich material.

The fire ring will help, cheers

If they're a simple flat gasket, one big hole and three little ones why not make some? this might not be quite right but plenty to choose from

I seem to remember they were dead cheap iro £3 each I think so hardly worth farting about!

Certainly isn't at that sort of price, unless the copper ones are no longer available!

I tried loads of places before I found out DG did them. Nothing anyone had for cars was anywhere near big enough - prob a commercial vehicle size or something.

Looks like a fascinating project, I'd like to see more of it. I got some solid head gaskets made by a chap called Mike Tanski and it's surprisingly cheap to do, but for a simple design like that you might just as well get a nibbler and cut your own out of sheet. Gasket problems seem to be quite common on turbo cars and I wonder whether it's related to the large temperature changes causing so much expansion that the bolts run out of stretch. I remember hearing that Land Rover used sleeves on some manifold bolts to give a longer stretch length to address problems like this, you might consider trying that.
