GT3 Exh Manifold
Discussion
Hi Guys
I've just purchased a GT3 with a crack in the exh manifold. I've done some searching but haven't found much recent info on this.
Does anyone know where replacements are available from? Are there any that are expected to last the life of the car or are they still considered service items? What's the pricing on replacements these days?
I'm a fairly competent hobby mechanic but exhausts do scare me simply because of how likely it is to shear a stud. Has anyone done this job themselves? I've heard that either pure acetone or acetone mixed with a bit of ATF works very well on seized bolts. If I was to apply several coats to all of the nuts and bolts several times over a day (and then leave overnight), would I still be likely to shear anything?
Cheers

I've just seen a kit that comes with new studs, nuts etc. Just wondering if it would be best to soak everything in plusgas a few times over a 24 hour period (trying to get it into the stud thread) and then going straight for a double nut extraction without trying to remove the original nut. Then in with the new studs with high temp copper anti-seize? Is there room on the threads and area surrounding the studs to do this? or perhaps just get straight in there with a nut splitter?
Lots of info out there on cracked manifolds.
Because after 80K miles or so, they just--- crack.

I have one of these on my 2.2 Esprit and it's a nice, well built piece of work.

Righto. The Alunox manifold is £1,150 + VAT or £1,000 if 10 people get into the group buy. It includes all the gaskets, new studs, nuts etc required but I'd have to do the work myself.
Fast road conversions would make one out of mild steel and fit it for around £800 with a lifetime warranty. I'm not sure whether I'd have to supply new gaskets etc.
I've heard good things about the Alunox manifold but that's quite a price difference. Anyone got any thoughts? There seems to be a bit of debate about mild steel vs SS.
