The RH one already has the fixings broken, but the seller says is NOS !

Hello

These are being sold by darren in southampton - i remember buying these from MVS as ex-military stock!! (the total amount i brought weighed about one and a half tonnes!).

I can't see what you mean by the mountings being broken on the RH one, i have lost contact with darren over the years but if he says they are unused then that is what they will be!

good luck with the bidding and it will be interesting to see how much they go for!

They look ok to me... can't see anything amiss and I've got a couple lying around I just bought so it's easy to compare. Was wondering... anyone ever think of somehow protecting these manifolds to try to prevent cracking and general decay (in addition to fitting them with gaskets)? Can they be internally ceramic coated to keep them "cooler" in an attempt at minimising the hot/cold expansion cycles - any other hare-brained ideas? :roll:

Yes you can help by using gasket between manifold and head and I used stainless bolts as in theory the rate of expansion is similar to cast iron. so far they've survived.

I also found an engineering firm that was able to machine the faces of my spare set so that they were parallel. V awkward to do as the cast is very thin and springy. They had to make a jig to do it.

So if it's been done once it can be done again!

I was extremely lucky enough to have a pair of nos ones I bought ages ago.
Before I fitted them I had the faces milled flat but, as has been mentioned, the engineering company had to make a special jig first to hold them in place.
It wasn't cheap but I wanted to give them at least a fighting chance of lasting!
I also used metal gaskets and ss bolts and torqued the bolts up to the factory spec which is not that much.
Not sure if there is anything else humanly possible to do to stock ones to stop them cracking up.
The ones they replaced and which I took off to inspect whilst I was fitting a new ss exhaust were a maze of hairline cracks everywhere although surprisingly they were both still intact!
I've heard that Martin at Able's are in the process of manufacturing ss direct replacement manifolds although I'm not sure how far down the line they are or if they will fit the winch models whose winch cable pulley gets in the way.
In the fullness of time, it seems likely that there will be hardly any 101's left with stock manifolds and someone somewhere will find a solution, although at what cost?

Stainless manifolds are improving as it has taken a few versions to get it right. One man makes them so could be available to the Club subject to further investigation.

Does anyone know if stainless exhaust manifolds are now made?
