Evening all
Well after 20 years of having exceedingly hot noxious gases pumped down the inside and water and road dirt thrown at the outside my manifold pipes have worn as thin as one of my excuses to the missus after a boozy night out with the lads smile
My friendly mot man overlooked The slight blow earlier this year but I'm aware that every time I go for a drive is slightly worse each time.
Unfortunately having made a very large and potentially ruinous financial commitment earlier this year which must take priority (she says) grumpy I'm not in the position to purchase some of ACT's nice shiny stainless replacements frown
To that end I'm wondering if any of you fine gentlemen would have secreted in your garage or shed a set of serviceable manifolds that you may consider parting with for an appropriate amount of beer tokens??
They don't have to be great - just need keep the exhaust gases in the right place ( unlike my current set) and keep the mot man happy
Please pm me if you can help
Many thanks
Ron

Glen Wilson fitted new manifolds to his SEAC last year so he may well have an old set that need patching?? He also split an older 350i a few years back so again may have some spares knocking about. He's on both of the Facebook Wedge forums so drop him a message.

I have a set taken off Wendy. Need a bit of TLC but worked fine on Wendy. Needs some work on the connection flanges.

They are in S E London.

Open to offers.

Another shout out for a set assuming this score settled.

Mine have pin holes and not enough left to weld sadly.

Anymore for anymore ?

Hi Stewart
Pm'd you yesterday but no reply - will try again
Won't be making the sausage meet next Saturday but I am going to Crystal Palace Hillclimb next weekend (sun or mon) http://www.motorsportatthepalace.co.uk/ so might be a good opportunity for me to pick up manifolds on my way there or on the way home ???
The Hillclimb is a great day out btw

Afternoon Ron. Didn't check my emails yesterday bur will do shortly and reply.

There's major works being done to the two rounabouts next to the North mast which has temp lights that are only allowing one queue of traffic at a time so a big hold up. I would plan your route to avoid this.

Collection next weekend is fine on Sunday. Monday, I'm not around.

Quite often they rot along the trailing sections, which are straight pipe.

I found you can get straight pipe with flanges on quite easily on ebay, and it's usually a little thicker than original, then you can simply cut and shut the existing manifold, don't take it off at this stage just cut straight through and attach the flange to the rear section, with a new clamp, then tack weld it into place on the existing manifold, then take it off and weld all the way around.

I welded a repair section on a few years ago and it's still going strong.

Hi Adam,
I am struggling to picture your idea.
Any chance you could pencil a rudimentary diagram, photo it and post.
Would greatly appreciate it.
Thanks
Gavin

Apologies for the delay but it took ages to find the correct grade of engineering notepaper.


Anyhow this is how I did it, pretty much.

If you take the manifold off you can still put it on a couple of manifold bolts to line it up, measure up and do the initial welding.




It took so long to find that paper - most of the people I know either no longer smoke, or have passed on....

Prior to this I had welded around the flange to build it back up but this can be pretty unsatisfactory due to the unevenness you get around the joint, it doesn't really seal very well without loads of paste.

Thanks for that Adam, just seen it.....been away myself.

Excellent drawing skills and crystal clear.

Mine have pinholes appearing on the 'knuckles' exiting the block sadly.....and a repair looks unlikely as the material.is very thin.

Boo hoo

Hi just see your thread I have just removed a pair of steel manifolds from a 400se do they fit, a 350 drivers side one OK passengers metal thin and holed where it goes 2 to 1 they were for the next dump run can you make use of them ,based in Colchester

I have also welded up near the top, another common one is the 4 into 2 joints cracking open. You can chase the pipe down from the cylinder head ports where there is thick metal, and build metal up along a line, if you blow a hole through then work your way back from the established weld and join it up again. Do it on the lowest power setting.

If you're lucky the pinholes are on the outside and you don't even have to remove the manifold just weld in situ. Always remove the earth lead from the battery (assuming MIG or arc) to protect the alternator diodes.

Thank you for the offer Lee.
predictably.......its passenger side that is pin holed.
Drivers side seems okay
Again thanks
