This outfit in Canada has a new old stock one listed, however the part number he has listed does not correspond with the EPC.  Hmmm.  Maybe email him and have him double check the number cast into the part itself:

Mercedes Classic Center will sell you NGK BP6ES - they use those plugs in many of the classic models.

I see the big "crack" ... i.e. the missing piece of aluminium.

Does it go all the way to the flange, i.e. the rubber hose with the clamp will not seal properly?

Ah yes I see it now.  That's a tough one.  You can try and epoxy weld (like JB Weld) a piece cut to size to fit into the gap.  Risk is if that piece let's go then it'll end up in the water passages somewhere which would suck.

Other option is maybe a thin sleeve over top?  Failing that you'll have to replace the whole manifold which is a huge and costly job.

I was thinking of installing a thin Copper sleeve which could then be attached firmly with JB Weld or similar . Intake manifold is NLA from Benz and I don't have a spare. Have asked after a whole engine as a rather excessive spares kit. PN is A1001404401

It looks like the manifold simply unbolts and can be resealed. I already have the fuel distributor and injectors out... installing a sleeve is not a long term safe solution as it really depends on a very clean joint and heat cycling will eventually cause it to fail.

That's what I thought (I read) and thanks,

The connection between the manifold and thermostat housing is a short rubber hose secured with 2x hose clamps.  Not sure what you mean by missing aluminium?

After some time spent overseas and a short period of enjoyment, I decided to continue with the work on the car, starting at the cooling and fuel system at the engine. 

This evening I found a piece of Aluminium missing from the intake manifold to thermostat housing coolant fitting. Unsure what to do. This job has instantly become a lot more complex.

Here are the links I installed on my car: Rear Sway Links. You should be able to see whether the part is broken on not by looking behind the rear wheels with a flashlight. The sound comes from the broken end banging up against the dust guard for the brakes.
