1998 E300 in the shop for a few different things. Turns out there is a crack in the exhaust manifold. Any thoughts as to how/where I might be able to obtain a good condition used one? My indie is looking around....but I told him I would try as well.

Thanks.

Have a muffler shop or stand-alone welder weld the crack together.

You'll probably have to remove the manifold.

Don't forget to grease the screw and threads on the spring compressor.

Hopefully possible...but apparently chance that it won't be...

I was told many years ago that welding casting iron was possible. What needs to happen is the area around the crack needs to get red hot with a torch then weld the crack with an arc or mig or tig welder. Another trick would be to cut a v in the area where the crack is to get decent penetration.
That's what's I was told by a ship fitter in the navy.

I have done a lot of welding in the past but I am no expert. I have always been told to file a groove in the crack and fill the crack using brass brazing rod after heating the cast iron. The melting point of brass is approximately 1650 degrees Farenheit.
