1971 Mercedes 280S with OM617 idling in cold weather

This is my 1971 Mercedes 280S (W108) with a Mercedes diesel OM617.910 ("300D") and 5-speed manual transmission. Idling right after startup, temperature outside is -3°C/26°F. After about 15 seconds of glowing and 5 seconds cranking, the car started on 4 cylinders and the last one joined the choir a few seconds later. Idles good with idle adjusted to highest possible. Audio sucks and does not do justice to the real thing, the screaming belt sounds much less in reality.

Google for "fat franz" and you'll find my blog that has tons of pictures of both cars, including engine mount setup. Have used two approaches, since it's a hack job neither one is more correct than the other, do as you like and good luck :)

Hi,

you emailed me ages ago about my OM617 into 108 project. Finally found an engine to replace the one that died 3 days after the conversion. Can I see what sort of set-up you've got for the engine mounts and any other vibration absorption? Would love to hear all the other details of your putting-diesels-where-they-don­'t-belong projects so far.
