 Exhaust Characteristics During Cold Start

As I get used to my new TC25D - I am getting to know what is normal. Would anyone care to describe what is normal during cold start, hot start, and winter start in the way of what the exhaust should look like, how long it takes to stabilize, when is it considered "warmed up"?

 Exhaust Characteristics During Cold Start

My Ford 1710 starts cold with a puff of gray smoke. During warm-up a fair bit of gray smoke occurs when adding throttle. Incidentally, I hold the engine under 1000 rpm for 30 seconds or so after the oil pressure comes up and then increase to 1500 rpm for a warm up. Diesels don't warm up much at slow idle, and they actually cool down from their operating temperatures. It's good to give a diesel a few minutes at slow idle to cool down after a hard run. Valves can be burnt etc. by shutting down a hot engine.

My engine doesn't smoke at any constant rpm during warm up. The puffing when adding throttle decreases to very little at operating temperatures and disappears almost entirely during a hard run. To me, the engine is warm when the gauge is near mid-range.

Diesels do like to work and it's good to give them jobs that they'll do at around full throttle periodically. My 1710 takes to puffing a bit more if I've been chugging around doing load work for a few weeks.
