Smoke coming out of the intakes.

I buy that it gets hotter than when traveling at 70mph, but the water pump and most parts are still continuously exposed to coolant temperatures (which will kind-of regulate engine temp/heat soak in traffic): the hotter engine bay/trapped heat will heat the block and because there is not much air flow when sitting still, the heat soak will conduct back into parts on the engine, most of it to eventually be dumped into the coolant, and shed off by the running fans. Sure the temps are higher but why in any would it be extremely bad?

At any rate, the fans running will help this situation I would think...

This engine, by design has the highest loads on the valve train at idle. Internally lubricated components that are only cooled and lubricated by the engine's oil need a constant flow of that oil to provide full film lubrication and to keep them at a sane temperature.

Low speeds have proven to kill these engines more than anything else in my research."
