Diesel guys read this

[John With Beastly 302]

Okay this is quite simple. Diesel ignites from the high heat from the compression of air. Wet staking occurs when not all of the diesel is burned in the cylinders which causes fuel to start puddling on top of the piston (depending on combustion chamber design), and the the fuel will puddle up to a point were it washes the thin oil film off the cylinder walls. So as long as the heat is maintained via high idle etc..., I do not see a problem. Diesels like to be run hard because more load means more fuel and more fuel means more heat which translates into better combustion. Also it would be beneficial to note that after a long haul it would be a good idea to let the engine idle for at least a couple of minutes to let the turbo cool down. Why? Because we want to reduce the risk of oil coking on our oil return from the turbo, and do not even worry about ideling for ten minutes because we have got plenty of residual heat.
