Re: Turbo Cool Down
[ QUOTE ]
The Owner's manuals say three to five minutes, and I wait at least that long...

The owners manual does discuss cool down time, but only in relation to extending turbo charger life. It mentions nothing about cooling of valves, pistons, internal bearings, etc. Fact of the matter is, there is no way that those internal parts are going to cool appreciably in 3-5 minutes. However, exhaust gases do cool in a short time as the piping containing them is thin and exposed to much cooler atmospheric temperatures so that thermal cooling can take place.
If you look in a gasoline engine owners manual, there is no cool down period mentioned (at least I have never seen this mentioned in the plethora of gasoline trucks I have owned.)
