Does anyone remember this thread?
It's been a number of years ago but someone posted a thred about a small timed pump that delivered oil to the turbo bearing at a constant rate for about 10 minutes after shutdown. Does anyone remember this thread?

Cool down timers are a replacement for your brain. If you just ran up a big grade with plenty of pedal push and high (1300 EGTs) give the engine some to time to distribute the heat loads before shutting her off. Idling a minute or so. Coolant capacity on these engine is pretty spectacular, you're not gonna hurt anything.

I never shut mine off before the egts were below 400, 300 when I had time. The truth is that if you're parking by the time you pull in a drive way, back in, get situated you're probably good to shut it off. Pulling anything heavy it never took more then 1 minute for it to cool down to a comfortable number. Only once I had to let it idle for 5-10 mins to cool down enough and that was because I was playing around at a back yard mud bog in some nasty mud with the engine at a redline for a long time.
Not to mention today's oils are a lot better than your grand dad's oils also. I've pulled a handful of turbos apart that spent 200+k miles living a hard life with minimal build up of anything in them.

These old school trucks cool down a lot quicker than the newer ones. I thought about a timer but never saw the need.
Even driving hard my truck was below 500F before I could park and below 400F in short order. I would let it idle until the family had collected their things and I was ready to jump out of the truck and only had to wait once or twice for a few extra seconds to get below 400F. It was usually below 350F.
My dad had a '16 RAM and his Cummins took a lot longer to get below 400F. His I would have gotten a timer for.
