New guy, new question
I love the site. I am a new owner of a '06 F250 turbo diesel. I have heard of a mod that allows you to cycle oil through the engine prior (and after) running. Can someone point me to this? I have no clue what it's called and I'm not ashamed to say I am learning as I go. Thanks for the great site!

Turbo Cool Down Timer
You are probably talking about the Turbo Cool Down Timer. This allows the engine to run for a preset period of time after you turn the key off. This circulates oil through the oil cooler wit the engine running and then through the injectors and the turbo to prevent turbo bearing "coking" and injector "stiction". These 2 anomalies happen most often when you use non-synthetic oil. The oil will actually cook and leave an oil residue that sticks to the bearing and injector surfaces, therefore, decreasing bearing and injector tolerances and that leads to turbo and or injector failure. Synthetic oil eliminates "coking" and "stiction".
I don't know if there are kits available to circulate the engine oil after the motor shuts down. I can envision such a kit but it would require a separate electric oil pump, HX, cooling fan and control module. Plus I believe it would pretty expensive.
From one vet to another, thanks for your sacrifice and service.

It seems to me that back when I got my truck (2007 or so) there were a handful of pre and post lube systems running around. They used an electric pump to build oil pressure before the engine was started, and after it was shut off for a minute or two.
The idea was to get oil into all the bearings, etc before the engine started, reducing wear. And to continue to oil the turbo until it had completely stopped turning after engine shut off.
It doesn't seem like these exist much anymore. I found very little on Google.

Woundedvet, if no one has said it yet, welcome to FTE and thank you for your service to this great country.
It is a valuable addition to any engine...and it isn't new technology. I know of stationary diesel engines back in the late 80s that had a pre-lube pump to keep the engine warm since the engines were stand-by GenSets that had to be up to full power 2 minutes after the power went out. Hearing a 3508 come from dead quite to full load in under a minute is pretty wild. In a former career the company I worked for had a couple of D4 bulldozers with a pre-lube pump (engine is about the same size as our 6.0L) that would sound like the starter wasn't engaging when you'd turn the key to START. After the pump created a preset amount of oil pressure the engine would start. With that in mind I went looking under the term PreLube and this is what I could find....

)
This one might actually work for the 6.0L with a little custom plumbing/wiring.
