Does anyone remember a system that fills with engine oil at start-up and holds about a quart untill the engine shuts down and feeds the oil to the turbo for thirty seconds ( I guess ) to help keep the beartings alive. My memory being what it is, I could have sworn I read about something like this a few years ago but cannot remember where.

 

I've heard of pre-oilers, but don't know that I've heard of post-oilers...

but you run Amsoil... if we're talking about a non-abused factory turbo that doesn't see over 35psi and is cooled down before shut off, there's no reason it won't last as long as the rest of the engine.

Moroso Oil Accumulators

The Moroso Accumulator is an engine saving add-on to any high performance oiling system. It is designed to provide oil pressure should the normal engine oil pressure drop below the optimum operating level during hard acceleration, severe cornering or hard braking or when oil surges away from the oil pump pickup. #710-23930 is a vertical, gravity fed unit designed for small-displacement light-duty applications. #710-23900 is a pressurized version intended for competition use and features an air pressure gauge, cold start valve and free-floating piston which allows for versatile mounting. Mounting bracket kit available separately.

This what your thinking of? http://dodgeram.org/ki4cy/preluber/Preluber.htm

 

There's no need to worry about the stock turbo on these trucks.

Others will flame me, but honestly, you don't need ANY kind of cool down time 90% of the time. The oil coking concerns were more of an issue with older tech oils and older tech. I'd let it idle a little if I had been towing heavy for a longer haul, but most of the time you really don't need it. I mean, how often have you heard of a turbo failure on a stock truck? I guarantee that there are a substantial numbers of CTD owners who NEVER let their truck cool the turbo.

The other thing that others will flame me on is this: I'd say with a high-quality synthetic oil, you almost never need to idle for the turbo's sake. You could probably damage the turbo still if you shut the engine off at 33psi of boost and 1400°, but any sane driving practices will keep the turbo alive without much extra effort.

I won't flame you, I'll agree.
Many folks are much too **** about turbo cool down especially after installing a pyro. I don't want to even think about what would add up to several wasted weeks of my life idling waiting for the temp to hit 300°, I just turn it off after I stop. After over 400K combined miles on my trucks if this is problem it's sure taking it's time.
Won't even tell you how I feel about the turbo cool-down timers.

 

I never even thought about it until I put my pyro in. Now I'm **** about it. Funny how that is. I even got my wife to do it when she drives the truck. I guess I can slack off a bit on that.

What about "performance" turbos? Do they need cooled down?
