Drive slower before you get home and let it idle while you take off seat belt etc. Don't want oil to cook in the turbo oil gallery as heat runs up the turbo shaft after shutdown. No need to be anal but don't pull off the expressway and shut the endine down immediately. Common sense.:D

I was told by a diesel mechanic that all this turbo cooling stuff pre-dates intercoolers and modern bearing turbos, and a bit of gentle driving before shutdown is more than enough...
You are probably right Stuart.Quote:

Having said this (as mentioned in previous post) I'll keep doing what I'm doing, knowing that I am looking after my hard earned $ as best as possible.

Thanks again fellas.
I know its common sense to drive slowly and let it cool down gently. I would never turn it right off after heavy use.
Im upgrading from a diesel Challenger so thats what i always do..
Just wasn't sure about the twin turbo setup the new disco has whether it would be any different..
Good to know about the "no idling" at startup.
The more important thing with diesels is to give them a hard time.
The problem is how to do this with something that makes that many Nm's:p
Why give them a hard time??? Please explain
From wiki--
"Running the engine under very light or no load prevents the oil film placed on the cylinder wall from being scraped away by the expanding compression rings. The rings will instead �hydroplane� or ride over the deposited oil film, allowing it to be exposed to the cylinder combustion. The oil film will then partially burn on the cylinder leaving a residue that will build up and oxidize over time. Eventually this leaves a hard deposit on the cylinder wall that is very similar to the glaze left from flash burning. My caution to those just running the engine as a normal daily driver (without some loading) and especially those who love to idle their vehicles, expect some VERY extended break-in periods Expect oil consumption forever due to oil glazing. The rings never really seat well if they cannot expand from the dynamics and heat that a load produces."
so hook a boat up and tow it up a big hill;)
but hey,, dont believe me,, ask the question in the Tech Forum :)
I think it's well known that diesels need to be worked on a regular basis. During run in, even harder.
Extended idling is not good (a couple of minutes does not hurt).
It's just common sense for cool down as others have said.
Brett....
so is foot the the floor a good way to run them in??
No...
I'm sure the LR handbook explains what is required--;)
