Wearing in a new deisel engine

[Llamapup]

Hello All

I have done a search on this forum and not come up with much.

I'm getting a new 1.6 TD engine fitted in my Westy tomorrow. I'm pretty excited.

What are your top tips for breaking in a new engine? If the garage can't complete the work by the time I go home next Wednesday from the now famous holiday with the broken van, I may end up putting the first 300 miles on the engine in one long journey. It will be a mix of motorway and A road driving. There will be some stops and starts, some good size hills and some long stretches of 5th gear driving. Is this a bad idea? Is there anything I can do along the way to make sure the engine is getting the best chance to bed in?

What do you reckon?

Dont rev the nuts off it and never make it labour in too high a gear.

Read the whole thread..

It's about heat-generation in graded steps...

Normal (mineral/dino) oil for 1st 1500 or so, changing at 500

if it were a real NEW derv engine, as in brand new, not recon, and if it were someone elses, like a works van, truck ect, there is only one way to run it in, FLAT oUT!

however its yours, with your cash, so follow the advice given by the supplier, to stay within their warrentry.

Good basic advice from MM I think, which doesn't mean don't use the throttle pedal heavily, just do it in graded (time) stages... these things produce real internal HEAT, so they have to get used to it... watch for subtle inclines and headwinds when in top gear and/or heavily loaded.
