Is 'running-in' necessary?????

[big daddy]

G'day guys,

I'm on a 4-month 'grey nomad' caravanning trip up through the centre to Darwin, across to the West then down to Perth and home to Newcastle.

Unfortunately, I blew a motor 50 miles out of Alice Springs and now I'm waiting for an exchange reco engine from Adelaide.

(This was only 5000ks after I shelled out $1500 to have a coolant leak repaired before we left home.)

I've heard different stories and I'm in a dilemma.................................

Some so-called 'experts' say that I should 'run-in' the motor over some 1500ks before hitching the van on and continuing on my trip.

Others say that its ok to just take off and really work the engine - it'll be 'good' for it.

I've been here in Alice for over a week now and should have a replacement motor fitted at the end of next week.

So, what's the general school of thought??????

Can I have arguments/comments supporting either way please.................

I'd really appreciate constructive replies I'll have plenty of time to mull them over.

My vehicle is a 2003 3lt turbo diesel automatic Patrol.

Many thanks,

Big Daddy
