Defender_300Tdi Posted November 21, 2010 Share Posted November 21, 2010 Hi All I am after a bit of advice on running my newly remanufactured engine in......it has been done top to bottom by a well know engine remanufacturer and fitted with a reconditioned fuel pump, new injectors, new turbo etc etc . Only thing is I have heard conflicting advice on the best method for running it in: - Load the truck up and take it for a 500 - 1000 mile drive so that the engine has to work a bit rather than doing the same trip with just empty truck..so that the rings bed in. - Run it around town and clock up the miles that way. - OR put a tractor on my trailer and tow it for a 750 miles or so.... Which method (if any) would you advice to give me the best long term engine reliability? Sorry if I appear a bit green on this...this is the first new engine I have EVER had!

western Posted November 21, 2010 Share Posted November 21, 2010 didn't do anything special when my 200Tdi was fitted new back in mid '93, just drove it as normal, without letting it labour & no harsh acceleration, must have done something right as is got lots of miles to it's credit.

Rob i would of thought that putting it under load so early would cause damage not help it bed in but i dont know i would prob do 500 empty truck 500 full but not sure just my view Quote Link to comment Share on other sites More sharing options...
Defender_300Tdi Posted November 21, 2010 Author Share Posted November 21, 2010 So would towing a trailer around for like 500miles befit me in the long run? I am just a bit worried about polishing my bores!! Rob Quote Link to comment Share on other sites More sharing options...

90MAD Posted November 21, 2010 Share Posted November 21, 2010 that way you can bed it in nice and smooth and then put it under a light load maybe a few light (long not to steep) hills to get the turbo bedded in to, but only when engine nice and warm Quote Link to comment Share on other sites More sharing options...

reb78 Posted November 21, 2010 Share Posted November 21, 2010 What did the engine reconditioner reccomend regarding running in? Someone reputable like Turners would know the answer to this question and i'd be inclined to go with what they say. Quote Link to comment Share on other sites More sharing options...
Marco Posted November 22, 2010 Share Posted November 22, 2010 Just use it normally, no overloading and no driving like a vicar (Richard Turners advice...) It will take 500-2000 Miles IMO to run in. Cheers Marco Quote Link to comment Share on other sites More sharing options...
Richy B Posted November 22, 2010 Share Posted November 22, 2010 You can buy a "running in oil" we used to remachine british sports car engines ( jags healeys mg"s ect) Anyhow we had a particular garage who used very high spec oils from the word go, And suffered from smokey,poor performing engines, we converted him to running in oil for the first 500 miles and no problem since, Worth a thought Quote Link to comment Share on other sites More sharing options...
Mocha Bear Posted November 22, 2010 Share Posted November 22, 2010 I am just a bit worried about polishing my bores!! Rob Just don't let it idle for long periods of time, also try not to hold one speed for long (engine speed). Ramp the load on and off, so going up and down hills is a good idea. I would start with low loads (empty truck) but after a couple of hundred miles start to up the load. once the oil consumption of the engine has reduced (will use a bit to start with while bedding rings etc.) it is a good time to start putting full load on, i.e. full pedal accelerations and climbing hills with weight. Basically as people have said above, just be 'kind' to it to start with but don't be afraid to load the engine, light loads will cause the most polishing!

Maverik Posted November 22, 2010 Share Posted November 22, 2010 Read this article My link In this case the context is a small marine type engine, but the information carries over to Automobile engines too. If you can understand what the full problem is then you can apply the correct solution. Quote Link to comment Share on other sites More sharing options...
cackshifter Posted November 22, 2010 Share Posted November 22, 2010 Assuming the bores are properly plateau honed and new rings are fitted, I'd go for it and use it fairly hard unless it feels very tight. See link. And use a running in oil or something similar, rather than a full synthetic, and change it after max 500 miles. Nigel Quote Link to comment Share on other sites More sharing options...

Nigel A very interesting link you posted Nigel, and it does tie in with a few other sites I found with regard to newer engines, but I'm guessing it depends on the grade to which the refurbished engine bores where honed to.
