Running in a diesel engine

[flightlessbird]

I vaguely remember reading some tips on running in a diesel engine on this website, any clues as to where I might find them?

Here is the article that you are looking for, under interesting articles...

Hope that helps!

Thank you

I hope that this will save some one having to change another Engine under warranty

The "Warming up a diesel" thread (sticky) is also worth reading if you want to look after your engine.

i already posted this elsewhere, but...

you guys, this forum has been a huge source of knowledge for me (i have a polo tdi), however i have a question that alludes to a little bit of driving from column A, as well as B.

my pogo was a demo, so we can presume that it was given a decent work out during the first 5000k's of its life (after which i picked it up).

but then, i picked it up and during warm up, i would never rev it higher than 2000rpm, and once it was warm i had the (deadly, i now understand) tendency to drop it into fourth at 60km's an hour and let the engine lug at 1300rpm, because i was stupid in thinking that aslong as im within the torque range, then its all good.

since 6700k's or so, however, i have been following the guidelines as per this forum.

so my question is- given the youth of my car, is the close-to 2000k's that ive been doing that to the engine, in all reality, going to have scarred it for life/ contributed to a lower km engine life? or as long as i follow the guide in the context of how to warm up etc, will my pogo's engine still be able to lead a full life?

im in my mid twenties and i have no idea about these things (expat kid turned foreign student living in japan= never owned a car before last year), so any experience, however positive or not-so-positive, will be well recieved.

thank you.

Hello BS (sorry, couldn't resist ),

Seeing as your polo was a demo for 5,000Km before you got it you can safely assume it was run-in with vigour, so your 1,700Km of babying would have very little affect on the life of the engine.

Just remember to give the engine some revs if you expect it to do some work (1,300rpm is OK if there is no real load on the engine, but you want 1,800 for accelerating or going up serious hills). Also use the right oil (VW 507.00 these days) and change it at the recommended intervals.

Drive on with full confidence

have no fear; oil will run out before your car bites the dust

thanks guys

.... for your input. if it werent for me stumbling across this forum, i would still be pussyfooting around in my pogo, unaware of the lack of good im doing the engine.

it should be getting some good hill work in the near future as it has finally started snowing!!!!! at buller.

thanks again, guys.

I found this post a good read - running in rules and description of factory run-in procedure:

Running in a diesel engine.

Plenty will disagree with me on this but i dont believe there is any real need to run in a diesel engine,
The most important thing is the first service as the swarf from machining when it was made ends up in the oil and filter.

The first service would actually be the second oil change the engine has ever had.

I did my time in an engine shop and we used run the engines hard on the dyno after a rebuild, You have to anticipate the stupidist customer possible!

After running you drain the oil and discard it, Then if its to be fitted back into a vehicle its common practise to refill the oil or send it out dry in a crate.

Manufacturers such as VW would put every engine on the redline on the dyno for hours before it leaves the engine shop it would be nearly glowing red hot! only then would it get the tick of approval and signed off, this would be the case with most manufacturers.

This is so the little old dear in -30 alaska or +50 kuwait can drive around in 1st gear at 6500Rpm for weeks in her brand new polo because she thought it was an automatic until her grandsons ears started to bleed !!

Iv just bought a new T5 4motion and i drove it as hard as possible on the journey up from melb to QLd. i think cars broken in slowly make a sticky lazy engine so im a firm believer in this. they may have been on a dyno during test but nothing gives them a workout like real roads and different air temps etc so never be afraid to spare that pedal!

I have to agree with you dude.

But i do believe that running in initially is a good idea. It's mainly a safety thing in my opinion, just to make sure that it's right. It's a comfort thing. However, running them hard initially is definitely the way to go.

Seems to be a fair varition in regards to wearing in the TDI motors.

When I collected my Caddy last week the dealer mentioned there was no need to have a run in period. Now, I'm never one to trust a dealer, but from some of the comments it appears there may have been some truth in it.

Have had a read of this guide (http://vwwatercooled.org.au/newforum...hlight=running) & am trying to put it to good use

One thing I'm unclear on, is how do you know the engine is warm (Caddy manuals have no temp gauage ). Even on a full cold start, revs do not change
