My engine failed after 7K on the odometer... The piston came down the bottom. Whole engine 'flip up'. Upon checking the guys at the garage said there were irregularities in the fastening of the conrod bolts... Anyway they got me a new JDM Spec engine from the DC5 as replacement. hehehe. Just something to share with you guys. Mine is an '02.

Bench test and ran in are totally different though

Not ran in like that - no one wants to buy a car with running miles on it!!

But as Stu says all engines are topped up with some oil and "run-in" on the bench back in Japan before being shipped over

Honda it seems have never had a vtec system failure in probably all its cars....(if treated right etc). Engines have failed and thats the law of averages but still bloody low compared to other manufacturers.

But seeing as vtec was one of the first systems in mass, it is a testament that moving metal at 6k can change over and not break for 200k plus and keep in tune they are worthey of a pat on the back.

for complications compared with other cars(years ago) they were the dogs for being twice as reliable and producing so much power per litre.

Right at the end of the production line the cars have a small amount of petrol put in to them. They are started and driven onto a set of rollers like the ones you see when you have your MOT. The headlamps are checked/adjusted at this stage, then the car is revved (not to the red line) and the brakes tested.

The test track is approx 1.6km and used to be the runway for Supermarine Spitfire manufacturing. It consists of some variable textured tarmac a couple of s bends and a big roundabout at the bottom. The cars are warm prior to the test and are not usually cained on the first run, however on the return they are given a good work out through the gears and to the red line.

Someone mentioned the fume extraction on the production line, if i remember correctly they fit an exhaust filter to the pipe which filters particulates etc. if they are to be run for an extended (repair of FQA - Final Quality Analysis) period they have flexible extraction hoses to remove the fumes.

The units will be bench started/tested for approx 90 seconds (Takt) this cannot be construed as running in.

Jamziee, is your friend the engine plant of Assembly Frame manager?

I think it is worth considering that although the engine will free off and turnover more easily once run in, the process of running in is aimed at mating components and ensuring that the honing and grinding remains, this ensures that the oil can adhere to the metal ensuring a layer of oil separates the components. This ensures minimum friction/wear and maximised engine compression. It is not easy to damage the engine but if you run it hard constantly when new it may develop high spots where the metal components become smooth and can't retain the layer of oil essential to reduce friction and prevent seizure.

Speaking to my ex-colleagues at HUM there has been several instances of piston ring failure due to thrashing cold/new engines. You may get away with it you may not! Personally I don’t think it is worth the risk, treat it with respect when new and it will provide you with maximum performance consistently for a long time. It may also use less oil.

Good post.....saved me alot of typing!

As for extraction of fumes, near the end of the AF line, the cars are started for the first time unless there is something written on the VI card(Vehicle identification) stating not to start, there are suction ducts next to the track(line) these help remove the gases whilst ticking over before being driven off the line.The cars then drive across to an inspection pit where final checks underneath are done before passing onto a rolling road.The cars are passed quickly through the gears etc, they are then also checked for headlamp aim , brake test etc.
Basically they are not 'stone cold' when driven up the track.

Years ago i worked in the engine plant were the engines were made and tested 100%, as volumes increased in production, testing of all units was reduced dramatically with only sample testing.I believe our engine build quality was in the region of 99.9% right first time.

you just know that the kevs on 6 pound an hour love ragging your pride and joy round the track!

make it £14 an hour,i do things in other peoples cars i would not do in my own

[mozz792002]

if this is to be true it's nice to know that it's been ragged to sh-t before we buy em

Apparently not all engines are built/assembled and tested in Japan.

Nice to know we can put them together in the UK just as well as the guys on the other side of the world. 8)

Wonder where mine came from.

TegTypeR, nicely put in to context.

There were those who went with bigger engines, those who went with turbos and those who went with VTEC. Bigger engines got heavy and expensive, Turbos were renowned for their reliability issues (from days of old), and Honda were brave enough to stick with VTEC. So they then proudly made this annoucement regards their reliability prowess in this area.

Who said all the engines are built and assembled in Japan?

The Type R engines are though.

Yeah of course they are

I do love the "no VTEC failures in 15 million units"

Given how simple VTEC is....oil pushes little pin to link cam lobes together at certain rpm, it would be pretty difficultto make a system that DID fail...though I'm sure Alfa could manage it
