    Default How difficult/expensive is it to work on a Opel 1.7D Diesel engine?

    A relative has one of the Opel bakkies with the 1.7D Diesel engine, which if I recall correctly uses an Isuzu sourced engine. Apparently it was filled with dirty diesel, lost all power and was making lots of smoke. The mechanic who looked at it at the time said the pump and injectors are klaar. Knowing mechanics and how pumps and injectors seem to get blamed for anything and everything that goes wrong on a diesel engine I thought maybe I should have a little look at it. Maybe they get lucky and it's not overly expensive to repair, it would be a great help for them to get the vehicle running.

    But before I do that I thought it wise to ask how easy are those engines are to work on and what is the cost and availability of spares like?

    Especially the prices on the diesel pump and injectors.

    Eish, a mechanic mate of mine bought and fixed one of those a few years ago, he said he just had crap finding spares at a decent price. He basically broke even on the deal.

    But it is probably worth stripping and checking.

    Had one a few years ago... I was cheaper to fit a import engin than to find the spares.
    Got a engin at engins and more.

    I also have a recollection of the spares being very expensive on the 1.7D. I suppose it's the typical diesel engine story, when there is very dirty fuel involved the costs can be astronomical.

    But wouldn't an older pretty basic diesel like the Opel have a more robust pump, maybe just the injectors are fubar?
    The mechanic who looked at it probably heard it was bad fuel and immediately said pump and injectors without properly testing anything.

    Was it a 1.7D engine complete with diesel pump and injectors?

    Diesel mecchie friend of mine bought his daughter one at a giveaway price..... engine had to be redone. He thought it was the best thing that could have happened with him. The engine was not too bad most parts was readily available and not too expensive. Then it came to the pump and injectors, had them overhauled by specialists and fitted it one Saturday afternoon. Took him two weeks of nightmares to get this "thing" timed so that it made some power and had lower fuel consumption. He vowed never to look at it again, he would rather pay to have it fixed.

    It is old school standard aspirated vintage pump technology, be aware

    Thanks, that seals it I'm not going to touch it. If a diesel mechanic struggles no ways I'll even come close to fixing it. Probably best if they sold it as is.

    There were some 1.7 turbo versions from the UK that made it move along nicely. The engines looked terrible with all the rust caused by the salt on the roads but were better than what they looked. Might be scarce by now? Very light on fuel.

    Biggest problem I had was big hands - small engine!

    If I remember correctly most of the bolts are stretch bolts which also add to repair costs.
    Evidently the fuel pump is inclined to collect sediment in the bottom of the pump. To clean it out it would have to be stripped by a specialist. Fuel filtration once again very important.

    Yes complete engin. Diesel pump and injectors were ######.also the turbo was very expensive to rebuild.rings an pistons had to be imported. The complete rebuild worked out to about +-35k plus. A replacement was 12k
