    Isuzu Injector service.

    I have a 120' with a 4BD1 in it. It has 220 000ks on it now and i was wondering if haveing the injectors out and checked is likely to be worthwhile at this 'young' age? Local diesel guy gave me a price of $50 each is all.

    How does injector cleaner compare to this as far as restoring the spray pattern and atomisation? Does it benifit the rest of the injector pump?

    I did have a search but couldn't find this info.

    Cheers

    A lot of people swear by Liquimoly Diesel purge, particularly on MB and VAG diesel forums. Its a solution that you run your engine on straight rather than added to the tank. I've ordered a can try out on my 300Tdi [I'm only taking my injectors out if new ones are going in].

    Only issue is, if I run the injector pump inlet and return lines into the purge solution, the lift pump will still run and flood diesel everywhere. As such I'll just fill up a new fuel filter with the purge and screw that on.

    Hi Dan, Unless the motor is running rough,or low on power I wouldnt even touch them. I did 750K in my old 4BD1 and had the injectors cleaned twice (both times they didnt need it). The main thing is to keep the filters changed regularly....Brian

    seconded...

    although they do like to have the crack pressure adjusted at about 500,000Km.
