this wasnt the reason i overhauled the injectors. fuel economy was getting a little bad, heaps of black smoke, 20 years old and about 250000kms with all kinds of unknown fuel thru them, from here in aus and also png. thats why they were done not for any type of knocking noise. this just mayby seems to be a byproduct of getting them done which im a bit sus on.Hi Fellas. It never fails to amaze me the number of people who rush off to unload their hard earned cash on injector work every time the good old diesel gives a cough or splutter. These specialists will tell you anything to get their hands on your filthy money. Well serviced diesel engines will do huge mileages on a set of injectors. It pays to try almost anything before you go up that road. Cheers.
i know what ur saying but its not consistant enough i would have thought. but i guess possible. i dont really feel like pulling the head off to check though.may be loose pre comp chamber/ers. when i got the head off mine 2 of these fell out. it had a slite knock befor this which sounded sort of like blocked injector/ advanced timing sort of thing hard to explain on a computer. duno just my 2 bucks
