Hi all,
Been getting diesel in water and water in diesel tank, so assumed to be injector sleeve seals. Anybody in Devon got a puller I could hire Please? When I do get them out is there any reason why I cannot use Viton o-rings of the correct size, or have Isuzu made their seals out of unicorn fart and hen's teeth?
Any comment of help would be very welcome

Managed to get the sleeves out with a puller I knocked up with an anchor bolt and some scrap, without any damage to anything. What tips are there for re-installing the sleeves, what should Iube the new seals with etc. How does the sleeve seal in the head where it goes through to the combustion chamber?

they need to be tapped back in to place and remember to line up the holes in the head with the holes in the sleeve, it's an interference fit and i use a smear of rubber grease but you can use a smear of oil or diesel or antifreeze

Would silicone grease on everything be ok as I know its O-ring friendly, would it be ok on the interference fit parts also?
