Have a 59 560 Diesel that I have really never got to run smooth on all cylinders, Spent 700 dollars on the head and ported and polished and new valves, guides and springs and milled smooth with only 8 thousands taken off. Put in reman injectors and does not run well and sounds like one is missing and maybe a intake valve is hanging open. Can hear this small sucking hiccup sound at idle and seem to have two weeping injectors.Does the 282 head take the same injector as a 301 or are they exclusive to that 282? Any ideas or source for good injectors would be appreciated. Thanks Migraine
 
Well i think ya overlooked one small little detail here , now ya may have a sight valve problem but what about the pre cups ???? did ya pull them and look them over and if ya did have them out did ya get them back in correctly??? IF ya have a couple injectors leaking then ya need to pull them back out and clean up the seating area and put new sealing rings in and when installing them ya have to walk them in torquing them in a little at a time on each bolt untill ya reach the torque limit . There are two sealing rings per injector one for the pre cup and one for the injector. IF the injectors all break test with in 25-50 lbs of each one she should run fine if there is a big difference then ya had best go back thru them . Now if memory serve me correctly there was and early and late injector used on them and there were two different breaking pressure . Also how is the compression on this engine as this will have and effect . How is the injection pump has it been put on a stand and the CC's checked to each injector as this will also affect the engine.
 
Did you have the injectors tested? I'm pretty sure yours would have the early[ higher pressure] injectors. My 282 manuals are in the shop. I think I wrote down thw serial number break and body numbers. You really need to pull the cups and lap all the seal surfaces, they can be a pain to get sealed.
 
Thanks guys. I did have all the precups cleaned and all new seals and washers but maybe I did not get them in exact. Guess I will just pull everything apart and keep going till I find the problem. Thanks Migraine
