So I had greazzer rebuild my injectors on my om602 at 215k. I had some slight injector nailing and that cleared it up, I would recommend. In addition at the time of rebuild i installed new line between each injector. I noticed after the first time bleeding them it ran great. But after sitting for overnight or a day it has a very rough idle until it self bleeds again. I swapped in some clear bio diesel rated line to see if i could see it bleed down and in fact i can. So is this acceptable? Is it normal? Does this mean i need to rebuild my delivery vales? Any input would be helpful.
