ok my truck just recently after pulling a car on a trailer started burning oil bretty bad. it went through 6 qts in a week. my buddy who used to work at international said it may be my injector o-rings or the internals of the injectors thats causeing it to burn it. but i just put in used injectors before winter so i would think the o-rings would be good since i replaced them with new ones. also i have the 10k resistor mod on my truck and when i take tghe resistor out now the truck lopes real bad and has no power. so it pretty much wont run without the resistor in now. i have it set up for my old set of injectors to get rebuilt by jim at the end of the month but i just want to be sure (or as sure as i can be) that it is the injectors. this truck doesnt leak so its not leaking any out.
