I was kinda thinking earlier that it might be air in the fuel or oil passages and it might take a while to work it all out. That's one of the disadvantages of the dead end fuel system. It can be a real PITA to get the air worked out.
T what made you change your injector sleeves? Just wondering, mine is still using oil like a dog eatin' boiled okra, it just goes down so fast and easy. No smoke just black soot on the bumper. Don't miss a beat, runs like a scalded dog, and gets 18.5 mpg, still. I'm thinking injectors, got 225K on truck. I know I have put 105K on it myself. Engine completely rebuilt, new rings, pistons, valves, head job and 2 turbo's. Don't leak a drop AT ALL! STUMPED?
I was getting fuel in my coolant tank. With help from this site found cracked sleeves .When i pulled inj. also found bad orings .Runs great what a job to do with heads in the truck.
