Well I picked up a fuel pump today and put that in this afternoon. Boy am I glad I did. It may not take care of all my troubles, but it should eliminate fuel delivery as a problem, plus it was a good excuse to clean up the valley of filth. Installation was pretty easy, I spent alot more time cleaning up than swapping the pump. When I was cleaning under the HPOP, I found the nut and flanged bushing that secure the solonoid onto the IPR. Hard to say how much performance reinstalling them will restore, but having that solonoid loose can't be good. When looking at the old pump, I noticed that if I pull the tappet and reinstall it, it makes bubbles in the pump, so there is definately an open path there that fuel could get down, but maybe that's normal. I don't know if it's bad enough to cause the kind of oil dilution I've got though. I didn't try the new one, didn't want to pull the tappet and make it any easier to fall out. I found one spot where the exhaust manifold is wet with oil or fuel, I've read that can be an indicator of a bad cylinder. If I can get a set of o-rings tomorrow, I think I'll pull that injector and see if I can find a bad o-ring.

 

well hopefully that takes care of your fuel in the oil issue also. You did change the oil didn't you?

 

I replaced the o-rings on the injector that had a wet looking exhaust manifold, but the injector and cup looked fine to me. No visibly damaged o-rings or any sort of indication that it wasn't working. Got it all buttoned up, changed the oil and filter, and started bleeding the oil system. Topped of the hpop a few time, put in the fuses, and cranked it over. Started first crank. Then it got ugly fast. I FORGOT TO INSTALL THE HPOP PLUG! I initiated an Old Faithgul geyser of oil all over my freshly scrubbed motor. What a jackass. Luckily I had the hood up and was looking across the cowl when it lit off. Only ran a few seconds, but what a mess. Must have launched close to a quart, hard to say. I've got a big cleanup job tomorrow before another test run. Anyone know what size the hpop plug is? I haven't found it yet.

I think I got fooled by my dipstick too, I only got 4 gallons out of it, including what I sucked out of the hpop. That's what I put in it, but both heads and hpop were dry. So my fuel dilution wasn't near as bad as I thought, or my motor is hiding oil. I can't imagine the heads hold too much and one side was partially drained when I pulled the injector.

 

Can we get an update?

 

It turned out that both #1&3 cylinders were blowing a ton of smoke from unburned fuel. The wiring harness that plugs into the valve cover gasket had been worked on before I bought the truck. The #1/3 injector control wires were mixed up so those two cylinders were being fueled out of time. Once I switched the wires in the harness all is good. Running clean on all 8.
