This will probably get long, but I want to cover everything. I think I'm missing a crush washer and pushing combustion gasses into the high pressure oil system...
I had a bad high pressure o-ring and I was pushing oil into the fuel, so I swapped and resealed my injectors about 200 miles ago (I have 2 sets of injectors). It's an old truck and a work truck, so it develops oil leaks and fuel leaks here and there. I'm used to adding oil until I get around to fixing a leak. About a week ago, I drove it about 100 miles further than I'm used to. I didn't check the oil before I headed home and I ran low on the interstate and the truck shut down. I've had it happen before, but never on the interstate. I knew what I had to do and I knew it was going to suck. I added a couple gallons of oil and started cranking. I went all the way through the batteries, two jump packs, a jump start from the wife's car, and still nothing on the high pressure oil side. I let AAA tow it home and put it on the battery charger.
After a couple of days of cranking it intermittently, I finally got my neighbor to drag me (it's a 5 speed). I saw pressure on the high side almost immediately, but it still wasn't starting. After about 3 miles, it jumped to life at 2,000 rpm, but would die at any rpm below that (high pressure oil would drop below 500 psi). After a few more miles, it ran above 1,500. We drug it some more, and once it would run above 1,000 rpm, I let my neighbor go and just drove around on my own. After about 15 miles, I could get it to idle if I let it down easy. So I decided to drive it into town to get the rest of the air out of the system.
I drove it about 30-40 miles and it never did get completely right. I'd have to coast to the lights from a ways out because I never knew if it was going to die or not. If it died out, the starter wasn't going to get it going again. Pop the clutch, and it would start instantly (rpms above 1,000). If it was idling when I shut it down, it would start like there was no problem. Just to rule out the hp pump, I put it to the floor for a while and pressure never dropped below 2700.
I've had a crush washer drop off the end of an injector once before during a swap. That time, once the fuel o-ring wore out, fuel dumped down into the cylinder and it looked like I was fogging for mosquitos. This time, I do get some smoke while it's cold, but nothing like the mosquito fogger.
So, before I spend all day swapping injectors again, and find all the crush washers in place, is it possible that I'm missing a crush washer, I'm pushing combustion gasses past both o-rings and into the high pressure oil, and I'm just not getting a lot of leak down the other way? (I'd think the gasses would dissipate into the fuel rales.) Or do I now have a flaky hpop and I'm just getting the smoke from poorly firing injectors? Or maybe the IPR got some junk in it when the high pressure system ran out and now it's getting sticky? Any other ideas?
