Message: [QUOTE="HobbyStock62, post: 1506597, member: 9597"] So this started this winter. Started off with my truck jelling up, it was like -10 for a week, and I was heading into work going 65, then just fell on its face and i was doing 30 until i could hit an exit, then in stalled out on me. Got it fired back up and drove it a mile or so back home and parked it. Then it warmed up, everything was fine for a couple weeks, then it started missing really bad to the point where it would stall. Cyl 7 and 8 contribution balance codes. So I put injectors in. The injector body in cyl 7 was kind of scratched up for some reason, couldnt see any issues, but thought it was strange. Runs great for two weeks, then it starts missing again. Cyl 7, so i pull the injector out, and the copper crush washer is blown off of it and o rings are burnt up. Put an injector in, again great for two weeks. Starts to miss again, this time 8. Same thing...So im really butthurt at this point and pull the cab, get all the injectors out and check the cups. The cups were pitted up at the bottom, but I couldnt see any cracks. I put a couple cups in 7 and 8 just in case. Get it all back together, runs great for about a month and now cyl 8 again...what in the actual **** guys. OEM injectors, torqued to spec, bolt holes blown out, and the cups cleaned out before injectors stuck back in each time. Am i looking at heads now? [/QUOTE]
