I asked if i should replace the injectors while i'm in there and he said he wouldn't bother, he's got a 2 7.3's both with stock injectors and one with 269K miles. He did suggest i replace the glow plugs while i'm in there and get rid of the napa glow plug relay because it was getting really hot, to the point it was starting to smoke. The total for the relay and plugs was around $300. He said he ran the international relay and lasted about a year, and he's back to the ford mastercraft relay and it's been 2 years and still going strong. The other option he said he would recommend is the BG Injector flush, it's roughly $150, and they pour a solvant in the tank, and run the truck at high idle for 30 min or so to flush everything out. He said it works great and he gained almost 2mpg more on his trucks and better throttle response.
He also said DO NOT SELL that 7.3, the only reason he has a job is because of all the 6.0L's he's working on  So what do you guys think? I am laid off so money is tight, and i do have some time, but is this going to be a project that's over my head? He said there's a certain way you need to drain the HPOP and it's a rather complex job. |
I'm not sure how they can tell that it has leaking injector o-rings AND leaking IPR o-rings, as the tests can't differentiate leaky IPR o-rings from a bad HPOP very well. He's giving you good advice about not worrying about replacing the injectors, but his injector flush deal is way too high. You can do the same thing by draining the fuel filter and refilling with Seafoam (available at about any parts store) and running the engine. I've done injector o-rings, one side each on two different Saturdays in less than 11 hours total time, including running to the dealer for a replacement o-ring set, so I'd say they're high on that too.
He's also wrong on there being a difference between an International GPR and a Ford one in a Motorcraft box. They're IDENTICAL, down to the International number stamped on the bracket. His difference in service was just the luck of the draw.
If you're reasonably handy, you can change injector o-rings and glow plugs, as well as put new o-rings on the IPR (it's probably fine otherwise, so just get the o-ring kit from either International or Powerstrokeshop.com.) I found that the online Ford places had slightly better prices for injector o-rings and glow plugs than Int'l.
You'll need a deep 1-1/8" socket for the IPR, and a u-joint and a couple of short extensions for the back bolts on the valve covers. A short pry bar to get the injectors out helps. I use a brake adjuster tool. You should also have a way of sucking oil and fuel out of the cylinders to prevent hydrolocking after you reinstall the injectors. You should also roll the engine over with the glow plugs out to insure you get it the oil out.
tbpower's instructions and links are good info.
You can do it and save a ton of $ over what the dealer is wanting to charge you.
If you run into any snags, be sure and post questions here.
