'02 7.3 diesel injector o-rings.
Please help me! I have a 2002 7.3 liter powerstroke with 95,000 miles. Straight pipe exhaust, K&N cold air intake, all else stock. Pull camper and boat in the summer. Doesn't run much in winter. 3,000 miles a year. For the last 4 years about every 3,000 miles I blow out the injector o-rings and blow all my oil into my fuel tank. When this happens I put more money in oil than fuel into this POS! I have had Ford do this, and mechanic friends. No differance in results. In the last 4 years I've done: Turbo, IDM twice, engine wiring hareness, valve cover gaskets, valve cover wirring harrnesses, glow plugs, glow plug relay, injectors 3 times, injector o-rings an additional 3 times, o-rings on HP oil pump, o-rings on fuel pump. I'm wanting to know why these injector o-rings keep blowing out. I just had it done again and it runs awesome! But I know it won't last but maybe 8 months and we'll be doing it again. Any help will be much appriecated.
I've been asked to sell it, but I couldn't ever sell this to anyone I know in a 50 mile radius. It's that bad, but the truck looks great!
