injector cup help
going to be changing the injector cups in the truck in the next couple weeks or so. never done it and I'm looking for tips and tricks to help, or whether it's something better left to experienced hands rather than trying it myself. I've heard there are some special tools needed and I'd really like to talk to someone who has done it before so I know exactly what I'm getting into.

Get in touch with rich, he goes by Tugley, Knows all and tells all about the 7.3, just pm him and he will get back to you, might even have a video to help that's the man I go to and I do this for a living.

Look up Tugly and go to his threads on the bottom, it tells you how. He drains the coolant from the engine heater first to remove it from the rails. Then pulls the injectors. You need to stuff some shop towels down the holes to catch the oil the best you can. Start with the back injectors first. then suck out as much of the remaining oil from each back injector before installing. Remove the glow plugs as well.

Oh my freaking gawd... we're all gunna die.
For some strange reason, I'm always drawn to cup questions - I guess I'm looking to pass on the "Injector Cup" trophy. The cup link in my signature is a link to my adventures with cups - but it doesn't exactly read like a how-to manual. It's more like a "there but for the grace of gawd go I" affair - but there is much to learn from the multimedia event, because the cups are holding.

ok, I appreciate it rich. my truck has the same white smoke yours did in the video. sometimes it's a no start too. but the fuel in my coolant has persuaded me that it's time to swap the cups. I'm assuming bad injector cups could lead to a truck not starting correct?
