I hope this video helps you out. My goal is that if you watch this, you won't need to spend thousands of dollars on mechanics who are going to do the work wrong and take you for a ride financially. Fix it yourself and you will love your truck even more!
A cracked injector cup is a nightmare for someone who is at the mercy of a mechanic shop, but it could be a great time in the garage if you don't mind getting your hands dirty. Just make sure you use the link above to learn how you can be sure you know that your injector cup is bad before spending the time and money on this project. Remember, no time spent learning is ever wasted.

For anyone watching....when I installed my injectors, I used a scrap piece of 2x4 to whack them in. Probably about 8 inches long. Hammered the 2x4 and you could hear and feel when it was seated. Worked great and didn't damage anything, just be gentle.

I've done plenty of these cups and many more engine designs volvo swedge style are probably craziest design I've seen. These are easy in my opinion

Thanks for the video. I work on Navistar’s MaxxForce series engines. Although they are an inline 6, they do share a few similarities with the 7.3. Not many, but a few. The injector cups look similar and I wanted to see how and where others install the LocTite. I have replaced a few and wound up having to take a couple of them apart again because the cup didn’t seal right. Not sure what happened. The MaxxForce doesn’t use glow plugs, they use an intake heater. One way I learned to clean out the cylinders I made a small hose for the end of my vacuum cleaner. I TDC each cylinder and then stick the vacuum hose in the hole where the injector tip goes. This pulls out the coolant and other debris that may have fallen inside. I wasn’t aware that the LocTite takes about 12 hours to cure before installing the injector(s). That’s good to know. Perhaps that’s why a couple of mine didn’t seal properly.

Great video. How would you know that it’s the injector cup crack causing the coolant to get into the oil?

RiffRaff diesel has been doing CNC billet stainless steel cups, installing mine today. Much better quality, and they reinforce the area thats cracks in the brass cups

I haven't done cups before, but when I did my injectors, I left the glow plugs and injectors out and jumped the started relay to shoot everything out. Then again after the injectors were installed and glowplugs out, turned it over again to shoot anything left out the glowplugs. He mentioned it around 13:55

The pennies stop brass shavings from entering the cylinders
