Message: [QUOTE="Black 02, post: 1364211, member: 6916"] I just the injectors back after having them gone through. Just got them installed Saturday. After the air was out of the system, the truck runs as smooth as it ever has with your trial tune. Cruising, idling, starting cold… Everything is top notch. Just a slight haze of exhaust. On a side note, I have a concern that I may have a blown HG. I sure hope not, but I’ve heard it’s somewhat rare on a 7.3L. I’ll try changing the degas bottle cap first, but it’s not real old. Anyway, after getting 100 miles or so on the truck and it was fully warmed up for quite a while, I got on it to see how it ran. The tune is just a trial tune from Swamps, so it’s not putting max fuel into the cylinder either. Anyway, after getting on it and building about just a little over 45 pounds of boost, it puked less than a coffee cup of antifreeze out of the tiny hole under the degas cap. I drove about 5 more miles and parked at my house. That’s when I noticed the antifreeze. It actually started to do this a few weeks ago before I pulled the injectors. Just a small amount of antifreeze on the outside of the degas bottle near the cap. When changing the injectors, I found a leaky injector cup and replaced them all. Cleaning the cups holes extremely well. Figured that was the problem of why it was doing it. I changed all 8 injector cups and used the proper install tool with the correct Loctite. I can’t fathom it still being an injector cup because I cleaned them extremely well. The truck has just a slight greyish haze of exhaust and the oil doesn’t seem to have any water in it. It fires up cold really great, idles super smooth, and cruises on the freeway awesome now. I'm really happy except for this damn antifreeze leak. Engine has cometic head gaskets with ARP studs. I sure hope it's just the degas cap. If I didn't have bad luck, I wouldn't have any at all. [/QUOTE]
