Hi, I am new to this site and need some help. I recently had all new injectors, cups, wiring harness and glow plugs installed in my 7.3. I have 230,000 on the truck and figured it was time. When I picked my truck up from the shop and drove it home,it had a pretty bad injector knock. So I called the shop and they told me that they just needed to break in, and it will go away. So I drove it for a week and it just got worse. They ended up towing it back to their shop because I lost all power and white smoke was pouring out the tailpipe. They called me up a few days later and said that one injector was too tight so they replaced it. I have been driving it for three days now, and I'm getting blue smoke on acceleration. And the knock is back. Please help!
