new injectors, blown copper ring, now no boost
2005 Ford F350 6.0. New STC fitting 2 months ago, EGR Delete kit, new oil cooler as well. Yesterday I put in 3 new injectors and got the truck running. An hour later i blow one of the copper rings and lower seal on my number 6 injector.
Alot of fuel drained into cylinder, nearly causing a hydro lock. I get towed back to town, and with a 5 speed i let the engine turn over on the way back to town to get fuel out of the cylinder. I tear apart and fix again, and Although it blew a lot of grey smoke from all the diesel fuel that was in my exhaust, it ran like a raped ape. I drove it about 15 miles and had good boost pressure. This morning I started up the truck and there was no boost. I drove it back to the shop took off all the plumbing for the turbo and inspected it. All was good. I also unhooked my batteries for 60 minutes and let it reset its computer. I put it back together started up and had good boost pressure all the way to Indianola (20 miles). I let it idle for 10 minutes and then drove back and no boost pressure. All the plumbing for the intake is still sealed and I am lost at this point. I have 50 psi fuel pressure while underload on road. No black smoke. No power. New Fuel Filter. Tried reseting my computer and that didn't do anything either. Any suggestions?
I wonder if all of the raw diesel fuel that went into the exhaust from the blown seal and hydro lock may have sooted the vgt up? Also, could the fuel system have been damaged due to the pressure from the #6 cylinder going back into the fuel system?
