Hi
A little background, I bought an 04 F350 4x4 with a 6 speed manual. I got the truck for cheap because someone forgot to set the ebrake and the truck rolled into their pond. The truck was pulled out in about 20 mins then sent to the shop to have all fluids changed. After the mechanic changed the fluids and started it the truck was puking white smoke. The mechanic called the people I bought it from and at that point is when they chose to sell it. It was the oldest truck in their fleet.
So when i bough it, it was blowing white smoke. I bought it knowing I was going to pull the heads and replace a lot of stuff anyways so it was a none issue for me. When I got back to my shop I went ahead and connected my Autel Maxicom MK808 to check the codes and see anything else there might be worth seeing. There were a couple codes for glow plugs and a code for cylinder 7 contribution.
Jump ahead to current, I have replaced the heads with remanufactured heads from American Cylinder Head in Oakland, CA (both were cracked). Installed new head gaskets, ARP studs, new OEM injectors, new glow plugs, new dummy and stand pipes, new oil cooler, upgraded EGR cooler, upgraded up pipes, 4" down pipe and exaust, blue spring mod, upgraded water pump, SCT BDX Tuner, Powermaxx turbo, and South Bend Dual friction clutch.
It's all back together and still blows white smoke and I am still getting the same cylinder 7 contribution test failure. The motor has 210,000 miles. The cylinders all looked good though I didn't do a compression test (which I should have). During tear down and cleaning I did not run across any needle bearings like that could be found in lifter.
Also I should note, the truck seems to have a replacement motor. The block has 18mm holes and has the early aluminum body HPOP. The heads on the other hand have 20mm holes and the IPC is located on the passenger valve cover and not connected to the HPOP housing like normally seen with the early model 6.0. Also should be notes the ICP used is from the later models with the brown connector and not the black connecter like from the earlier models.
So question is, any suggestions on what could be causing the #7 contribution failure?
