Alright lets see here.
This is my neighbors truck.
2001 F350 CCLB DRW XLT 7.3L/4R100 4.10 78K
He has some oil leaks fixed when he got it. I do know that one was a Cam sensor leaking.
It started smoking white on start up so he took it in to a diesel shop, Same shop has done work for me and did great work.
They Replaced the #8 Injector. ( No smoke for a couple days)
It started smoking again. went back to same shop.
Before it went back we took a snap-on scan tool and did buzz testing on the sticks. ( Passed they all sounded good) then Cylinder Contribution Test. It says #8 out of threshold ( however it words it) Would it think because it was a new injector that its bad or could 1-7 be bad and it show that one cause it is different/newer?
Shop tests and finds no issue so they try a new Glow Plug in #8. still smokes so they put another new injector in it. ( they say no smoke)
He gets it home and a couple days later smoke it back.
Now ( maybe past week)
When the truck is cold hasn't ran for a day or so it starts and runs find for like 15-30 sec and shakes for 10-20 secs then runs perfect. ( still smokes a on start up.)
Now the list of what people say could be wrong with it.
injector O-ring ( I believe this could be the case due to the truck sitting alot before)
Injectors ( one or all)
Glow plugs ( one or all
ECM on its way out
Fuel blow cracked
Now and I missing anything. and what can I check/ test to prove anything. After the truck runs for about 1-3 mins it is totally fine. runs fine, doesn't fall on its face if you hammer it NOTHING> So can someone educate the Cummins guy who doesn't was it admit defeat.
