Shop Talk: Tech Tips from a Lifetime Under the Hood…

A Ford 6.4L 2008 truck arrived at M&D to have a diagnostics test run for the following:

  • Check engine light
  • De-rate wrench warming light
  • Extremely low engine power
  • Plugged diesel particulate filter (DPF)
  • Plugged diesel oxidation catalyst (DOC)

History provided by other repair facility:

  • Overhauled the engine in house due to engine overheating
  • Replaced the turbos due to oil leaking out of the exhaust after the first drive
  • DOC and DPF removed and cleaned twice
  • Check engine light was always on
  • De-rate warning wrench light was always on
  • Plugged exhaust
  • Reduced engine power

The repair facility that M&D received the truck from had overhauled the engine but could not release it to the customer due to the problems that the truck was experiencing.
