  • Oil pan/rear main seal.

Drivability issues:

  • Misfire
  • Loss of power can be caused by damage to the turbocharger
  • Sticking injectors
  • Under valve cover harness
  • Injector driver module/IDM
  • Fuel and oil quality 

Cooling system concerns

Hard to start when cold

  • Sticking fuel injectors, bad glow plugs, and glow plug relays are common issues if your 7.3 has issues starting cold.
  • If a vehicle has low compression/blowby/uneven cranking this will also affect the ability to start when cold.
