Beneath, you will see that extra about what years are Ford diesel engines to keep away from and why.

Ford Diesel Engines To Keep away from

The Ford Powerstroke diesel engines are extremely popular.

However attributable to some design errors, some years of diesel engines needs to be prevented. That’s as a result of they’re susceptible to frequent failure and require fixed repairs.

Let’s get a fundamental thought in regards to the fashions and what years to keep away from.

12 months Engine Capability Issues Which yr to purchase
2003-2007 Powerstroke 6.0L Head gasket failures, FICM failures, oil cooler, EGR cooler, EGR valve, and VGT points N/A
2008  Powerstroke 6.4L DPF points, a leaking radiator, cracked pistons, oil cooler points, poor gas economic system, EGR cooler situation 2010
2011-2014 Powerstroke 6.7L Radiator Leaks, EGR Cooler Clogged, EGT Sensor Malfunction, Turbocharger Issues, Injection Pump Issues. 2015 and onwards
1994, 2001-2004 Powerstroke 7.3L Failure Of The CPS, Turbocharger Up-Pipe Leaks, Noise, Gas Filter Housing Leaks, EBPV Failure. 1998-2000

Now, let’s see what the issues are.

Which Ford Powerstroke 6.0L Years to Keep away from?

2003- 2007 fashions of the Ford Powerstroke 6.0L are unanimously notorious amongst Ford truck customers.

  • Oil Cooler Problem: The oil cooler will get clogged with particles, decreasing its effectivity and inflicting harm to the gas system and EGR cooler.
  • EGR Cooler Problem: Much less coolant flows to the EGR cooler when the oil cooler is clogged. This causes it to overheat and doubtlessly leads to head gasket failure or coolant leaks.
  • EGR Valve Problem: The EGR valve is susceptible to clogging from soot, which causes poor efficiency and requires frequent cleansing.
  • VGT Points: Soot buildup within the VGT causes it to stay open, impacting throttle physique response and turbo spooling occasions.

  • DPF Points: Diesel particulate filter will get clogged, reducing engine energy and efficiency.
  • Cracked Pistons: Pistons crack when the engine is pushed exhausting for a very long time. Apart from, the manufacturing unit head bolts have a tendency to interrupt at round 600 RWHP attributable to a design mistake made by Ford.
  • Oil Cooler Points: The oil cooler fails repeatedly, inflicting engine overheating, and expensive alternative.
  • Poor Gas Financial system: The design situation causes the 6.4L engine to make use of extra gas in gradual site visitors.
  • EGR Cooler Problem: The EGR cooler situation from the 6.0L engine persists within the 6.4L engine.

Aside from these issues, the Powerstroke house owners have additionally reported some much less widespread however expensive issues.

Like, because the chaffing of the high-pressure oil pump wires, leaking via the entrance cowl, acceleration points, clogging of the fuel-water separator, and so forth.

Supply: Diesel Army

The widespread points with the primary era were-

  • Radiator Leaks: The Powerstroke 6.7L has two radiators and house owners typically face issues with the first one. The radiator typically leaked inflicting the engine to overheat.
  • EGR Cooler Clogged: The EGR cooler within the 6.7 model exists to fulfill emissions requirements, however it could possibly change into clogged with carbon and trigger larger emissions, overheating, stalling, or engine failure. 
  • EGT Sensor Malfunction: The 6.7 Powerstroke engine has 4 EGT sensors, which might fail for numerous causes, together with all 4 without delay. 
  • Turbocharger Issues: The Powerstroke 6.7L is a robust engine with excessive output. Nevertheless it had a weak ceramic bearing that will break too typically below strain.
  • Injection Pump Issues: Injection pump failure was a standard drawback within the first-generation 6.7 Powerstroke. It was triggered by means of the fallacious injection pump, the Bosch CP4.2, which was not appropriate for the engine.

Supply: Diesel IQ

  • Failure Of The CPS (Camshaft Place Sensor): The 7.3L Powerstroke engine had points with the CPS. A failing CPS could cause the automobile to not begin or stall.
  • Turbocharger Up-Pipe Leaks: This engine experiences failure with the turbocharger up-pipe, inflicting a lack of increase and doubtlessly elevating exhaust gasoline temperature.
  • Noise:  The 7.3L Powerstroke made an unusually loud noise, and the foundation trigger remained unknown. Nonetheless, some individuals speculate that the split-shot injectors had been chargeable for this situation.
  • Gas Filter Housing Leaks: The gas filter housing leaks attributable to cracks within the gas bowl or filter housing. Most individuals might want to take their automobile to an expert for restore, as it may be tough to repair your self.
