What Ford Diesel Engines To avoid?

Ford Powerstroke diesel engines are quite popular and reliable. But among them, try to avoid 6 L and 6.7 L Powerstroke engines. They have a few issues, which are briefly discussed below.

Ford Superduty 6 L is a powerstroke diesel engine by Ford. It is known as six leakers. This one had a few significant issues from the year 2003-to 2007. One of the major problems is its EGR system. There are a few more too.  

Reasons To Avoid Ford Superduty 6.0 L

There are a few problems with this engine. And they are-

  • Head Gasket Failure: The main issue is that the head gasket boils down to the TTY head studs.
  • FICM Failure: Fuel Injector Control Module supplies solenoid voltage. But engine heat causes damage to the FICM, and thus it fails.
  • Oil Cooler Issues: The oil cooler in this engine isn’t proficient. Dirt gets clogged on the oil cooler now and then.
  • EGR Cooler Issues: If the oil cooler gets clogged, it increases the EGR temperature too. That is how the EGR cooler fails.
  • EGR Valve Failure: The valve regulates the exhaust gases. As this does not function very well, the soot from exhaust gases can clog it and cause failure. 

These are the main reasons you should avoid the Ford Superduty 6 L engine.
