Common Issues with the Ford 5.4-Liter Engine

One of the most significant issues with the 5.4-liter engine, particularly in the 2004 to 2008 model years, is the notorious spark plug blowout problem. In recent years, the engine’s design has made it prone to blowing out spark plugs, leading to costly repairs.

A case study from a mechanic in Texas reported that many customers with these model years sought repairs due to excessive engine noise, indicating that the tensioners were failing prematurely.

Oil consumption issues have been reported in the 2005 to 2009 model years. Many owners noticed that their engines were consuming more oil than expected. A Ford Truck Enthusiasts forum survey revealed that 70% of 5.4-liter owners in this period experienced some form of excessive oil consumption.
Years to Avoid: The Evidence

While these years were praised for their performance, they also had several reported issues, particularly with spark plug and oil consumption. Data from Consumer Reports indicated that owners of these models reported more engine-related complaints compared to other years, making them less desirable options for used buyers.
