How reliable is the Ford 5.4 V8?
It is relatively reliable, with only two major faults: excessive timing chain stretch, and spark plugs sometimes blowing out of the cylinder head. I’ll cover the spark plug issue first. Depending on how you look at it, there are either not enough threads in the spark plug holes, or the spark plugs were too short.

what years should I avoid? The only one to really avoid is the 5.4 3v Triton which was in the F150 from 04-10. The smaller 4.6 Triton doesn’t share any of those issues and, while not as fast, is very reliable.
What year did they fix the 5.4 Triton?
Most everyone in the know, including me, will not purchase a Ford with a 5.4l 3v engine, because of the timing hardware issues. Ford did fix the two part spark plug design on or about 2008 (its is reported).
Which Triton engine to avoid?
The 5.4-liter Triton engine is a member of Ford’s Modular V8 engine family, introduced in 1997. The three-valve version produced from 2002 to 2008 is the most problematic and one of the most unreliable Ford engines. Although it produced decent power (295-390 hp), the engine had several glitches.
Is the Ford F250 5.4 a good engine?
The Ford 5.4 Triton has proven to be an impressive engine that delivers a good balance of performance and reliability. However, there are certain areas in which it can fall short. One of these areas concerns the timing chain, timing chain tensioner, and cam phasing system.
What years did the 5.4 have spark plug problems?
One of the common issues of the modular platform was its tendency to blow out spark plugs. This issue happened the most on the 5.4 Triton from 1997 to 2003. During this era, the motor commonly powered the F-Series pickups, E-Series vans, and the Expeditions/Navigators.
