Prior to this, the only viable solution was to actually replace the head altogether.

It was a popular option all the way from its inception in 1996 to 2010, in all of its iterations.

Today, it is still one of the most alluring options on the used car market, but before you start searching for the perfect driving mate with a 5.4 Triton engine, some important pieces of information should be taken into account.

Heres a list of 7 common problems the 5.4 Triton engine may face, which potential buyers might want to take a look at before purchase.

It seems that problems with the ignition system did affect all versions at one point in time.

It is not unnoticed that some of the coils can fail internally due to liquid penetration.

As its surface is exposed to the elements, salt, water, and dirt build up on its aluminum casing and cannot be washed away as it is in contact with the steel frame.

Over time, vibrations, salt, and water do irreparable damage to the casing and dirt enters the driver module causing short circuits and making permanent damage to the smart junction box.

After Ford recognized this problem, they offered a slightly redesigned replacement part which is not in direct contact with the steel frame.

While causes for such sounds can be numerous, owner experiences have shown that the most likely reasons can be blown out tensioners, a loose timing chain, and cam phaser breakage.

So, listen carefully for any unusual rattles after a cold start.

If you can hear rattles, the timing chain may have become loose due to the blown out tensioner.

The loosened timing chain will rattle like mad and damage plastic timing chain guides.

These plastic pieces can become fully detached from metal surfaces over time thus enabling metal-to-metal contact of the timing chain and metal carriers guides were attached to.

No reason to tell you that this can damage the timing chain further.

Plastic pieces, on the other hand, can fall to the oil pan and partially block the oils path.

Regardless, exactly this happened to some 5.4 Triton engines right from the start in 1997.

We could even call this problem a common one for the Triton engines produced prior to 2004.

Later on, they have the exact opposite problem (bear with us for that one).

First of all, a blown spark plug will completely strip the threading of the aluminum head.

Furthermore, it is not unheard of that a blown out spark plug breaks the ignition coil on the coil over spark plug design.

It was one of the problems related to the first issue (the ignition system problems) I mentioned in the article.

The problem was so common that numerous aftermarket specialists did, in fact, provide tools and solutions to drill, retap, and rethread the spark plug hole in the head.
