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.
Interestingly enough, blowing out usually happens on the passenger side with the spark plugs on the third and fourth cylinder. It was one of the problems related to the first issue (the ignition system problems) I mentioned in the article.
Furthermore, it is not unheard of that a blown out spark plug breaks the ignition coil on the “coil over spark plug” design. First of all, a blown spark plug will completely strip the threading of the aluminum head. Later on, they have the exact opposite problem (bear with us for that one).īlowing a spark plug on the 5.4 Triton engine can have some serious effects. We could even call this problem a common one for the Triton engines produced prior to 2004. Regardless, exactly this happened to some 5.4 Triton engines right from the start in 1997. Blown Spark Plugsīlowing spark plugs with the engine running isn’t exactly what you would expect to happen often.

Thus, a full engine inspection should be performed.Īs noted above, rattles, strange sounds, and a rough engine start are the most common symptoms for timing chain, tensioner, or cam phaser problems. This can lead to premature camshaft lobe wear, more stress on the cam phasers and, in the worst case, physical contact between pistons valves and other metal pieces. If some of the most important supporting pieces of the timing chain have been damaged, we should infer that the ignition and camshafts timing isn’t in accordance with the factory setting. Plastic pieces, on the other hand, can fall to the oil pan and partially block the oil’s path. No reason to tell you that this can damage the timing chain further. 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. The loosened timing chain will rattle like mad and damage plastic timing chain guides. In this case, the domino effect is more than likely. If you can hear rattles, the timing chain may have become loose due to the blown out tensioner. So, listen carefully for any unusual rattles after a cold start. Timing chain rattles are most noticeable at the very start.
Having all these parts working correctly is crucial as all of them affect moving parts of the engine and, more or less, keep the engine from tearing itself apart. VVT hasn’t been installed in older 2 valve motors. Bear in mind that cam phasers are part of the Variable Valve Timing system which is an important component of the 5.4 Triton engine with 3 valves per cylinder. 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. The engine sounds strange? You can hear a lot of knocking noises on acceleration, cold startup, or when you let off the throttle. Timing Chain, Tensioners, and the Variable Valve Timing Problems

After Ford recognized this problem, they offered a slightly redesigned replacement part which is not in direct contact with the steel frame. Sure, without fuel, that mighty Fort Triton won’t work.Īs the fuel pump driver module is attached to the frame (at the rear end) with only two screws, replacing it is a DIY job. 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. 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. In the first place, the problem happens because the fuel pump driver module is directly attached to the steel frame. This tends to happen on Ford trucks driving on highways (I don’t have to stress that losing power there is super dangerous). Failure of the fuel pump driver module usually cuts off the petrol feed to the engine which, of course, causes the engine to turn off, thus cutting power to all essential systems. This problem is typical for the Ford F-150 with a 5.4 Triton engine. 5.4 Triton Engine Failure of the Fuel Pump Driver Module
