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
