Causes of Rattling Noise in 5.4L Boss Engine

The 5.4L Boss engine that comes in the BA BF and FG models can often be heard with having a rattle. This could be one of two things, and it is important to have a careful listen to the engine when purchasing a vehicle fitted with one of these engines in it.It is very common for the timing chain guides to wear in the early models of the 5.4L Boss V8 engine. This can cause a rattling sound, most commonly heard when the engine is cold coming from the front of the engine. In order to eliminate this rattle, the timing chain as well as the guides will have to be replaced, which isn’t a small job due to the whole front of the engine having to be pulled apart.

Another issue that causes a rattle is the starter motor not disengaging once the vehicle has started. That will cause excessive wear on the starter and also the ring gear. This is a much easier job to fix as it is only the starter motor that will need replacing if it isn’t left for too long.

These are both things to listen out for when purchasing a vehicle fitted with the 5.4L boss engine, especially the earlier ones. We can supply and fit replacement boss engines or starter motors if you do experience any of the above issues with your car.
