The Death Knell of Rod Knock
There are several tell-tale sounds coming from Ford engines that can provide a pretty accurate diagnosis for an experienced mechanic---without even having to disassemble the engine. Caught early enough, recognition of the beginning of an odd engine noise can result in avoiding total loss of an engine. However, when it comes to the sound of the death knell of rod knock that “tolls for thee” nothing good can come of this. It’s often just too late for both you and your vehicle.
However, if there is one silver lining to be had when it happens to someone else, it’s that it serves as an excellent lesson of why your oil and filter have to be changed regularly and what happens when you don’t.
That’s the message in a recent FordTechMakuloco YouTube channel episode where the host---Brian---does a quick tear-down of a Ford Expedition 5.4L 3-valve Triton engine that has literally been sludged to death due to owner neglect.

The Value of This Video
The value of this video is that it is about as a strong reminder as any of what can and does happen to an engine that is not properly cared for and maintained as it should be. In particular, how excessive sludging inside an engine affects oil pressure and can starve your engine’s bearings to the point where lubrication is so low that the bearings literally grind away to nothing.
That said, here is an important video to emphasize the importance of car and truck maintenance and why it is so important to change your vehicle's oil.
