Let’s be clear right here, and never for authorized functions: No engine is ideal, and all engines can fail catastrophically earlier than fairly anticipated. Ford’s 6.2-liter V8, also referred to as the Boss engine, was in manufacturing from 2010 till 2022 and principally utilized in its Tremendous Responsibility vehicles. And it’s nicely regarded for its sturdiness and reliability, largely as a result of it does not have many frequent faults, and might take loads of bodily abuse.
So far as Ford engines go, it could be one of many firm’s finest fashionable efforts. Nonetheless, Eric from the I Do Vehicles YouTube channel discovered one which was criminally uncared for and horribly maintained on the similar time. As is customary from Eric, he pulled the engine aside to search out the foundation of went incorrect. And rather a lot went incorrect.
Busted Spark Plugs
On the prime of the engine, we’ve what Eric describes as “malice within the combustion palace.” Some plugs have huge gaps means out of spec, and a few are merely smashed to bits. The consumption is stuffed with the type of high quality particles you would possibly discover swept up in a machine store dustpan. There’s particles within the valve guides, a few of which aren’t connected to the cylinder head anymore. At this level, we are able to assume that the motive force skilled loads of rattling for a couple of moments, then an enormous shudder because the engine catastrophically gave up the ghost.
That is confirmed by one of many 4 pistons on one financial institution not being a whole piston anymore, and a complete piston lacking on the opposite financial institution. The engine definitely skilled a detonation incident, possible stemming from a scarcity of lubrication over a protracted interval. What’s left of the connecting rods, pistons and rings are within the oil pan. After draining the remaining oil, there’s simply increasingly shrapnel to be examined. It is like a freaking tesseract of carnage, rising in measurement the deeper you go.
An Costly Detonation
Given the quantity of shrapnel within the pan, Eric theorizes that the engine’s excessive cylinder deactivation occurred whereas it was at low RPM and pulling one thing. Taking a look at how darkish one of many combustion chambers is, we’d guess that it was consuming loads of oil, however the proprietor wasn’t on prime of it, and simply stored on ignoring the temperature dials till the engine had nothing left to present.
The oil pump could have failed, however the consequence is similar both means – low compression, little lubrication, loads of warmth, and a horrible demise rattle because the engine transitioned from a working 6.2-liter V8 to a non-functional six-piston engine in a matter of seconds.
Our greatest guess is that the engine got here from a fleet truck that wasn’t nicely maintained. We do not know the mileage, however the common situation means that it had led a helpful life earlier than its demise blow. We won’t assist however assume there have been loads of warning indicators and large pink flags earlier than it let go. That additional helps the fleet-vehicle concept, as the motive force possible wasn’t personally invested within the truck’s well-being. And by ignoring the warnings, this driver possible spent a while on the aspect of the street, ready for a tow truck.
