A Kansas mechanic has received a 100k-mile Porsche Macan S that he says is so screwed up, he has told the customer it is dead.
Mechanic David Long, aka the Car Wizard, has received a 2016 Porsche Macan S with one problem; however, it is a big problem, he says, that spells the end of the car.
That problem is a really bad knocking sound, and the cause of that issue means this Porsche SUV can go no further.
That feels like a great shame, given that the car, for the most part, is still in good condition.

What is wrong with this 2016 100k-mile Porsche Macan S?
At the heart of this car is a loud knocking sound that can be heard coming from the Porsche’s engine bay.
The Car Wizard says if it were an intake problem, that wouldn’t be too bad.
But that isn’t where the problem is, and after starting the car up, the loud knocking sound is very evident.
Initially, the Wizard states that many9 would believe it was a simple lifter problem.

However, a call to a fellow mechanic suggested that it could be an issue within the cylinder bores.
These could be scored/marked, and this is due to poor maintenance and a lack of an oil change.
With higher revs, the noise is even worse.
Poor maintenance has mechanically totalled this Porsche.
The Car Wizard says you can get used engines for these cars, but they cost up to $10,000.
Add in the extra work involved, and the repair bill for the customer could rise even higher.
At that point, it becomes much cheaper to just scrap the car and buy another car.
Other YouTubers have shown that there are real bargains out there.
The Car Wizard and his team check out one of the bores after removing a spark plug.
The deeper they go, the worse it becomes, and the scoring is incredibly deep.
It has worn through the coating and to the aluminum of the engine block.
With that wear likely in the other bores, it is obvious why this car won’t go any further.
The moral of the story is to always keep on top of your car’s maintenance.
