Bore scoring on my Macan!Little hard to accept that a 5 year old Porsche with 76k miles developed this condition.
Porsche's initial reaction = out of warranty.
New engine is about 22000.00 installed and running and being only 5 years old there are very few in scrap yards
to find a used engine.
Owning a '99 Carrera with 126k and a Cayenne with 161k miles (yes I drive my cars!), I have to say this is a huge
disappointment to have the Macan self destruct like this.
The Lokasil liners are such crap.

very sorry to hear this. are the pictures of the cylinder walls or the pistons?

pszikla

On cylinder walls #4 and #6.

Holy Crap! That's pretty bad. Sorry for the situation. At least Porsche has it figured out which cylinders to score. How did #5 look?

pszikla

Just those 2 cylinders on bank 1.

just curious what prompted the scope to be done in the first place?

It was a progressively increasing ticking sound, much like in the "old days" when you had a bad lifter or loose rocker arm on north American engine.

I wonder how prevalent it is across the board. It seems ridiculous for a 5 year old car.

I seem to recall that Jake built a V8 or two for a Cayenne - not surprised that any Lokasil lined cylinders are failing like this.

Any thoughts about having Nickies done? Figure labor and parts would HAVE to run less than the $22k quoted and you'd have a better outcome?

TexSquirrel

Does Jake rebuild Macans?
If so, I’d go with him.

Wow! Sorry for your misfortune That blows big time! I wonder if LN Engineering has developed Nickie's for that motor. Not that it helps now, but I would suspect/have a look at the injectors on those cylinders - I bet they're leaking. *** Just for posterity - I thought cylinders 4&6 are bank 2? I realize the Macan is a V-6 and the motor is in the front, but that shouldn't impact the bank #'s should it? Bank 1 = cylinders 1,2,3 Bank 2 = 4,5,6... ? Good luck whatever you decide to do.

This isn’t new with the Macan.. Seen this since the year they were introduced.
Nickies are an answer, but like the Cayenne, these cars are often not regarded enough by their owners to spend the required amount for a be all, end all fix. There’s little to gain for the development that has to go into it..

Flat6 Innovations

No. I decided not to work with these. Too many people regard them as a throw away car if something significant happens, just like the Cayenne.

I just saw as case of this the other day on p-tech's channel perusing youtube.


Seems like this is becoming more common on macans. I was considering a second hand macan or cayenne as a daily, but I think this is enough to deter me even if it was CPO. As Jake indicated people treat these as throwaway cars.
