Still, I'll start and drive easy to operating temps based on the consistent feedback here.
Like any good disaster, it’s often multiple factors combined that causes a crisis. Bore scoring probably requires many things to line up: cold climates, hammering the engine when it’s cold, low revs, changes in fuel (fuel formulations that have changed since the original design of the engine), the horizontally-opposed engine layout (and consequently lubrication differences between the banks), and bad luck - all play a part in this drama.

Based on what I have read:
-PDK cars when driven in "standard mode" exhibit more bore scoring
-cars from northern climates have this issue more then others
-idling / short distance driving combined with prolonged oil change intervals is a recipe for scoring
-not getting the oil / engine hot enough during drives
-poor coating / porsche design on 9A1 engines - not a problem on turbo motors
Personally would look at 2.5T Cayman / 718....

Hey there - I'm interested in a 2013 PDK coupe, 22K miles on the odometer, and on inspection by an independent shop with a scope that a couple of cylinders have the dreaded bore scoring.
(Yes, yes, I did a search of this forum and didn't find anything.)
The price seems right at $60K, but this has got me kind of backed off. The car runs and drives great and I'm concerned but not enough to fully back away.
Is this like a time bomb? What's it cost to drop in a new engine?
Thanks in advance.
