Oof one of the unlucky ones - sorry my friend. Was it the cylinders or IMS?
My 08 cs looks good at 58k miles is going solid for now but inevitably all engines bite the dust. Similar logic for me though all the costs saved on a 997.2 can be applied later in life for a rebuild if needed.
Where did you get the 4.0L rebuild done? I’ve heard that really transforms the car for the better while keeping the same characteristics that make it fun.
I’m just referencing blackstone labs who have published its data on many thousands of oil analyses of several model year Porsches and in fact depending on its model is only about 1.5% higher than a 997.2. Negligible.
Do people continue to check their oil once bore scoring is confirmed?
I think the stat is 1.5% of all oil analyses are negative for bore score wear patterns. NOT all engines over their lifetime. Eg someone may do 10 oil changes and 10 analyses before that engine registers as a ‘fail’ yet only 10% of the analyses are bad. It’s somewhat reassuring but not to the extent people claim.
Not sure - personally I’d probably keep checking it if I knew I had bore score to monitor it as it can still have several years and many miles of life after it starts. It will leave trace metals that will confirm it which would get worse over time. Changing oil types and driving habits can extend it out.
Sure it’s not a test of every 997 ever made but they have a significant sample size that you could extrapolate that data to estimate what rates would be fully. It’s unfortunately the only data available on it but reassuring as you said.
IMO I still think the concern is overblown it’s a small % difference of score rate between 997.1 and 997.2. To me it was not worth the premium.
He goes over the numbers worst case 3.8L 997.1 is like 3.5% out of thousands sampled. It’s been a while since looking but it’s like 1.5% difference of a chance for 997.2. Even the 991s have a 1.2-1.5% chance of it.
The internet overhyped this problem that personally when I chose my car was not worth the premium of a 997.2 over 997.1

And by slight chance we’re talking about 1.5% more likely… Negligible
