Is there more information to be had about this problem generally?

I bought a 2012 C70 T5 a few months ago, and I'm starting to feel glad that I sprang for the CarMax extended warranty.

Do we have an analysis on root cause? Are we sure it's bad rings? Bad how, exactly? Cut the wrong size? Inferior alloy? Factory robot installed them wrong?

Do we have any information that would lend itself to identifying which engines have this problem and which do not?

Resurrecting an OLD thread...

- I have owned P80, P2 cars, so familiar with Volvos.

- For the newer models, let's say 2012 T5 engine, does anyone know the EXACT ROOT causes of engine failure at 80K-120K?
I am asking bc I am looking ahead in case I need to buy a more recent models such as 2012+ cars.

- Also, what is the BEST engine/trans combo for 2012+ Volvos?

Thanks!

Long oil drain intervals, especially with warm up idling, leads to sludge in oil ring grooves and the low tension rings will not power through the grip of the deposits. It is far from a sure failure. The repair is to put the same rings back in this engine. 3.2 and 3.0T engines are pretty dern good. There is a new oil spec, SN plus, that is developed for this oil sludge, stuck ring, oil consumption and detonation that can break center electrode of spark plug. Ceramic electrode bits can scratch the cylinder and then it is done. The electrode fracture is way less likely to occur on the 5 and 6 cylinder but is a bigger risk for the 4 cylinder Drive E motors. The higher compression used on direct injection pushes the detonation issue when the oil in combustion chamber.
