If I'm getting this right, the IMS bearing "might", fail, but the bore scoring will definitely happen with age?
I was looking at a 996, but even if it's had the IMS bearing work done, it's still going to fail later on if it's gone over 100k miles
Plenty of cars out there have done well in excess of 100k with no issues, as with every engine they will all fail at some point!If I'm getting this right, the IMS bearing "might", fail, but the bore scoring will definitely happen with age?

There are 996s and 996s. Early cars (996.1 with the "boxster" head lamps) have a 3.4l engine with a sometimes vulnerable ims bearing, but don't generally bore score. As a rather crude rule, most of these are now past the point of premature failure. If I'm getting this right, the IMS bearing "might", fail, but the bore scoring will definitely happen with age?

Later cars (996.2 with the "turbo look" head lamps) have a 3.6 or 3.8l engine which seem to bore score with age and mileage more frequently than you'd hope. Some of these failures are premature (ie well under 100k miles). Ims bearings can be problematic but later cars have a stronger bearing.
These are gross generalisations. Although the cause of bore scoring seems to be related to design and specifically cooling, the unpredictable nature of failure suggests there is something else at work as well - fuel, usage, manufacturing batches, who knows? The same might be true to some extent with ims failures but the nature of the failures seems less common and more random.
The best you can do (IMHO) is buy the car you like on the understanding it's a bit of a lottery. The odds are in your favour and seem to vary depending on the specific model, but "it could happen to you" so go in with your eyes open.
There is another very sensible alternative to consider - taking out some protection against the full cost of a repair in case it happens to be necessary during your ownership.
There are several available among which is our own Lifetime Maintenance Plan which for a monthly payment covers the full cost of annual servicing and MOT's (so you always get something back), the labour cost for most repairs (even wear and tear ones) and also covers the labour cost of an engine repair (which is a large proportion of the total) - and it also accommodates other upgrades during a repair for just the parts costs (where relevant) - see www.hartech,org.

Thread revival I think. Had a rebuild last year due to engine seizure down to mechaninc who had the car and now the cars broken down again after 1500 miles give or take with a judder and oil light flashing and stalled with a puff of smoke in 2017
And it's a Carrera 3.4 996 x reg
Started up to make sure and it was pouring out with smoke ??

Most rebuilds offer at least 1 year warranty. I do hope your warranty still not expired and ideally you should go to the mechanic who rebuilt it. It could be anything, they are very old cars nowadays. Good luck!Carrera 3.4 996 x reg

Just my luck that the 1 year is up and the guy that did the job died the year we got the car back. He tried to say the egr was knackered and I told him these cars don't have an egr valve. He was persistent to charge £200 for one but never got that money for it as it doesn't exist.
