Scaremongers like you just feed the IMSB replacement industry (who also don’t disclose the condition of the bearings they replace). Does anyone even know if the LNE replacement is a permanent fix or will these engines need pulling apart in a few years too?

I clearly stated that I might get mine done when the clutch needs replacing for my peace of mind which you disagreed with. My car has done 80k, has an oil change every 5k miles and filter checked for particles, driven as recommended etc and had no problem with the engine exploding getting to work today or the previous 10 years for that matter. Porsche had to admit there was a design issue but only in the US due to the blame culture, they have not offered to modify every affected engine free of charge, have they? There may be a minority that continue to experience failures so every owner will have to weigh up the risks but there are things like regular oil changes that you can do to reduce it.

Toyota allegedly have a 3.7% catastrophic engine failure rate and other manufacturers have similar rates but you never hear the hysteria like you do on Boxster/911 forums (Honda are best with 1 engine failure in every 134 cars).

While I agree with this, if the IMS failure caused the engine to catch fire in some cases or caused a rear wheel to fall off occasionally, every Boxster made would have been recalled. Remember the Ford / Firestone issue? How many tires actually failed? It depends on the safety of the occupants when the failure occurs.
