Possibly. BMW and others all tried the same technology and all had the same issues. The fuel should have been OK by then but I wouldn't want to bet how pure it was.

A cylinder that fails due to petrol can only be described as crap.

Hi sulphur content in the fuel was the main cause of the issue. Well reported failures in both BMW engines and early jags.

Funny that high sulphur petrol did not seem to damage Nikasil or Alusil used on Porsche engines.

BMW would replace the block if it failed and that didn't have the issue so there must have been something wrong with the linings as the later/replacement ones were fine.
I had a 996 C4S, they have their own special way of ruining the bore linings! Mine was fine (just to be clear) but I remember a lot of forum guys experiencing issues with bore scoring.
Also, I got talked into the LN Engineering ceramic IMS bearing, now that really is a pile of ****e! £600 for the bearing, lasted 5 weeks and was leaking oil through it. Warranty is a US one so it's 30 days! Euro Car
You may be wondering why I changed the bearing in the first place. Well, It was part of the purchase of the car and it needed a new clutch and flywheel so while it's off, you may as well... Yeah, wish I hadn't.
