Ok, so a I've been watching quite a few threads where lots of us have had this problem. Their VX shows symptoms: It drinks oil. No visible signs of leak. It begins to knock. Then it goes. Boom.

The problem has been attributed to faulty piston rings. Not all of the engines have the problem, but obviously we should all have cause to worry when we get near to 80k miles.

Here are my questions: Why can't we just fix the problem? I mean, if we start to show symptoms, why won't Isuzu crack open the block and fix the problem? It would certainly cost less than replacing the whole block, right? Or would swapping out piston rings be an admission of guilt on their part? If you could have the piston ring problem fixed for $1000, would you? I mean, a thousand bucks to save a possible $5000 failure?
