I know the engine used in the VX has a history of problems including premature failure and high oil use. I have read that there are some theories about the cause.

It appears that many engines were replaced under warranty, presumably these would have been new factory engines with whatever flaws were in the original engines.

It appears that many engines were replaced with used engines from a variety of sources which again would have had the same inherent problems.

It appears that many engines were rebuilt or repaired by a variety of local shops.

I saw a comment the other day that assumed that rebuilt engines would not have these same issues.

I wonder if it is true that an engine remanufactured by an engine specialist who tears the whole thing down and replaces major parts to spec would provide a better engine that OEM.

Does anyone have any experience along these lines?
