One of the "changes" was that the area around the #4 cylinder intake gets a lot hotter, ruining the gasket.

Also, it also just occurred to me that the 93-01 Altima probably uses some close variation of the 240SX engine rotated 90 degrees and mounted to a FWD transmission. I was always under the impression the KA was a very reliable motor...
I'm not sure why the engine's reliability rating would change from year to year, but I'm just citing what I saw on Consumer Reports. It wouldn't surprise me if Nissan made minor adjustments each year, but the engine was rated to be very reliable pre-2000, decent in 2000, and to have major problems in 2001. Seems a bit odd.
