2UZ is the best engine Toyota ever made.You know how many land cruisers in the Middle East crossed that threshold right?
It's not even an event.
Most of the ones that end up reaching high miles without much engine work are almost always 2uz rigs
1fz would ahve been rebuilt a couple of times before its first mil on average.
Meanwhile some new American and Japanese built twin 6 3.5 v35A are going out before even reaching 50k kms
