The 2.4/2.7L Toyota engines are known for their extreme longevity, and there are even some reports on here of 3.0L V6's pushing over 250k. After hitting 150k today in my truck, I am curious how much longer other 3.4L's have gone without being rebuilt. I drive the shit out of my truck, about 3k a month and it still feels as strong as the day I bought it at 92k. Should I start saving up now for a rebuild?
