IMS Problems and failures

[san rensho]

Is there any known correlation between IMS failures and climate? In other words, do cars in the north, that get put away for part of the year and drive more in the cold tend to get more failures than cars in the south?

This gets beat to death so much and there is stillno smoking gun. But the positive takjeaway from every discussion is the low incidence of failures

+1. Everything you read in the thread is pure conjecture. No one, including the two guys who provide the replacement bearing, will give you correlation information.

I've thought about this lately. Good weather like in SoCal tends to result in more frequent driving, year round. That has to be a good thing for an engine that gets stronger with more exercise.

There's no KNOWN correlation between IMS failure and anything. There are too few to make any correlation to anything. Everyone who worries about this has a spin on the question - driven too hard, driven too soft, manual, automatic..... Again, not enough to establish any specific pattern and some go undiagnosed completely. Just drive it and don't worry......... that is known not to help anything.
