"The critical point to note is that it should be replaced as early as possible in the life cycle of the engine "
And in a perfect (Porsche) world we would love to know how to time that so perfectly !
Pray tell us !
This is a reality thread. It is about mitigating risk. And as far as cost is concerned a good total rebuild from IMSB failure is $7000+. And that is just parts and equipment-assuming the engine can be saved.That is the number that matters ,not the $10 for the bearing.
So discussing any cheaper option = be it The Solution or a cylindrical roller bearing like NUP204 is obviously valid. Replacing with the same failure prone part when we are still discovering causal factors does nothing to mitigate risk.
And it is runout not out of round. The 2 are obviously different. The IMS is bent not squished.
