IMS failure - how can I confirm my engine is toast?

[Perfectlap]

What is the build date? some of the first 2005 987s had the old bearing. But the revised bearing very rarely see failures. Also, the IMS is often blamed as the root of the failure when its actually something else entirely.

Cheap and easy thing to do.

An oil analysis would be a waste of both time and money. Pull the sump cover, if it is loaded with ferrous grit and debris, it is over, the engine needs to come out and apart. Takes about 15 min. to do and you will know exactly where you stand.

Did you use a sealed bearing when you replaced the IMSB?

I did. I researched bearings and found that "fully sealed" bearings are available. I chose a fully sealed high temp steel ball bearing. The grease, and more importantly the seal material (Viton) is upgraded in this bearing. In a fully sealed bearing the side shields touch the inner race.
