The IMSR bearing looks fine and feels fine.. It faired better than I would have ever imagined seeing how much foreign object debris was in the oil. The IMSR bearing has a very low tolerance for contaminated oil with ferrous material as it is an open bearing with close tolerances.
This IMS bearing will add to our data base due to the mileage and the severe shock that it experienced, endured and lived through. It can't get any worse.
Here are some pics of the teardown post-mortem.
Now here is what was lurking as a totally unrelated issue just waiting to fail... When we pulled the engine from the car it had some coolant in the oil and vice versa but it was yet to mix.. Upon teardown this is what a trained eye found.. A classic
This is a magnetic drain plug.. Whats attached to it is the rod and main bearings. The IMS Guardian would have saved the life of this engine undoubtedly.
The entire engine is grenaded. The crank is trash, carrier is trash, all the rods, the oil pump, one cylinder head and the scavenge pumps. The IMS tube and IMS bearing are all thats really left, even the case was damaged.
