I've changed the oil at 5,000 mile intervals since I bought the car with 10K miles on the dial. At 100K, four changes ago, I found one small shinny non-metallic flake in the filter. It was 1/8" or smaller in diameter. Since then all of the changes have been clean, that hasn't been any visual evidence of metal in the oil stream. I am not considering an engine rebuild at this point, just an IMS replacement. I'm aware of the risk, but that's a chance I'm willing to take.
So here's my question. Assuming price of the part isn't a concern, would you recommend replacing my single row IMS with a Gen 2 Pro or the IMS Solution. The difference as I see it is that the Gen 2 is an unsealed design which may become damaged and fail completely if metal flakes show up in the future. In contrast, I'm guessing that the Solution would fair better because of its plain bearing design and the engine wouldn't self destruct due to a collapsed bearing if the Solution became worn.
Thanks

The answer to your question depends upon where you head is at; if you plan to keep the car for a long time, the Solution (which is the only permanent fix) would be the choice, if you plan to only keep the car for a few years, the Pro (which has to be periodically replaced) would make more sense.
We have a 2001 car in the shop right now that has less than 12K miles on it and looks like it just rolled off the show room floor. The owner, who bought it new and keeps his cars a long time, did not hesitate for jump for the higher priced solution when the car was done, and I agree with his choice.
One other point to remember with your car is that you may also have a dual row OEM bearing, which further narrows your choices, but also tends to be the least problem prone style bearing.
