If you were in my shoes, what would you do?

I think you should get the IMSB done.
If you're going to keep it, you could easily get another 100k out of that engine.

I've had mine done and one big advantage is that I enjoy driving the car so much more, now that I'm not always wondering in the back of my mind about the IMSB destroying the engine.

Just picture yourself being in the middle of nowhere with a detonated engine. That would be a bad day. I know it can happen anyway but, I feel a lot better with that extra insurance.

Hope that helps!

Just because you have a high mileage engine doesn't mean your home free with the IMSB. Partial bearing seal failure is one of the main reasons IMSBs break. Leaking seals allow oil to wash out the bearing's grease over an extended time period, but the oil flow through the leaking seal isn't enough to fully lubricate the bearing.

Low mileage cars see more failures because their seals sit in acidic oil for extended times and degrade. For various reasons, seals degrade more slowly in high mileage cars so one sees failures happening less. Eventually, high mileage cars will see problems too its just nobody seems to know when.

If you do nothing else, it's probably a good idea to remove the outer seal of the OEM IMSB when your in there changing the clutch. Personally, I wouldn't and didn't stop there when I changed my clutch. If your doing the work yourself, it just the cost of parts that you're saving. I'd bet some Forum member would be willing to lend or rent the special tools to you.
