Can I tell with the engine number whether IMS is problem?

[10/10ths]

....I bought a 2004 Boxster S "50 Years of 550 Spyder Edition" in 2015.

She had only 25,000 miles on her.

I shipped her on a flat bed to Flat 6 Innovations and had Jake Raby install the "IMS Solution" plain bearing that Jeff talked about above.

The car now has 45,000 miles on her.

I've driven her 20,000 miles on the "IMS Solution" in two years.

My original IMS was absolutely fine.

I am still absolutely thrilled with my decision.

Just factor in the cost for an IMS Solution retrofit into the purchase price of the 986, no matter what the vintage or mileage and start enjoying these wonderful machines.
