Worth it to 'check' IMS bearing during clutch? Clutch recommendations?

Unsure, but I should call LN with the number and see what the date was Do these bearings 'wear out'?

Then you have a bit more room to inspect the bearing. You can stick your finger or a small piece of rag into the hole and see what you got. If you find oil and no metal debris, there`s not much to worry about.

Is this applicable to 99?

Yes, all IMSBs wear out. It's just a matter of when. If you're going to track the car, then perhaps you should install LN's IMS Solution. It's the most bullet proof of them all.

Just for clarity...the car already has LN's IMS Solution, installed by one of the previous owners at unknown mileage.

Are you suggesting to preventively reinstall another?

Otherwise, what mileage are they good for?

The warranty is only good for 5 years, regardless of mileage.

That sounds like a better warranty than Porsche's standard powertrain warranty.

Yes, but Porsche never claimed that the car was a "permanent solution"

I have $45 brake pads on my Subaru with a better warranty.

Actually they did (indirectly) as Porsche considered the IMS was a 'Non Serviceable Item' which (by the way) you could not buy from them by itself.

The IMS Solution does not need to be replaced, ever.

Repeat of post 25.

I think it is. Mine is a `99 Boxster with a dual row bearing. I have an engine rebuild thread in show&tell, you can find pictures there if you want to compare.

LN can tell you what their records indicate the bearing is. I had a Single Row Pro (dual row replacement for a single row OEM bearing) installed in my car by my shop at 42k miles. It failed at 77k miles. When I contacted LN, Charles Navarro said the number on my install sticker indicated the bearing was made before the Single Row Pro was introduced and that it was a single row bearing. My shop receipt said the LN bearing was the dual row Single Row Pro, and the shop owner showed me the remnants of the failed bearing and said it was dual row, so I left it at that. The remnants went back to LN for analysis and I never bothered to try and find out from them whether my replacement bearing was in fact dual or single row.

I now have the IMS Solution. I would say it is as permanent as the engine's crank main bearings. Based on my experience of one failed IMSB upgrade, I would recommend periodic replacement of any splash/mist lubricated ball or roller bearing IMSB on some periodic basis.
