Unfortunate that it failed, but that is a single row, not dual row. Seen it before. If I recall from the original poster's email to us, the original work order for this job did show a single row bearing, however the engine was certainly not qualified as they didn't even change the oil and filter (and obviously the pan was not removed for inspection). Obviously not registered either.

The previous owner also didn't used DT40 oil not did they really understand what was being done to the car. The fact that the wrong bearing is on the work order made me second guess if the bearing had even been done. It had... just not well. LN Engineering have been extraordinarily helpful especially since I have another engine that is not going to get the "IMS Solution". The RMS of the replacement engine is walking out and so we need to access the bell housing area again anyway. Thanks again Charles et al!

Not 996 but I had the first gen 2006 997C2S. Sold it at 86,000 miles with zero IMS issues. That's a much bigger failure rate than Porsche claims.

Glad I can finally cast my vote. IMS replaced with Single Row Pro on my 120k mi 2002 Targa. No issues with original bearing...was still serviceable. Oil stuck in the IMS shaft behind the bearing was gross.

Replaced my stock IMS bearing at 90k miles, bearing was in excellent condition with no play. I have a 2002 Targa, so I believe it’s a single row.
Cheers,

2003 996 bearing failed in 2005 at 20,000 miles - replaced by Porsche under warranty (entire new engine from Germany installed).
Still have the car, now at 70,000 miles. (I am the original owner.)

Just got a 2002 996, with 98,000 miles, engine was replace by Porsche at 42,000 miles, so "new" engine has been on the car for 56,000 with no issue. I am dropping the pan this weekend and doing an oil change. Also upgrading to the LN Spin on filter.

I replaced the stock single row IMSB on my 2004 C2 with 90k. Original bearing looked good but there was a slight leak at the bearing cover. Hardest part of the job is reinstalling the 6speed transmission. Drilling out a snapped pressure plate bolt took some extra time...

2004 C2 with low miles. Replaced bearing last year with Solution for Peace of Mind. Bearing in the car was fine. Done by Solution certified installer here in Maine who I would highly recommend.

148k miles with no evidence of IMS replacement. bought at 142k (cant be sure it wasn't done already). Keeping an eye on it! So far bore score is more worrisome, because oil consumption (this was at >130mph on a german autobahn though)...

Unfortunately it seems to be the low mileage cars that always grenade. If the oil was changed every 5000 miles, and the car only has 33,000 miles, then that means it’s only had 6 or so oil changes over 20 years. That’s sorta nuts. Old oil eats the IMS bearing seals up.
I’d recommend that you go to Mayo’s instead of Zims. No offense to Zims, but Mayos is a certified installer for the IMS Solution, which is no small feat. I’d also recommend that you consider doing the Solution instead of a ceramic replacement if you plan to keep the car for 5 or more years.
