    In 2015 and 2 months after i bought my 2005 carerra S, i did install the IMS solution, been trouble free and have operated flawlessy. Note: the original ims bearing was in mint condition, car had passed 65000 miles

    Have a 2005 Boxster with the larger M97 bearing, confirmed when clutch was changed. It’s a later 2005 model with a 2006 chassis. Not going to worry about it, trouble free so far after owning for 4 years doing 8000 miles a year.

      Zero, the base 2.7 has cast pistons which dont interfere with the bores. The 3.2 is the same, 3.4 onwards have the forged pistons. 3.4 is the safest of the trilogy (3.4, 3.6, 3.8) as less heat.
      3.4 is ok if you: Change oil often, install low temp thermostat, run premium fuel, use injector cleaner, don’t idle when cold and dont rev high until full warm

      Very safe bet the base 2.7, 2006 chassis cars will most likely have the larger IMS bearing. Chassis number has 06 in it.
      I have a 2008 RS60 Spyder now with the 3.4, and on reflection the base is just as much fun, you can exploit it more. I would have another one, and look for one with a high options list.

    This is the best and most comprehensive explanation I have seen on the IMS bearing and it's associated issues, thank you. I have had a 2006 2.7 Boxster without problems, a 2004 911 C4s which had an engine replaced at 49,000 miles, this car was worked hard. My 2003 Boxster 3.2s had the IMS bearing replaced as a precaution at 95000 miles.

    I am the previous owner of both an 1999 Carrera and a 2007 Carrera S. Never had a problem with either thank God. I was blissfully unaware of the IMS issue when I purchased my 99 Carrera but very aware with my 07 Carrera S. I kind of wish I still had that 07 but was scared off with the possibility of the even more robust bearing failing. I currently have a 2016 GT4 and again the engine has been completely reliable. I do all my own normal maintenance because I enjoy it. For some reason I am addicted to learning about these engines even though I know I will never again own an M96 or 97. I think I've watched all your videos. You do a great job in explaining the problem and solutions. I've applied much of what I have learned from your videos to how I maintain my Porsches. Well done and thanks.

    This is very informative, Jake. I've been educating myself on this topic among the other issues associated with the M97 since a family member is selling me his '07 C2S. While searching for additional info on the IMS bearing issue, I stumbled upon a BAT article and noticed this comment by "jr_racing" on 9/25/20 at 5:26 AM:
    "I have been building Porsche engines and racing them for over 40 years. The IMS bearing is a wear item that should be replaced approximately every 100k miles. The job isn’t particularly complicated but people should be wary of any shop that is charging over $2500 total for the replacement (including parts & labor). That indicates that they’re either overcharging you for the part or they’re not very experienced with the work. The “fancy” solutions are just as prone to failure as any others. We have had a few cars with The IMS Solution installed that have been found to have serious fretting issues on inspection. It’s a sad day for the owner when their $2000 “permanent” part gets swapped out for a more reliable roller bearing.
    Don’t forget to drive and enjoy, folks."
    I can forward you the link if you like, TH-cam deletes comments with links leaving the site. Since I am planning on getting the IMS Solution once I have the car and upon replacement of the clutch, can you please address this claim by this user? Thanks!

    • @RennvisionbyTheKnowledgeGruppe
      @RennvisionbyTheKnowledgeGruppe  2 ปีที่แล้ว

      The oil fed plain bearing that supports both ends of the intermediate shaft has been a proven durable design that Porsche used dating back to the 356 Carrera. Why they moved to a cheap ball bearing on the M96 Carrera and Boxster engines is ludicrous. It was a definitely a sacrifice to move to ball bearing to support one end of the IMS and cost them greatly with the class action lawsuit and countless engine replacements under warranty. Ironically, they continued use the oil fed plain bearings on the Mezger GT3 and GT2 engines. It took more than 10 years in R&D to bring the patented IMS Solution to the market and we believe it's the best "solution" for the IMS bearing problem. Therefore, the choice is yours which bearing you go with. We've already addressed the allegations this shop made regarding the LN Engineering IMS Solution on Rennlist 2 years ago.

      @@RennvisionbyTheKnowledgeGruppe Thanks for the response, Jake. I couldn't find the thread on RL, but I did find one where an owner asked about any failures on the IMS Solution (posted sometime in 2015). What I inferred is that maybe this shop is not a certified installer and did not do the pre-qualification requirements to install the IMS Solution? Is that correct?

    • @RennvisionbyTheKnowledgeGruppe
      @RennvisionbyTheKnowledgeGruppe  2 ปีที่แล้ว +2

      Hi. This is not Jake. Unfortunately, Jake Raby doesn't have time to monitor and respond to comments on TH-cam. I've passed along your message to him, but you're welcome to submit a support ticket at the FSI website if you need more information. You said you had a 2007 Carrera S, correct? Then IMS failure is not your big concern, it's cylinder bore scoring which plaques the S model 997 Carrera M97 engines. The IMS bearing, the 6305 that's on your car is very robust and we recommend living it alone unless you need to rebuild the engine and at that point we strongly recommend the IMS Solution from LN Engineering. I wish you all the best in your decision.

    You sir, are by far, the most informative person on this subject that I've seen online anywhere. I'm looking at a 2002 Porsche 911 4 cabriolet. The service record says that the RMS, clutch, flywheel, and other items were upgraded/replaced. I couldn't believe they didn't do the IMS so I called the service center in another state and they said the mechanic was standing there with an LN bearing ready to install it but noticed that the larger bearing was already there. They stated that it was an aftermarket bearing? I wasn't aware there were non OEM large after market bearings. They told me they think it was a roller bearing and said it looked great and left it since tearing the engine apart would probably cost a bunch. They also said the last shop purposely left a gasket out so the bearing would get lubricated.....Any thoughts on any of this would greatly be appreciated. Thank you.....btw, if it all goes well, I would upgrade to the IMS Solution. Great idea

    My car is a 99 tiptronic. Thought I did my homework and determined that it had the dual row IMS. No 'AT' in the serial number of the engine. Did discover that the engine was not original to the car and was replaced in Japan some years ago, but no other info could be found. The serial number corrsponded to a 99 C2, so seemed like the car had a used engine put in it. So I bought the IMS solution to replace the dual row. Got a call from the shop saying I had the larger non removable bearing ... now I have a beautiful IMS Solution I can't put in my car ... yay ... So that is my story.
    Didn't see anything in the video (or I missed it) but isn't the cover to the large bearing supposed to be removed? I seem to read that everywhere, so I had the shop do that to mine.
