Have you replaced your IMS bearing?
#16
I think changing the IMS out is a good idea, especially if you did your homework and budgeted accordingly. My "guru" will change mine out, and the clutch (don't need it, but if you got the engine out, why not) for two grand. I will sleep much better at night and never worry again the rest of my life (65 years old)….

After spending way too many hours researching Boxsters and IMS issues online, I picked up a clean 2002 Boxster last week. It has 41,000 miles and runs great (I've test driven maybe 5 other Boxsters before picking this one) and I already have appointment scheduled to replace IMS with LN Engineering bearing. Debating spending the money now, but gives me piece of mind and removes worry of the issue. I'll also be daily driving this Boxster, so part of the decision to replace. If I decide to sell it down the road, also a selling feature.

So far, of everyone posting in this thread that has done the replacement (of whatever version) all have said their bearings were “pristine”. Mileage doesn’t seem to matter. I’ll do mine when I do my clutch. Currently, everything is fine and it is hard to justify spending the $$$ up front when to do the whole thing right should be IMS, Clutch, Flywheel, RMS. Otherwise it is almost pointless to take the trans out to just do one, or a lessor combo at the end of the day. I’m not big on replacing parts that don’t need it. I suppose I’m playing the odds, but they are stacked WAY in my favor. If my engine goes boom, then it gives me an excuse to do a 3.6! :-)

That assumes it WILL fail. That's just not the case. Sure, there is a slight gamble part of it, but let's be clear, just because a bearing was replaced, doesn't mean the new one is fail safe. If you pull a pristine bearing, then install a pristine bearing, well... there really hasn't been any real net gain, short of age. I still think, in the end, to do as part of maintenance "while you are there" with a clutch and RMS all along monitoring oil etc. is a reasonable approach. YMMV...

Ocean Front Property in Arizona
Like most of us in this world, we've all seen loads of BS over time, but the IMS failure in the M96/M97 Porsches is not an assumption, myth, fish story, or ol' wives tale. It's a fact. If you think it's not, then I have plenty of ocean front property to sell you out in Arizona. There was a time that I thought IMS bearing failure was a big joke. I mean really, how can Porsche - one of the greatest sports car companies - get it so wrong??? Surely, this is just a snake oil scam conjured up by those seeking to benefit from people's fears. But after seeing several of my 996 friends have locked up motors from IMS failure, I began to think otherwise. I know you don't know me from Adam's house cat, but it doesn't take long in Google or Rennlist searching IMS failure to see this is not some sick made up scam. I'm sure you've heard stories of shops that claim they've never seen an failed IMS bearing. I can give you a list of shops that see nothing but IMS failures. The certified IMS Solution shop I dealt with had stacks of intermediate shafts where the bearings had failed and the owner told me those are the ones that they've kept for demonstration purposes. Most of the ones they had throw in the metal recycle bin. The shafts were bent and looked just like the images on the PCA website. The OEM bearings had disintegrated inside the shaft leaving behind trails of worn twisted scarred metal.
These are preventive measures. That's why I say it's better to be proactive than reactive when it comes to the IMS problem. Replacing the IMS is a heck of a lot cheaper than replacing the motor. Get my drift?
Yes, there is! You've gained more longevity out of the motor. Think about it. If you ignore swapping out the bearing, guess what you've gained? ANSWER = Roller!
That's not totally unreasonable. But again, it's always wise to have it done asap. If you get lots of metal in the filter, then it's too late. And... If you don't won't to worry about "miles" on the bearing, then purchase the IMS Solution.
Cheers!

actually, no. with the cost of a used 2.5L engine being approximately the same as the cost of R/R tranny/IMSB/clutch/RMS, it really doesn't make a whole lot of sense IMHO to proactively change them out unless you already need a clutch or leaking from the RMS. My RMS is leaking now but I'll put it off and enjoy my new $3000 Boxster
Buying another low cost Boxster is not always the best idea either because you're buying a car than in many cases will have the same problems that need to be addressed. Follow me? I'd rather invest in a car that I've cared for instead of hoping to buy another with lots of mysteries. Just my opinion... I guess I foot dance this rollin' log alone. ha!

Anyway, I agree that it's not wise to replace parts that aren't a problem, but that's not the case with these bearings. How many miles on your car? Is it the original bearing? What model?
There are plenty of other issues on these older cars that need attention. When the time comes I'll do it. And I'll probably do the single to double conversion with a recommended interval. To do 'The Solution' the engine needs to be "cleared", so to speak, to be approved for the addition, and I'm pretty sure it MUST be installed by an approved technician for the warranty. It's a pretty strict process from what I gather to get a motor approved. Either way, spend your money how you wish, and I will do the same. Hopefully, your chain ramps aren't disintegrating, your variocam o-rings are nice and healthy, your heads aren't cracked, or any number of things that can kill these engines.
I have succeeded. hahaha

Actually, yes. I'm speaking specifically of the IMS bearing install, not the clutch kit, RMS, etc. Many shops out there will install a LN retrofit on these cars for around $2,000 - $3000. I understand it makes sense to replace other wear items "while you're in there", but still if you're just doing the bearing, it can be done cheaper than most expect. I know many DIY guys are doing it for well under a $1K. They are buying LN RetroFit bearings at a discount from the LN eBay store and renting the extraction/install tools.

you seem pretty adamant that everyone should feel the same way you do. but in the end, there are more important things in life than worrying about a bearing. so it's a pointless argument

I follow you completely, I just have a different viewpoint than you. I like to buy cheap project cars and fix them up; I do all the work myself, and will probably do the IMS myself too.

Why not query the bearing kit suppliers and get some reasonable figures, subtract that from production figures from Porsche and get some sensible statistics, I know LN will give you figures, they have me in the past. My last recollection was over 30k LNs of varying configurations.
