yangin Posted 4October, 2017 Author Report Share Posted 4October, 2017 Thanks for the advice. I think I will be replacing bearings when RMS is replaced.Sounds like I need to also do some research on Variocam/solenoids... Link to comment Share on other sites More sharing options...

Ok, so it's clear now the 01's to 05's are the ticking timebombs, tick tick tick tick, get those bearings done just in case fellas.

Troubleshooter Posted 19December, 2017 Report Share Posted 19December, 2017 No need to -- though the donk had the bearing changed prior to purchase while the clutch was done. I do sleep well at night. Link to comment Share on other sites More sharing options...
iluvbrownale Posted 22December, 2017 Report Share Posted 22December, 2017 There's plenty of conjecture about failure rates of IMS but is there any experience of the fixes going bang too? Or can it be guaranteed that an IMS replacement means you're safe? Link to comment Share on other sites More sharing options...

Well actually, quite an interesting story over on rennlist, an Australian on there went to replace the IMS with the IMS solution and the new one didn't fit. He had to rebuild the engine but turns out it was actually previously rebuilt with upgraded Nikkies cylinder liners and an upgraded IMS, WIN! Well kind of... https://rennlist.com/forums/996-forum/1039071-a-journey-into-the-unknown.html Strange the previous owner didn't keep receipts of such extensive repairs Link to comment Share on other sites More sharing options...

Or can it be guaranteed that an IMS replacement means you're safe? the IMS solution is the best type of bearing, from an engineering point of view. It's the same type of bearing as Porsche used at the other (non troublesome) end of the intermediary shaft. all wear components will eventually fail. LN offer a 5 year warranty on the part. I haven't seen anyone reporting failures from it yet on the US forums. Link to comment Share on other sites More sharing options...

Zelrik911 Posted 22December, 2017 Report Share Posted 22December, 2017 Hmmm - interesting read on Rennlist. My suspicion is that the motor's primary problem was scored bores &/or DChunk then probably seized up - putting pressure on the IMS chains & spocket. If the original rebuilder told the then owner that the motor was still somewhat ''delicate' after the fix, he would have onsold the car ASAP without talking about the motor. BUT - as part of a purchase PPI, wouldnt the ODB scanning software detect a timing out situation or cam mismatch?? Link to comment Share on other sites More sharing options...
Mike D'Silva Posted 25December, 2017 Report Share Posted 25December, 2017 The interesting part about part about the IMS solution going back to a plain bearing, is that all the plain bearings in aircooled motors on the intermediate shaft, don't last that long either.. I don't think they disintegrate, but when you pull a motor apart, it is common to replace them every time since they are usually already worn through the bearing surface.

Pokiou Posted 26December, 2017 Report Share Posted 26December, 2017 There is NO such thing as a IMS solution. There is no solution for i, if there was Porsche would of done it like they did in the Turbo and GT series motors. All those other LN engineering style and other branded IMS are just gimmicks in my opinion that need to be replaced with most clutch changes. So its not really a solution. At the end of the day, most of the cars having IMS issues are ones that sit around for months at a time and never get "DRIVEN". It's counter productive to a way a bearing is supposed to work.

I think you're confusing the IMS solution with the IMS retrofit. The solution is a lifetime replacement the retrofit has a service life and does indeed need to be replaced (usually whilst changing a clutch) to save on labour costs. Not being driven and IMS failure dont necessarily correlate from the cases I've read. Link to comment Share on other sites More sharing options...

Personally, no but the manufacturer does. I've got the IMS Pro retrofit in my car. When the service interval is up I'll be having the solution installed which is a lift time solution. It's a plain oil fed bearing rather than a splash lubricated ceramic hybrid ball bearing. Both are far superior im every way to the original and its an insurance policy against bearing failure.

Pokiou Posted 27December, 2017 Report Share Posted 27December, 2017 Don't get me wrong, i'm not trying to be a d1ck or anything but i too would love a life time solution but the IMS Solution is only 5 years warranty and even less for the retrofit. IMS Solution LLC warrants that parts purchased from an authorized IMS Solution dealer or distributor, that were installed by a qualified installer and that were installed in compliance with, and precisely following, all guidelines and procedures, to include registration, set forth in the product installation guide, are free from defects in materials and workmanship for five (5) years/unlimited miles from the date of part installation for the single or dual row IMS Solution (106-08.20 & 106-08.40). The Single Row Pro IMS Retrofit is covered for two (2) years/24,000 miles from the date of part installation. Link to comment Share on other sites More sharing options...

I would say so as there is not a better engineering response to this issue and would be confident that this bearing would then outlast the rest of the engine. I agree with Dan, if you suffer any sort of IMS bearing anxiety, just stump up extra for the "Solution" so you're free to worry about something else!

ANF Posted 27December, 2017 Report Share Posted 27December, 2017 A different perspective.... With the 996 now approaching 20 years old (which for car companies is way past a "lifetime" for a model) and with a failure rate of under 5% (and if you listen to Porsche about 1 to 2%), the surviving original bearings are a lifetime one!

That said the solution is "designed" to be a lifetime solution as it has no service interval. The retrofit is "designed" with a service interval. IMO warranty is not the discussion point, design is. Either way they are both upgraded parts which are superior to the original. However whether one chooses to replace their bearing or not is entirely up to them. For me it's an insurance policy and the retrofit pro was the entry level policy which I was comfortable taking out (or putting in!?). Link to comment Share on other sites More sharing options...
Ten Degrees Posted 2January, 2018 Report Share Posted 2January, 2018 If you take your 997 to a Porsche Centre with concerns about the IMS, what do they replace it with? Do they use the last version of the OEM bearing? Link to comment Share on other sites More sharing options...

The M96 you can replace the bearing by dropping the gearbox if you have the 3.8 an entire engine tear down is required to replace the bearing. In an interesting turn of events Porsche have a part number for a replacement M96 IMS bearing. Link to comment Share on other sites More sharing options...
