OP Have you read this topic? http://911uk.com/viewtopic.php?t=108257

If not make a brew and have a read.

I have recently bought a 996 and read the internet and scared myself silly. I read that topic and spoke to a few people I feel I can trust on the matter and stopped being scared.

I had the clutch, RMS, LTT, water pump, coils etc done before I picked up my car and had the IMS inspected. It was found to be fine. While they were looking they popped the seal out. I really believe that is the way forward and I am happy to drive my car for the next 5 years or what will probably be 30,000 miles. In 5 years time my car will then have ticked over 100,000 miles and the engine will most likely need a rebuild if I want to continue using it to it's full potential. Bearings etc will be worn like any other engine.

At that time my Porsche fund will hopefully have built up enough to fund a Hartech rebuild and I will be ready for another 100,000 fun filled miles. Yes it will probably cost 12-15k and represent at least half the cars value even if prices rise as they have been doing. If they do or don't I will have a fresh engine in a brilliant car that still cost me a fraction of anything that offers similar performance and satisfaction.

Until then I will use quality oil, change it regularly and warm the engine before I spank it. Oh and fix the lumbar support.
 
...I am inclined not to rely on statistics that I believe were used in some American court case or other many years ago to reinforce claims that ims bearing failures are rare and rely more on the apparent and practical realities...hartechs business pivots around failures of this engine and the 3 indies that I spoke with prior to buying mine plus the one now rebuilding my engine (which is third in the queue of ims failure) all were rebuilding broken ims related failures at significant expense and inconvenience!

It is singularly and peculiarly unhelpful to repeatedly regurgitate those meaningless statistics as it is no help at all to potential purchasers with related questions...It might make you feel better Alex but aside from that adds little of value?

I couldn't care less what others choose to do but I would ,if asked, only ever advise that if one is concerned one should take action sooner rather than later...the last thing I would advise is not to worry!
 
If anyone wants their IMS replacing, I will gladly take £1000 off you for doing it and it will come with a cast iron Guarantee that, if in your ownership, the bearing fails, I will buy you a brand new 991.

No gearboxes will be removed during this process.....but I will supply one of these:

my car i a 99 3.4 which has the dual row bearing now clocking on 100k the rms is leaking so in the winter i am thinking of changing it, if the ims looks dodgy what could i replace it with? as the dual bearings are no longer available.
 
If you want to change your IMSB, I would make sure it is carried out by someone experienced in this work.

I'm not recommending them through experience, but the people below seem to have a good reputation on other forums for this work.

Google Porsche IMS bearing specialists and a list of respected Indie appear. Other forums could be useful. Try PistonHeads or other Porsche forums for recommendations. Not many recommendations for bearing replacements appear on here.

I'm telling you now - it'll be fine. Just ping the outer seal off the bearing so it spends the rest of its days in fresh engine oil.

Ps. It might be your ims cover plate leaking and not rms. You won't know till you're in there.........and I wouldn't even bother sorting tour leak unless you're having a new clutch fit.
 
Just warm it up carefully and warm it down carefully and in between cane the arse off it and change the oil regularly.Jobs a good 'un :thumbs:

Mine is an early 2001 3.4 but I don't know whether it has a single or dual roller bearing. I was wondering if it's taken out and it's found to be perfect is it advisable to get a new one or stick the old one back in? I guess having gone that far it's best to stick a new one in as the bearing itself isn't that expensive or so I've been lead to believe. I'm easily lead btw :wink:
 
You will have the dual row. You don't need to remove it to check it. Pulling the bearing out in situ can do damage to other engine components like chain guides. Have it checked, remove the outer seal and then leave well alone.
 
I looked at mine recently, 130k 3.4 MY99

I was replacing the clutch and flywheel (on my back on drive in the snow).

Locked the cams with a homemade tool and whipped the tensioners out for new seals.

Whilst there I took the IMS bearing cover off and inspected the bearing.

Mine felt like new, no roughness, no play, just buttery smoothness. I removed the bearing seal and old oil came out, I left it off as Alex says it will now get effectively fed new oil all the time.

Used loads of blue sealant on the cover going back and popped in the latest RMS whilst I was there.

Thanks. As I'm not a mechanical genius can this be done with the engine in situ and without removing the clutch assembly?
