Hi everyone. Tech question I could do with help please .

Tech question  help regarding Ims bearing. My boxster  2001 2.7 has covered 31000 mile immaculate car but having read everywhere I can re the Ims bearing have to say I am now more than slightly concerned! Questoon is should I be?  As I'm aware there is no way of checking this bearing apart from checking the oil for particles of metal. Should I be looking at changing the bearing or am I being paranoid? Whats the chances there could be an issue with it ? No oil leaks etc .  Would appreciate any help or info on the subject. The car is going for a major service soon  so is there anything they can check/ do to put my mind at rest?

There's a lot of talk about this in various Forums, which seem to over-inflate the issue and worry people perhaps unnecessarily. If you have any concerns there are checks that can be done before going to the effort/expense of changing the bearing. If the car is due for a service I would recommend a sample of oil is taken from the sump and put through an oil analysis spectrometer to check for PPM's of elemental metals. This will give the best early indication of wear/degradation in the engine internals (not just from the IMS bearing), and is a very useful 'industry standard' healthcheck. It is not expensive, and I have done this quite a few times for customers with low-to-high mileage M96/M97 engines at service time, and found them all to be in a very good state.
 
Regards,
 
Mike.

Hi.
For the Model you have it can suffer IMS bearing problems and Rear main oil seal leaks in the specific area there is no way you can check your Ims bearing only oil condition service time but obviously you can see the RMS  leaking some do mist slightly but as long as its not dripping don't worry about that.
You can have the Ims upgraded for peace of mind. It's one of those things some people never have a problem and others have if it goes without warning it can be very costly.
It's a decision only an owner can make do I don't I upgrade.
Why not give Steve Winter a call at Jaz a Porsche Specialist on the subject our resident mechanical expert.

Hope that helps

Your being Paranoid.
 
Failure rates are pretty low, and even lower in the 2.7 which is the car least likely to have the problem in terms of the cars that could get it.  You have a low mileage car that is probably being used occasionally and probably being well looked after and not being thrashed about so it is unlikely to show. 
Get the oil analysis done at the next service for your piece of mind and if you ever get to doing the  clutch they can check it then.
 
I see the "ŔMS mentioned again" they will occasionally sweat or drop a spot of oil after an enthaustic drive or a very hot drive until it starts dropping oil regularily after most drives then you should leave alone unless you like wasting a £1000+ replacing.

One thing not mentioned above is that your 2001 car is possibly a transition year where it changes from dual race to single race.  If you have a dual race I really wouldn’t worry about it.  If you have a single race, then ... then it is still very unlikely to fail (I have about 600 customers and I’m not getting regular phone calls about failed ims!).  If you post your vin, someone will kindly tell you which you have.
I am sceptical about the oil analysis as it assumes degradation is slow.  I don’t believe it is, I think the bearing (if it does fail - see above!) collapses in a short time frame.   
Kind Regards Lee

Many thanks for all of your reply really appreciate the input. As Lee states I'm not sure if the bearing is a single or dual race bearing. Anyone enlighten me on this please.? VIN number Wpozz98z1u601725. Booked in for a major service so I will get the oil checked at least.
once again cheers guys.

No problem. Looks like an early 2001 build, and not on the list of VINs declared as affected on the class action lawsuit filed against them in the US (which covered RoW cars as well as US spec), so most likely the early dual-race version. Either way, drive it and enjoy it!

For a 2.7 M96.22 to have a dual race IMS, the Engine number has to be <65112852.
For a 3.2 M96.21 this is <67111238.
