Porsche IMS Bearing Upgrades

The internet is full of horror stories of catastrophic Porsche engine failures due to IMS bearings breaking up. The reality is it’s not an everyday occurrence but there is a risk with Boxster 986, 911 996 and early 987 models. The solution is to fit an upgraded IMS bearing for peace of mind.

What are the symptoms of IMS bearing failure:

The symptoms of an IMS bearing failure are not always obvious and therefore it could be too late before you realise there is a problem, and by this point it can be a very costly engine repair.

There are some obvious signs that Parr would check for when servicing your Porsche which do indicate IMS bearing issues. Parr would certainly not advise to leave the standard Porsche IMS bearing until an indication of failure was evident. Parr have been using an aftermarket ceramic bearing for many years now. Parr would always recommend to upgrade the bearing to prevent possible failure. Its is also a selling feature of the car if the IMS bearing has been upgraded a its such a well-known potential problem area.
