THE FIRST. THE ORIGINAL.
The IMS Retrofit is a registered trademark of LN Engineering LLC and the original ceramic hybrid ball-bearing replacement for the M96/M97 engine - the only one trusted by hundreds of independent mechanics and used by dealerships worldwide.
The IMS Upgrade for MY06-08 utilizes an adapter bushing that converts the larger bearing journal to accept the Single Row Pro IMS Retrofit (included) so that after engine re-assembly the IMS bearing can be serviced without future engine disassembly.
If you have a 2006-2008 Boxster, Cayman, or 911, don't worry about your IMS bearing. Keep reading below as to why and what you can do about it.
WHAT CAN I DO ABOUT MY NON-SERVICEABLE MY06-08 IMS BEARING?
The incidence of failure with a 2006-2008 M96 or M97 Engine as found in the Boxster, Cayman, and 911 that have the larger (but non-serviceable) IMS is highly unlikely. Best estimate is about a 1% failure rate.
The IMS can be changed and updated to the IMS Upgrade with a Single Row Pro or the IMS Solution (which is a permanent fix), but the cost on average is $15-20k for a full rebuild, including addressing known issues while the engine is apart. The upside is that you can increase the displacement up to 4.0 liters with our Nickies cylinders.
However, there is some preventative maintenance you can do. When you have your clutch replaced, it's best to have the grease seal removed off the original bearing to allow engine oil to better lubricate it. At that time, you can reseal the IMS flange and have the rear main seal replaced as well.
There is a black plastic seal on the front of the bearing - you would use a dental pick or something similar to pop the seal out of it's groove. Just be sure not to loose it in the engine when you do remove it. We don't have a how-to for this, but I found a short video on YouTube that shows seal removal on a ball bearing.
The larger bearing found in MY06-08 engines has the same load capacity as the early dual row, which have proven to be the most reliable of the factory bearings. I wouldn't worry too much about it after you pull the grease seal. There is no need for a direct oil feed or forced oiling for the factory ims bearing as the bearing will be submerged in engine oil once you have the grease seal removed.
We would additionally recommend changing your oil every 6 months or 5,000 miles and use a quality oil like Driven DT-40 along with installation of one of our spin on oil filter adapters and magnetic drain plug.
