Rear Main Seal (RMS) for MY97-08 M96/M97
$41.36
When servicing your intermediate shaft (IMS) bearing, it’s important to also replace your rear main seal (RMS). The part number has been superseded to an updated PTFE seal that is proven to resolve most leaks. We only recommend using the Genuine Porsche seal – stay away from all other replacement rear main seals. Products that claim to add more support to the crankshaft by adding another “bearing” falsely claim the weight of the dual mass flywheel is the reason for rear main seal leaks, when in fact engines that have been found to have chronic RMS leaks do in fact leaks because they were improperly machined from the factory, requiring engine replacement to correct this condition. This can be checked for using Porsche Tool 9699/1 or with precision measuring tools to ensure there is no more than 0.3mm of runout between the crankshaft and the housing bore into which the RMS is installed. It is also critical that the proper tools are used to install the PTFE seal, as if it is improperly handled or installed, it will fail to seal and will require replacement to correct any leaks as a result of misalignment or if installed to the incorrect depth.
