There are a few simple things that can be done next time you’re having your Porsche vehicle serviced to give you some peace of mind before you take the plunge and have an IMS Retrofit™ kit installed on your car.
When doing an oil change, check the filter for any debris whatsoever. Same with the magnetic drain plug. Any sparkly metallic (magnetic) debris means you need to stop driving your car and plan to install an IMS Retrofit™. Even if there is only one piece, it’s a good bet your bearing is failing. It is advised that you pull the oil sump plate to check the sump for additional debris. Here is what IMS bearing debris looks like in the filter once there has been an IMS bearing failure.
Timing is everything. If you wait too long, a catastrophic failure may preclude the ability to replace your IMS bearing with an IMS Retrofit™ kit. Remember, often there is little warning of an impending IMS failure. Bare minimum, you need add a magnetic drain plug and our full-flow filter adapter to ensure that 100% of the oil is filtered and contaminants cannot reenter the engine. This makes for easy inspection for IMS debris at time of performing an oil change.
Please note that used oil analysis, however very useful to detect problems like cylinder bore scoring or rod/main bearing wear, cannot be used to check for the health of the IMS bearing as the debris generated by the IMS bearing is larger than what used oil analysis can identify (without separate particle size and count testing).
