Maybe put an "IMS Guardian" from Flat6 in?
"The IMS Guardian™ is the first advanced warning system for imminent IMS failure (and eleven other modes of failure) that will automatically monitor the health of your engine.
Installing the IMS Guardian™ today prevents the guessing game of timing a more expensive IMS Retrofit, and the potential for an even more costly engine replacement.
At just $389.95 (MSRP), the IMS Guardian™ is inexpensive peace of mind. If the IMS Guardian™ alerts, shut down the engine immediately to prevent further damage and schedule a $995 (MSRP) IMS RetroFit to replace the compromised IMS bearing and save your engine. "
