Wayne, I just read the article on the Guardian, and it is a metals particulate sensor that collects ferrous metal using magnets and then triggers when the accumulation level meets a predetermined level. Common military aircraft stuff, which is Jake’s background.

I have to agree with the comment in the article where it notes that by the time you see the cam deviation values go out of wack, the engine is already full of metal. We have only “caught” a couple of M96/97 engines with the cam deviation technique, and they were full of metal crud in the sump and oil filter. I have heard similar stories from others than have observed the same thing. Jake’s idea is to catch the metal build up quickly and early in real time, before the engines have so much metal running around in them that the IMS bearing becomes the least of your worries…………..
