First off, the source of the debris must be found. If it isn't, and you just assume its the IMSB, and retrofit it, the chances of the replacement bearing failing are insanely high. Why? Because you have debris suspended in the life blood (oil) of the engine and the smaller and lighter it is, the easier it travels everywhere throughout the engine, and creates a loss of life as it travels through the engine.

What color is the debris? Do you have photos of it? Have you quantified that none of this has already made it past the filter by doing my "finger test? If metal laden oil has made it by the filter, the engine has been permanently damaged. The wonderful design of the stock oil filter housing allows this to occur.

Again, you must quantify where the wear is rooted and address is before any IMS Retrofit is applied, or any other intervention. I spend hours on this topic in my classes and it amazes me how many shops will just throw a part at the engine in hopes of fixing the root of the problem, when they really have no idea what the failure chain is really made up of. With this you must not guess, and you must cease vehicle operation until you have addressed where the debris is coming form, as well as ensuring what the collateral damages may be.
