Worth it to 'check' IMS bearing during clutch? Clutch recommendations?

Sounds like rocket science. It`s literally pulling out a bearing from a bore and pressing another one in.

Again, at the time, Porsche denied it was even possible. Jake and Charles developed how the engine has to be configured (locked at TDC, tensioners removed, cams locked) and the actual tools to do it. While I’ll may not seem like “rocket science” to you, without the procedure and tooling, Porsche was correct.

Of course Porsche would say it`s impossible, they want you to buy a new engine or a new IMS and rebuild it using genuine parts from Porsche. Also, Porsche would never admit that a working IMSB has to be replaced to a new one in a preventive manner. And if it fails, the engine has to be disassembled anyway, pulling it out is not an option.

The need for locking the cams and the crank when messing with timing is obvious. When I need a tool like that, I make some measurements, make a drawing, walk to a machinist with a lathe and have it done. But the IMSB can be extracted using simple bearing pullers off the shelf. So this developing the right tools and right procedure taking a lot of time seems a little bit exaggarated to me.
