"IP indicator blade is visible and centered, install the locking tool" - Is this done by looking through where the plug was removed in step #9? If so, is it doable with the IP still in the car (having a hard time imagine getting my head down there...)?

"Once out of the engine you can disassemble the timing device itself and swap your good rotating cam into place for the damaged one. Then you can reassemble everything in the reverse order lining up the paint markings on the timing device sprocket and the timing device thereby avoiding any timing alteration issue." Looking at the timing device, it doesn't appear it is easily dissembled. The entire timing device to include the cam/lobe appears to be pressed fit (no bolted connections, etc.). How would I go about swapping the whole timing device?
