Nice bit of information, would have made my decision much easier to have just counted the fins. I am taking a break today and doing some more reading, trying to stay ahead of the hands on. Reading the post; Making A Piston Clip Tool (Guerilla Method) It seem that porsche require a special tool for every item installed. As Wayne suggested, I used the end of a spark plug to remove the cam gear pin. I made my on tool 9191 to hold the cam sprocket, and my home-made smoke machine identified a vacuum leak in the throttle body linkage passage.
I am not familiar with the guerrilla inventive association, but mcguyer tool making sure apply when trying to avoid the cost of some of these special tools..
But as said earlier, necessity is the mother of invention. Someone will soon start a post asking to show all of the home-made tools made. a fitting tribute to Mcguyer.
Not sure if the host would appreciate that though. Competitive alternatives??
