John,
I have the mechanical tensioners from Stromski installed. I've been using these tensioners for cam timing set up and never had any problem in the previous dozen engine rebuilds. They are still installed at the moment. And will be removed when I installed the Carrera hydraulic chain tensioners.
Could I remove the valve springs with the cam tower installed so I could test if the valves are sticking? Do you know the ID of this Porsche tool? BTW, this was the 3rd. time the cam timing was adjusted and set. The first 2 times there were no slapping or ticking noises when you rotate the crankshaft. This time after the 3rd. time to set the cam timing, you could hear the noise every 120 deg. travel of the crankshaft pulley.
I am trying to think very hard what I did differently this time compared to the previous cam timing jobs. I am listening to suggestions and comments from everyone. What would you do if you were in my shoes to resolve this problem? Thanks.
Tony
