When the factory changed the IMS drive chains in the '01 model engines they also changed the metal tensioner contact pins to the plastic type...
Phil's engine had a metal wear pin because it was a 2000 model Boxster S, the only "S" with the metal contact pin and the old style IMS drive arrangement.
I probably won't have time to tear this core down for a while, but when I do the failure report with pics will be posted.
