Hi List!

I'm new to the whole Porsche experience and just bought a 1978 SC. I'm completely in love with this car. I can't believe I've waited so long...

Anyway, my question is simple...

What is the recomended mileage interval (typical) for changing the timing chain(s).

Aside: I also own a 1961 Mercedes and you can check the chain stretch by lining up the cam index marks and look at the crank timing marks to see how many degrees the chain has stretched. Once it gets over ~3-5 degrees, it's time to change.

I've searched the archives and can't find any procedure similar for the 911's.

Can someone please give me the "low down" on 911 timing chains?

Thanks!
Brad
