BY GOLLY - I THINK I GOT IT!

I have finally got it - measured it several times (following the excellent advice from this forum) and I am measuring 15 degrees stretch on the crankshaft. If you compare that to specs for my engine - 617.912, camshaft code 08 (13.5 degrees of stretch after 20,000k) - I am only showing 1.5 degrees of chain stretch!

Measuring it the other way - lining up cam marks (which I have done numerous times) - I showed anywhere from 3-5.5 degrees of stretch.

I suppose I could be off a little with the 2mm method - only used 1 inch travel dial gauge, so it wasn't EXACTLY perpendicular - but I think I was pretty close. I am assuming I should go with the 2mm lift results...

If so, I think I will leave the chain alone...

Again, thanks for the help!
