It looks like my marks do line up but I apparently made them when the engine was NOT at TDC.

I'm not sure how or why that happened but that appears to be the case.

As long as I put the crank where my marks on the chain and cam gear as well as the marks I made on the cam relative to the mark on the front bearing cap line up should I be OK?

I'm increasingly convinced it would be very difficult for the timing chain to actually slip.

I think I'll proceed as though my assumptions are correct....wish me luck...
