My friend and I checked that via a dial guage on the piston top when the heads were off. When we moved the crank, the dial gauge indicated the piston moved. When we would turn the crank clockwise and then turn the crank very slowly counterclockwise, there was no delay indicated by the gauge, indicating to us the chain was not stretched.
Now I have the cover off and I see the chain has some play in it. So I am second guessing myself.
I will try your test, Robert, but I think I will find the chain is just fine. Thank you for the detailed write up.
Woa did I get that wrong!
We had a dial gauge on both the piston top AND a dial gauge on a camshaft lobe (see picture). When we moved the crankshaft clockwise, stopped, then slowly rotated the crankshaft counter clockwise, there was no delay in the gauge on the camshaft lobe providing a change in reading. That indicated to us the chain was in good shape.
