Pulled the idler out
aligned the dots again
got the idler started
then slide the cover on, then off
Checked the clearance to the block +.010
Rolled it over a few times to check the dots
Then mounted the indicator

After that sequence the idler (right) side had obvious movement.
The quick measurement although at a slight angle seems to give me .008.

I was surprised how far back the cover pushed the idler back and how incredibly difficult it is to get the idler gear installed.

It rolls over very nicely. I may try to put the rockers on tomorrow and see if that changes anything.
