There must be many others like me, who have arthritic wrists which no longer articulate well.
Therefore checking gap when hot is a definite no no.
Checking gap accurately with manifold on is also an impracticable no no.
However if I can discern a discernible movement by feel on the tappet to be measured I am content.
This is not ideal or recommended , but better than not knowing about a tight tappet clearance.
4, 6, 8 thou measurement with the engine in the car would be in my dreams!
