Major Problem Advice Needed

I don't want to pile on, but in this example it is your finger that swells in the heat (making ring feel tighter) and your finger that contracts in the cold (making ring feel looser).

No worries about piling on. Sucks being wrong so publicly, but I have learned something today, and I appreciate you explaining how the example I gave doesn't apply.

Thanks gents.

When my former father in law does a valve job on a Harley he'd heat the head and freeze the valve seats before he'd install them.

And press fit piston pins -
chill the pins, and heat the connecting rod, push together and when they both get back to ambient it is a press fit.
