Re: What causes valves to stick?
Getting coolant into combustion chamber with cause a sticky valve. That's exactly what happened to my '72. It would have one stick after sitting more than a week or so when I first started it till warm up. Never smoked, no noticeable coolant loss, no milkshake on oil cap. It was this way for a few years or more. Ran great, plenty of power, oil looked fine with each annual/semi-annual oil change. It was burning what little leaked in
Went to pull headers to change front brake hoses. One plug broke off. Went to remove the base and it wrung off. Pulled the head and one cyl didn't look too good. Had magnafluxed and a hairline was found.
