Just replaced 3 of the Wilcox-Crittenden bronze tapered valves after 28 years. There was no corrosion, just some wear of the tapered plug and bore preventing a good seal, in turn causing a slow drip from them. They still all turned OK.
There are still 6 of the WC tapered valves working fine. These are the less used ones so have been less subject to wear of the bore.
We'll see how the Groco replacements fare.
If a little wear or wasp waisting was all the problem was, you should have been able to merely lap the cones with valve lapping compound to make them as good or better than new.
I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.
