I=92d suspect the valves and not replace the rockers unless they show a wea=
r pattern. The softer of the two metal surfaces would deform.
Just my $0.20 ($0.02 after inflation)

Subject: [TR] Valve Stem Wear
Had the rocker shaft off my TR4A recently and found several valve stem tips=
pitted and peened over.
Metal was displaced so a finger nail could feel it. Would you call it Gall=
ing? Head was done about 35K miles ago.
I've never seen this before. Stock Crane camshaft, valve springs and tubula=
r pushrods. Valvoline VR-1 20W-50 oil.
The rocker arm pads have been ground at what was supposed to be the correct=
radius. Don't know how to verify that.
Has anyone experienced this? How does it happen? My inclination is to rep=
lace the all valves and rockers.
Thanks for any insight!
