<div style="color:black;font: 10pt arial;"><span style="font-size: 10pt; background-color: transparent;">Had the rocker shaft off my TR4A recently and found several valve stem tips pitted and peened over. </span><br>
<div>
<div>Metal was displaced so a finger nail could feel it. Would you call it Galling? <span></span><span style="font-size: 10pt; background-color: transparent;">Head was done about 35K miles ago.</span></div>
<div><br>
</div>
<div>I've never seen this before. <span style="font-size: 10pt; background-color: transparent;">Stock Crane camshaft, valve springs and tubular pushrods. Valvoline VR-1 20W-50 </span>oil.</div>
<div><br>
</div>
<div>The rocker arm pads have been ground at what was supposed to be the correct radius. Don't know how to verify that.</div>
<div><br>
</div>
<div><span style="font-size: 10pt; background-color: transparent;">Has anyone experienced this? How does it happen? My inclination is to replace the all valves and rockers.</span><br>
</div>
<div><span style="font-size: 10pt; background-color: transparent;"><br>
</span></div>
<div><span style="font-size: 10pt; background-color: transparent;">Thanks </span>for any insight!</div>
