No, I saw no reason for the wear. And I found no iron grit/filings in the pan either, so I'm assuming it happened a while ago and the grit was washed out with previous oil changes.All I can say Harry is that you have more determination than anyone I have met. To keep going and not let any of the curves stop you, that this one has thrown your way, is impressive to say the very least. Great job on the website and recording of the build. One question about the engine on that valve and valve retainer, did you find the reason for all that wear? Did you check out the oil flow to and through that lifter, pushrod, etc? There must be a reason it failed like that and before you run it is the time to find it. You could run the oil pump with a drill and see if you get any oil up to that rocker. If you don't check it before you run the engine, then for sure lift that rocker cover and have a look to see that its getting oil when you do your first start up. Better safe than sorry.
