A few weeks ago, I pulled the head off my 250 in order to have a machine shop drill out a broken intake manifold stud. Yesterday I was going to put the head back on, but before doing so, thought I would pull the tappets out to inspect them. Found one that was pitted. Cam lobe is fine. Wanted to post a picture but I have no website.
My questions now are: Do I need to re-cut the tubular push-rod to fit the new tappet I will be getting? I'm thinking I can make up the slight difference by setting valve lash. Secondly, how do I handle the break in of tappet? Or, are break-in procedures primarily for the cam, which is fine with over 3000 miles on it?
