My tea20 project has been on the back burner for about ten years now, but I might finally have some time to revisit her. I think we've had this conversation before, but my memory is a bit foggy. I obtained a replacement block. Had it cleaned up and flushed out. I slid the camshaft from the original block into the new to me one. It fit no problem, but it got me thinking at the time, with no bearings, what are the chances that the 2 blocks wore the same. Short of taking it to the machine shop and getting it fitted with a set of cam bearings, what clearance between the cam and block are acceptable. I could mic the block and the cam, but how much is too much? Has anyone ever had a set of bearings made? I remember thinking at the time that this is the first engine I have ever seen without cam bearings.
