Ok, removed the cam tower. It is neat how easy it is to remove the Loctite when it is new. A good use for moonshine maybe. Pics show how I did the test. I could not get a .015mm under the ruler. I put the cam in the tower and it still has a little resistance at one spot. I pulled the cam out and tested each journal (I guess that is what you call it) and found the #2 to have drag. So, to the hone for some gentle polishing.
