Point of no return
Took the camshafts out so I could check the thickness of the shims. They look a lot like steel Altoids, only a bit smaller, and crunchier. Each shim is supposed to have a two-digit number which tells you what the part number is and thus how thick it is. About half of them did not have numbers or were illegible. The number looks like it's printed on with a dot-matrix printer; I don't think it's laser-etched. Fortunately, I have some vernier calipers and was able to measure their thickness. I'm not sure this is very accurate, since I can only measure to 0.1 mm, and the shims come in 0.05 mm increments. I think I'm going to have to get a micrometer to be sure. However, in all cases, the clearance is too small, and I think if I end up getting 0.05 mm too big, I'll still be within tolerances. I just know these little bastards are not going to be cheap, and I need five of them.
