A puzzling observation...
At 136,000 km I am going to change two valve shims to the next largest size as the valves are at the loose end.
What's puzzling\surprising is that even though the replacement valve shims are only available in 0.05 mm increments, the original shims are engraved to three decimal places, not two. My original exhaust valve shim is engraved 5.275X and my original inlet valve shim is engraved 5.475X.
I would have expected the original shims to be engraved to two decimal places, not three.
