[QUOTE="RaYzerman19, post: 1294730, member: 18388"] Out of all this comes some positive learning from a negative experience........ one knows what to do next time or on your first valve check/shim change. While checking your valves, you're spinning the engine, taking your readings, or perhaps taking a second set of readings. If you are going to change shims, it is best to spin your engine to leave #1 at TDC, crank and cam timing marks aligned, cam chain tie-wrapped at crank and at sprockets, loosen CCT, proceed with shim changes. With the cams back in, it is then easy to verify the timing marks are all still OK at a glance. [/QUOTE]
