    How to swap shims with no spare shim?

    I have two valves out of spec. How do I take them both out and swap them ? I tried the leaving the zip tie in the valve to rotate the engine but the can love got stuck on the lip of the cup. That was a mess to press the valve so I could unstick it. So what's the secret?

    Ideally, of course, you would want a spare shim, but some have reported using coins as a TEMPORARY shim.

    Don't know if half-dollars or 'silver' dollars will work, but a quarter should fit fine.

      Use the gold dollar coins that are slightly larger and thicker than a quarter.

        Put your approximate earthly location in your profile -- there might be a friendly GS-er in your neighborhood with some spare shims.

          Hi,

          You never want to turn the engine with shims missing. You need an extra shim, or shim-like object. There is a "shim club" in the forum that offers free exchanges. See: GS Valve Shim Club

          For reference: Valve Adjustments (8 Valve) (PDF file)
          Thank you for your indulgence,

          BassCliff

            I'm banking on that!
            Seriously, I've read in previous posts where you mentioned quarters before. It would be nice to know if indeed they really do the trick.

              As long as they fit in the bucket AND are higher than the bucket rims, anything will work...change, washers, whatever.

                And Chuck, what did you say the diameter was for those things?
                29.5mm wasn't it?

                  The shims are..but a little loose just for a stopper is ok. He can roll the engine with the crank nut and swap out shims. Thing is to keep the edges of the bucket from hitting the lobes.
