Yes. I'm sure that is what's happened here. The shims are too soft. The go=
lden shims are hardened and probably grade8 with no stampings or identificat=
ion. Golden color same as grade 8 hardware. The other shims are stamped, val=
ve spring shim and Houser, Blufton, Ind. =20

> One thing I found was that some of the valve spring shims were disintegrat=
ing. There are two different types of shims, one golden/yellow and one plai=
n silver. The problem is that the silver ones are heavily worn from the spri=
ngs tearing them up. The golden yellow shims look as installed, with no vis=
ual wear and they don't seem to have been rotating. It obvious the springs o=
ver the silver shims were rotating and causing the heavy wear. Perhaps thes=
