Hello Friends,
</div>
<div style="font-size: 12pt; font-family: helvetica, arial, sans-serif; color: rgb(51, 51, 51);">
I've removed and disassembled my TR3 engine after 7 years, 19 race events and about 5500 miles since it's completion.

The crank and cam look excellent as do the bearings, both mains and rods.

One thing I found was that some of the valve spring shims were disintegrating. There are two different types of shims, one golden/yellow and one plain silver. The problem is that the silver ones are heavily worn from the springs tearing them up. The golden yellow shims look as installed, with no visual wear and they don't seem to have been rotating. It obvious the springs over the silver shims were rotating and causing the heavy wear. Perhaps these shims are too soft.

Can someone enlighten me on this?
