One thing to remember. Checking clearance or the lack of it is a touch. Knowing the feel of a gauge as it slides is very important.

Paul, here's a simple (not to scale) drawing that I've just done to show the basic Valve, Bucket, Shim, Cam set up.

The Drawing on the left shows the individual components.
The Blue being the Shim, the green being the bucket that sits over the valve and has the shim sitting in the top of it.
Then above that, the camshaft.

The R/H drawing shows all these piece's as they would sit in the Engine (again, not to scale)
The Camshaft and valve are in a fixed position (relatively)
The "valve clearance" is determined by the thickness of the Shim.
Too thick a shim, .... no clearance.
Too thin a shim, ......excess clearance.



This Dwg. shows a shim too thin (exaggerated) so therefore excess clearance.



Hope this helps.

I like the statement not to scale.

You would have to a bit simple to not understand that from looking at it.

That's what I get on most of the engineers drawnings at work.

Shim under is superior in every single way except servicing.
