97 Camry Shim Replacement 

This is an excellent informative and instructional video. Thank you.

You can use a tool to depress the lifters and change shims without removing the cams. I've never had to readjust the valves on my 2001 Camry but I did change shims on my 1979 Suzuki GS1000.

With changing the shims, what problem does it solve?

Good job can I have the book so that I can use it to do my valve clearance
