5.0 out of 5 stars Just the thing for overhead cam engines, March 29, 2010

I bought this tool to service the valves on my classic Triumph overhead cam engines, namely the TR7, Stag and Dolomite Sprint. An OHC engine needs a tool that will reach well down into the tappet bore to compress the valve springs. This tool worked beautifully, and it would work just as well on pushrod engines also. Very sturdily made. This is the only valve spring compressor I'll need in the future.
