Replacement cylinder leak tester for Calvan 38900, also known as Snap On FRT10-1. Eliminates the need to remove to the valve cover to determine the valves are closed. Commonly used with the Calvan 38900, Time Sert 5553, 5600 and Calvan 39300 3V kits. Can be used with other thread repair kits also. Used on sparkplug holes that have a "well". Helps prevent valve damage caused by reaming/drilling and tapping with the valves open and also helps to isolate the cylinder being worked on. Debris can then be removed with compressed air without being blown past the valves. *Not for use when spark plug holes are near the surface.

Great tool to know when valves are close, useful to repair spark plugs thread. I fully recommend it.
It is a lifesaver for someone working by themselves.
Works exactly as advertised.
Very convenient tool, fits in the top of the spark plug/coil tube and pops out under air pressure when the valves are fully seated. The only problem I ran into is that the male air fitting is not easily interchangeable. The threads are smaller than standard 1/4" NPT and thus the fitting could not be replaced with any of my regular Milton male couplings. I had to change out the female coupling on my air hose before I could use the Calvan tool, then swap couplings again to use my air ratchet.
Got to have tool.
