Review on Proform 66792 Dead Center Locater by Luis Thompson

Thread fits Toyota 20/22R sockets but is barely long enough. I had to run the adjustment to its maximum length so it could be secured without a lock nut. Nearly found true TDC on the first job, but during my test run to double check my values, the threaded inner stop rod buckled and the piston passed without even feeling it turning by hand. Piston pistons, but pretty minor, I guess I live with that. I think it's good that the stopper bent more damage, but I'd be happier if it stopped the piston instead of bending it. Be careful with this tool and really feel for the stop, especially when fully extended and when the angle of the piston relative to the piston is small. It can be subtle. Outside the return window and I'm wondering what to try next.
