Review on Ford 4 6L Engines Repair Tools by Charles Galan

First I would like to say that the cam locking mechanism worked well and I had no problems with it. But the valve spring compression tool is not good at all. I could use multiple valves but if I had to bend the tool in a vise to even work. After a few valves, the tool began to bend so much that it could no longer function. So I went back to the vise to bend it back into place and it broke! Very disappointed with this particular tool. I then bought a more expensive $37 valve compression tool and it worked like a charm. I wish I could buy it first.
