Review on Enhance Engine Precision with OTC (6680) Cam Tool Set for Ford 3.9L 4V Engine by Rodney Harris

Revainrating 3 out of 5

A second bar to hold the cams would be better as the first set of cams rotates out.

Must do the job. The pins in the gear holding tool were not tight enough, had to be welded on the first time the tool was used as they came out and almost fell into the engine. A second cam lock would be better than the first set of cams, which twist when the rod is moved to a different head during a procedure.

Pros
  • Brings joy
Cons
  • The list is getting long.
