Review on Comp Cams 8921 16 Competition 892116 by Jonathan Arroyo

I love that a lot of people have to buy engine components when I can afford it (budget). I bought these jacks 2 years ago and they sat with other parts of my engine project until I was ready to build the engine and I just installed my sealed COMP jacks and a few of them broke down and called themselves COMP Cams and a year later yourself. when new in a sealed box. I would strongly steer clear of this product as it would cause severe engine damage if I used it. I'm not the only person who experienced the poor quality of this product.
