Hello, I own a 99 Mitsubishi Eclipse RS 2.0 DOHC 5 speed trans with 82,532 miles on it. Recently, I had my Timing Belt and Water Pump replaced. The mechanic put the timing belt back on in the wrong position on the wheel, off by 1 tooth. He drove it up the road and back before discovering it and then had to reposition it. About a month later my #2 spark plug fowled, so I had them do a standard Tune-Up replacing the plugs and what not. Not long after that, my engine light came on and the code came back as insufficient EGR flow or possible vacuum leak I was told. When I had that checked, they did a cylinder compression test because they stated the engine sounded like it was missing. The compression test showed that the #2 cylinder was 75psi, half of what it should be and not even enough to fire the cylinder. The #4 cylinder was also deteriorating at 125psi. They said it is probably a burnt valve. My question is when they replaced my timing belt incorrectly and drove it, could that have damaged my engine and caused all this? Thanx!

If it only was one tooth out of time then no it would not have caused this. It would have bent the valves and may have knocked a hole the the pistons. Was the car running good before all the work was done? If so it could have bent the valve.
