I got a 2000 Focus ZTS. My son parked it at work and it never would start after that - sounded like the engine just spun with no compression. I pulled the timing belt cover and saw a few teeth missing from the belt. I did a compression test and of course got no compression. After resetting a new belt with the notch on the harmonic balancer to 0 TDC ( I probably should have pulled the alignment pin and set with a pin) and the cams - I reassembled to the point to do another compression test and this time I got 115 in cyl #1 and then 60-65 in cyl #2, #3, and #4.

Any ideas? should I try and reset the belt with the alignment pin? or just throw in the towel and pull the head? If I would have damaged any of the valves would I even get compression in cyl 2 thru 4?

Regards,
Jim

Here is the answer?

"I did that changed the cam. I like the crank pin. The crank likes to mive a little when setting the belt and it make it fool proof to reset the crank. My boss(30 year mech) set the crank first to top dead then I installed the pin he was off 1 tooth. And I installed the pin faster then he set top dead his way."

Hey that's me^. and ya the crank almost always moves some and TDC isn't the same as the pin as pointed out.
