time belt Question

...I have a civic (1990, 1.5) and the water pump was damage, I changed it and then I put the time belt and everything back. I use the marks for the time belt but my question is how do I make sure its ok, I mean like when I start the car it sound kind of diferent, should I check something? Or if its wrong should it even start?

take the rocker arm assembly off,
you need to get a compression set,make sure that the valve is not in the hose on the kit,charge each cylinder with compressed air & listen for air leaks,(will only work with rockers off) & you should only hear noise coming from the crankcase,
other then that you could of left the timing belt loose or the water pump propeller could be bent.

If the car started ok and revs ok, then you are fine. If it starts kinda hard and doesn't rev right, then you are usually only a tooth off in either direction. But if you aligned the timing gears the way the manual said, then you shouldn't be more than a tooth off and you just have to adjust the timing on the cam gear one tooth. That's how I did it when I replaced my timing belt after breaking it.
