2002 Mazda Protege timing belt replaced and

If you did not have the bent valves replace then that may be the problem. If the belt has not broken then turning the engine over with the belt removed will bend valves. I suggest that you have a compression test done to eliminate the valve problem. Next is to recheck the cam shaft timing . next is to check the position and firing order of the distributor.

Timing belt. I replaced mine right around 100k along with the pump.

first of all with 3 cylinders 25lbs -1 100lbs. you have a problem with the vavles i think you have some bent vavles thats why low compression on 3 cylinders. check rockers or lifters but thats where it is foresure.

maybe the replacement part timing belt is not exactly the same as the original.

YES, AND YOU SHOULD REPLACE THE TIMING BELT AT THE SAME TIME .

I assume you are replacing the timing belt, so just wactch the youtube video at the link 1999 03 Mazda Protege 1 8L 2 0L timing belt replacement pt 1

they are good for well over 100k. If your engine is freewheeling (that is - if belt does break, no valve will hit the psiton), I would just keep driving it until it breaks or never does.
I am driving my 93 Villager until it breaks. over 150k right now, freewheeling engine.

As for cost, about $400 is my guess.

Ask your dealer service dept if it's freewheeling. check your owner manual too.

every 90,000 to 100,000miles and yes it is strongly recomended to replace the water pump with it

replacement of timing belt $350-$500. aftermarket shops will try to sell you a package containg a belt, water pump, and tensioner pulley. the dealer will just replace the belt, they might recommend to replace the water pump if there are alot of miles on the car, they will also inspect the pulley for wear.
