Ok - here's the story. I have a 1994 Honda Civic Si that I bought used with 127,000 kms. It's now at 223,000 kms, and I have yet to replace the timing belt/water pump. People keep telling me that I need to replace my timing belt, but my father insists that it's a non issue, and should only really be replaced when it breaks. I've also heard that, if it breaks, you can kiss the engine bye-bye. Other's tend to disagree. I'm not very car-savvy.... Should I spend the extra money in preventative maintenance to replace the belt, or should I leave it and wait until I have a problem with it? Any help would be greatly appreciated! Moe.
