Ok. First of all, a disclaimer - I wasn't looking for one of these predicted results!
My query was like "how to know if a timing belt has been changed". After driving a car for 5-6 years back in my country.. all I learned about the technicalities of cars was limited to refueling it, excellent gear shifting, and racing with odd one outs in random traffic. I am also proud of the fact that because of me and my driving skills, a number of human beings thanked God sincerely that He saved them, who knows that might be a turning point in their lives to submission to All-mighty :D
Anyways, I wanted to search for some articles about discovering the last time a timing belt of a car was changed.. there was this civic (yeh still looking for a car), the owner didn't had any related receipt/records, so I thought that there must be someway for a mechanic to get to know this by a brief inspection.. that's it, over and out.
