I have a 2001 Cavalier with 175,000 miles on it that has jumped time. I was told by the mechanic that I could have a new timing kit put on but wouldn't guarentee that the car would start. He wasn't sure the engine was an interfernce on non interference. I called the dealer and they couldn't tell me if it was or wasn't. Can anyone here give me a resource for finding out if my engine is non iterference or not. Also yes I know the car has a ton of miles on it, I was thinking of getting rid of it in July but last week I had to have a new Cat converter put in at 800 bucks and decided I would proibably hold on to it at least till the beginning of next year to get some use out of the 800 bucks I blew on it.
