I purchased the Grand Am last July from my mechanic, who had replaced the engine with a newer one, (121000km). Back in December I was experiencing weird chugging and kind of hickup of the engine only while idlling. He said he could not find anything wrong with it. This continued until this past Saturday when it died completely. He has said that the timing chain went on it and that it was due to the fact that I was 3000km behind schedule on my oil change. I'd checked the oil level just the week prior and it was fine, though I knew I'd need to get it done very soon. He is also saying that the timing chain itself cannot be replaced, that the whole engine has to be replaced! Is this true? Also, does it sound as though the earlier issue could have been related to the timing chain, and he just didn't want to bother to open the engine to check?
