Is my motor ruined??
I have a 2010 Chevy Cobalt SS 2.2L, i noticed the engine starting to make a ticking noise which after doing some research I am fairly certain is from the timing chain tensioner. As I was driving to work today, my car engine would shut off while coasting (the rpms would drop right to zero, and if I stepped on the gas nothing would happen), but all the electrical systems would still run. I would pop the car into neutral and then turn it on again still while coasting. When I finally hit a red light and came to a dead stop, the engine died and would not turn on again. I can hear what sounds like the starter trying to turn over, but nothing happens other than that. I ended up getting the car towed to the mechanic, where he told me that the engine is seized from lack of lubrication, but my car recently had a oil change (6000ish kilometres ago with synthetic oil) and the dip stick still reads a good fill level. I am strapped for cash at the moment and don’t feel like shelling out thousands of dollars to replace the motor, because I am pretty sure the mechanic I went to is wrong, and it’s the timing chain and tensioner that need to be replaced. I am just curious if anyone on this forum can give me some insight if it is even worth tackling replacing the timing chain and tensioner, or if the engine is guaranteed to have suffered catastrophic damage from the timing chain/tensioner failing?
