Broken Timing Belt/Chain Question
I own a 2007 Cobalt LS 4D... here's a brief synopsis...
Check engine light, return code P0016 (Cam Shaft Alignment Sensor or Timing Issue).
Engine started fine, I experienced 1 hard start, drove about a mile to get dinner and back, next day... wouldn't start. Fast spin, with no engine turn. Obvious timing belt is broken ... what other problems 'could' a broken timing belt/chain have on the motor? Dealership Mechanic talked about whether or not the motor was a 'tolerance' motor (which he couldn't tell me without looking in the book, and a surcharge)... (which means the valves could be bent as well?) are there any other internal motor issues that could have caused this? I did have low oil for my last change, but no visible leaks (puddles), and I've checked it since the last oil change ... levels seem fine.
I was originally told the car was still under warranty, paid to have it towed the dealer, he calls me back stating it's NOT under warranty and wouldn't give me a 'general idea' of the cost for repair. Stating the he wouldn't know until he got in there ... in my mind none of this is adding up, but this is a fairly reputable dealer in my community. Obviously, if the car was not under warranty, I would have taken it to a cheaper (and yes, trustworthy) mechanic. But I'm in $50 bucks for a tow now, I feel he simply lied to me about the warranty knowing I'd have brought to the shop.
Any advice on timing belt motor issue would be greatly appreciated!
