I doubt that fixing it is going to be a viable option due to overall cost. The family mechanic looked at it and let us know that the Pulley that the timing belt attaches to came off completely bending/destroying the valves and scoring and breaking the pistons. He had quoted us $3000 to fix it, which involved getting a new engine.

Personally $3000 is way, WAY to much to put into her car and honestly, is a bit pricey to purchase and install an engine to begin with. I haven't owned a Chevy in around 12 years at this point but back in the day I had a collection of 3 ThirdGen F-Body's and a bevy of other GM vehicles... I learned most of what I know about cars on those vehicles... but now a days I drive a MkV GTI and am a huge part of the Euro scene, so I don't really have a ton of connections anymore. That being said, my buddy who is also a Mercedes Master Tech and authorized Renntech dealer offered to install a new engine for $600, so I went and found an engine which is $620 with free shipping and has 61k miles on it. All we need to do is get the car up here.... (Most likely going to cost $250 or so), so with everything (Labor, Engine and Tow/Pickup) we're at $1470 for an engine that has half the miles on it as her original. Which is a SIGNIFICANT decrease in price over the $3000 she was originally quoted. With all that being said, I haven't looked at the car as its over 2 1/2 hours away, so I'm basing all of this off of the info that was provided to us by her family's 'trusted' mechanic. But the damage and diagnosis that was provided matches verbatim most of the other cases I've seen around the 'net regarding the timing belt slipping on this particular motor.

Why didn't she change the belt? Who knows... she's been a roommate for 6months and the GF of my best-friend for a year, so it hasn't really been something that I've really been involved with up until now. Shes a good person and I'll do whatever I can to assist in this as no one in her family, or her boyfriend know anything about cars. But I won't lie, I don't know much about Aveo or the 1.6L E-Tec II's other then what I've read today on this site and on Wikipedia.

I just feel like the engine swap is the least expensive way to get her back on the road, as a new car isn't a solution at the moment... if I'm wrong def let me know, but I just can't see getting a head rebuilt and then replacing the pistons being a less expensive way to take care of the diagnosed issue then the swap.

I just want to make sure that if there are any other accessories from the '07 that I might need, that I get them sent with the engine.

I appreciate you guys responding though!
