Also, it was the idler pulley that broke. Plastic piece of junk.
-
Does anybody make a quality steel replacement idler pulley?

The factory didn't apply loctite to the nut that holds the door lock on and it just spun right off.

Go to another shop. Any decent shop will be able to turn the engine and cams by hand and do a compression test and/or leak down test to check for bent vales before throwing parts at it.

I bought my 04 Aveo with a bad timing belt (plastic pully failed) ... I pulled the head... had the machine shop replace the bent valves, complete valve job and resurface... New belt, pullies, seals, water pump.... that was about 7 years ago. Doesn't burn a drop of oil and passes smog every time. No reason to replace the engine with one of unknown health.. especially if your old one was quiet and didn't use oil. The valve stems are so small... they bend super easy...so even though all pistons had some dings...it doesn't hurt in any way... (I'm a 40+ yr mechanic)

The pullies fail when the bearing grease is old and dry.. causing the bearing to over heat and melt the pully. When I did my Aveo about 7 years ago there wasn't a metal pully available (maybe now?) ... If you replace everything every 60K miles you should be ok with the OEM stuff. If you ever overheat the engine I would replace the plastic pullies immediately... assuming the head gasket didn't blow....
