2005 Aveo - Crank, no start

[gearhead1]

So the battery was dead. Charged it. And still getting the whirring sound on start. So I took the upper timing belt cover off and sure enough one of the pulleys is busted and the belt is shreded. So now I will need to take the cylinder head off to inspect the valves and cylinder head for damage and then go from there. If the cylinder head is damaged then it wont be worth fixing, depending on the severity of the damage and if it will need to be replaced. I dont mind replacing valves and then putting it back together. But a new cylinder head might cost a lot.

Valves will be bent. You can make book on it.

The head normally does not get damaged when the valves bend. Take it to a machine shop to be checked if you have any doubts about that, but a valve kit, head gasket/bolts, and a timing belt kit should be all you should need to buy in order to get your vehicle back on the road.

Yes, the head itself is usually ok, but I would add that some of the valve guides almost always crack when this happens.

Been through it and yes, it is expensive. The head on my 2004 is now the freshest part of the engine. If you're in the Southeast Massachusetts area and still broken, you can have the entire car for less than what that valve job costs. Just took it off the road in December. I'm new to the forum, if there's a market place I'll post it with some pics.
