2005 Aveo 5-spd sedan - timing belt broke - being repaired

[petrified.rabbit]

yes, but from what i have seen, you can swap a 2.0 to a 2.2 in the daewoo.

the 2.2 would be a good build for an NA build, the only major difference between the 2.0 and 2.2 is the connecting rod are longer and the block is taller in the 2.2, otherwise you can use all the parts from the more popular 2.0.

so assuming that is correct (the guys there know there stuff), then the 2.2 has a higher deck height but otherwise has the same dimension for the most part..

there is also a list of other engines you could chose from..

Thanks rabbit. I'll do some reading on that site.

Another quick update of mostly pictures. I got the clutch & flywheel removed tonight to get it on the engine stand. Of course the bolts were too short to get it on the stand so I'll have to go get some tomorrow. In the mean time I started removing other things...

Pressure plate, clutch & flywheel.





All taken apart.





Flywheel removed.





This is the passenger side motor mount. Apparently the previous owner, in an attempt to fix the car decided it was wise to only put 2 of the 4 or 5 bolts back in to hold the engine up. Well, they both bent. I unbent the one still in the mount and pulled it out...





The other didn't fare so well. The other end of it is still in the block.





Removed the motor mount.





Removed the crankshaft & timing pulley.





Interesting note, the crankshaft and timing pulley are one piece... kind of. It seems the bore and keyway are pressed in. Odd design I've never seen before (not that I've seen a ton). EDIT: The smaller timing pulley actually pulls out of the larger pulley. Mine was just gooed together.







And the timing belt cover all removed.

So I'm guessing you didn't find any hidden missing teeth on the belt when you took it off?

[Daox]

Ah yes, I forgot about that. Aside from being beaten up around the outer edges (opposite the toothed side), the belt looks good and the teeth all seemed to be quite intact. There was no cracking or anything that I could see.

So then the "snapped timing belt - being repaired" is not quite correct then? Or was it ultimately the reason for the engine failure?

[Daox]

Well, at this point I have no idea why the engine failed. But, the valves definitely smashed into the pistons somehow. There are score marks on every piston (in addition to the shallow stock cuts).

[petrified.rabbit]

without seeing the car or knowing what the mileage and such are i would be willing to bet the tensioner failed. thats probably at least as common as a belt actually breaking, and probably even more common since that is typically what beaks belts.

hows the build coming along?

There are no updates since the last post. I have a small crew of in-laws & friends staying over at the house this weekend to do some work on my house. I'll get back to the car during the week.
