New Class Project
As I posted in my intro, I'm in school for automotive mechanics. Well, yesterday, as there's 32 students in our class, the teacher led us over to a group of engines on stands, mostly import 4 cylinders, and told us to pick an engine and a partner, and that engine we'd rebuild. Not liking any of the import engine up front, I moved to the back, where I spotted my prey. We'll be working on a 2006 L61 2.2L Ecotec out of a Chevy Cobalt. The only Ecotec in the room. I figured I'd post a build thread of the engine and document the rebuild here.

from the looks of it thats not a cobalt engine because of the tube running down where the coil packs should be think its an older model cavy engine but not much of a difference really

it's an extra part not connected to anything. the yellow thing is the removable handle for the engine hoist thing. I forgot what it's called. Tear-down starts tomorrow.
As for plans? Tear down the engine, measure each and every individual part, including tearing down the head, and then putting it all back together. They had a 3800 and an early 90's Chrysler/Mitsubishi 3.0L V6 (which was picked by one group), a Ford 3.0L Vulcan, a Ford 2.0L CVH (picked by another group), but other than that and the ecotec, there weren't any Domestic engines. The ecotec obviously isn't a very well liked engine in the school by students (teachers love the engine) as I had to move 3 other engines out of the way to get to it (including the 3800).

Today was the tear-down. What a piece of cake! This is the easiest engine I've EVER worked on. The one that gave me the most trouble was the accessory chain. Everything else was cake. I was uber superised to find cold snap connecting rods. We started the teardown at about 7:50 and finished at 10:40, with a half hour break in there. Time just flew by. It was so much fun.
And without further ado.... PHOTOS! I was more enticed as we went along and forgot to take more pics. But I found a note inside the head when I removed the valve cover...

Tools needed:
flat tip screw driver
10 mm socket
13 mm socket
15 mm socket
ratchet
torx socket.
That's it.
This was the FIRST engine in the class down to the bare block, closely followed by an F22 Honda Accord SOHC Vtec motor, and then a few others. The 2 engines that gave the most problems in the class? A Volkswagen ABA 2.0L SOHC 8 valve I4 (from a mark 4 Jetta), and a Ford 2.0L SOHV 8 valve CVH from a 1997 Escort.

ugh. almost finished. Now all that's left is working on the head. We had a setback when the bolts holding the engine to the stand failed. So as a result, we're now behind most people in the class.
Here's from all the measurements taken.

Today's updates from class.
And the nest thing that pissed us off. The Valve spring, retainers, and keepers for these 2 valves were MIA. Went back through our pictures to be sure and sure enough, they were missing when we got the engine.
