ATM the only plan is to get it running! :)
After some digging through my build thread I found this picture.
Here is the 2004 block. Noticed the black flanged area.

Here is the 2007 block. Notice no black flange or holes. Looks like the 07 valve cover is going back on, or I guess I could plug that port.

It seems odd that they would even have that huge breather there in the first place. How much blow by are you getting that you need a 1" vent hose on top of the PCV valve and normal oil passages in the head/block?!?
Alright, time for the weekend update (yeah, a little late :) ).
So, let see where to start. First thing I did was solder the oil pressure sensor back together.

Next I tried installing the intake manifold since I had to remove it to get the engine into the car. I gotta say, it was a tight fit. I had to flip it around from what the picture shows and go ports first, and even then I had to shove it in there after removing the EGR pipe and a few other lines.

So, I got that secured and the throttle body mounted up. Next, the injectors and vacuum stuff was all hooked up.

Then, I went to install the intake plumbing only to find it was a bit damaged.

And the airbox is damaged too. There aren't enough functional bolts left to seal properly unfortunately. So, anyone looking to sell their stock airbox and rubber tube shoot me a PM.

In the mean time, I did a quick duct tape fix.

Next up was to fill up the fluids. I'm running 100% water right now to do a flush of the system.

At that point I hooked up the battery and gave it a go. It took a bit of cranking, but it eventually fired up (no exhaust hooked up yet). After shutting it down I heard some dripping... I looked under the car to find a nice pool of clear liquid. But, I had to head off to church, and then we had friends over so I wasn't able to look at it anymore that day.

So, tonight I took a look at it and ended up finding this. Which one doesn't belong? :)

And I took that injector out to find this nice o-ring. Simple enough fix though! It probably happened from all the messing around with the fuel rail as it was attached to the fuel line the entire install.

Woohoo! It lives.
Glad you figured out the puddle under the car wasn't anything serious.
I just got back from my first drive in an Aveo! :)
I got the new o-ring installed and put it all back together. I can't say much right now as it was rainy and I took it fairly easy on the car. The check engine light is also blinking, so I have to figure out what that is (no readable codes on my scangauge). But, its very nice to have the car operational.
most of the time blinking means misfire. (you supposed to not drive when flashing)
good luck bro i just got my truck on the road ater 2 years
Congrats on the first drive!
Hmm... 2005 sedan - did you find it to ride smoother and quieter than you were expecting??
Thanks guys.
Yeah I did a quick google search and found that out too. It really wasn't idling poorly or noticeably running bad at all. Guess I'll check the plugs and stuff tonight.Quote:

Shifter throw is long, brake pedal throw is long, the power steering is very light (makes it harder to 'feel' the road). On the nice side, it runs very smooth even with misfiring. :) It also has a decent amount of low rpm power for such a small engine. I think I had shifted to 2nd @ 5-10mph or so and it had no problem just moving right along.Quote:

Now... what next? :) I have a few plans, but those are for another thread.
So, how was the first commute?
Learn anything new? Pros & cons?
The commute was relatively uneventful. Engine light came on again flashing. This time it also had a code, P0300 which is random misfires. I honestly can't tell they're even happening. I'll figure it out though.
The car felt a lot better on dry road. I still very much dislike the shifter slop and long throw of it. The suspension also seems to be very clunky. Other than that it was fine. But, it looks like I still have some work ahead of me.
Shifter slop might be bushings. I didn't notice the shifter bad in the last Aveo I drove (also '05 sedan).
1st gen VW Rabbits were bad for worn out bushings in the linkage. I got a kit for several of the ones I had.
Wonder if he was towing something when the timing belt broke, and what he was towing lol.
Thats a good idea. I didn't notice the slop in the engine bay shift parts. I wonder if its on the other side. I'll have to check it out.Quote:

Cool to hear it's running... BTW those stock air box bolts are junk! Mine all rusted and broke. I used some others to fix. I also broke a corner tap off the box removing a bolt.
Well, I worked on the ignition misfire problem tonight. No dice though. I replaced (swapped with 04 components):
plugs
wires
ignition coils
Nothing worked. Looking for some ideas now.
Still thinking about the ignition problem. I might wire up the O2 sensor from the 07 engine to see if that is the problem.
Also, I just ordered new front strut mounts. Rockauto.com had them very cheap, $14.11 each. I couldn't find them locally for under $22/ea.
I was thinking this over this morning and I'm really thinking its the O2 sensor. The code doesn't pop up for ~20 seconds after the car has been running. Thats just about as much time as you need for it to go into closed loop mode.
I had planned on changing it out last night but had problems getting the old sensor out. Its a pain trying to pull exhaust parts on a hot engine. :)
The O2/Vacuum sensor socket (the long one with a slit in the side for the wire) is an irreplaceable tool in a job like that. I never thought they existed, but when I needed to take it off, my dad enlightened me about it. I think you could even take out the upper O2 sensor with the heat shield still in (I could be wrong though)...
Well, the new O2 sensor went in last night. Didn't help. So, still thinking about whats giving me this error.
I also got the new airbox from serega installed. Its nice to have one that actually seals up to the filter.
How many miles were on the Aveo when you bought it?
108k
As an update to this thread, I haven't really done anything. 8-[ Still have to fix the front suspension and check engine light.
P0300 can be tricky. Or can simply be the crankshaft position sensor. You may have a bad one on there. The wiring for the sensor may be messed up or damaged. The 04 and 07 sensors might be different and incompatible.
Hard to know since you never saw either engine you have there actually running in a vehicle.
A problem with a specific cylinder would be a p0301-0304.
A fuel pressure problem may cause something similar. Harbor Freight sells a good, cheap gauge set that will work on about anything.
P0300 can also pop up while driving down a rough road- which is not your case because I understand the light comes on without driving?
Yes this is my first post. I just bought an Aveo today and read this thread front to back and wanted to chime in based on my own experience. Thanks.
Thanks for the tips Abe.
I have thought about swapping the crankshaft sensors. Its kind of burried so I haven't resorted to that yet.
Fuel pressure I don't think is a problem. I've run the engine to fuel cut a few times and it pulls fine all the way.
Why might rough roads create misfires? I've never had a problem with any other car I've ever driven around here...
The rough road sensor prevents the ECM from triggering a misfire code when the road is rough. It would not cause a misfire if it was bad. I doubt it would prevent the engine from operating in closed loop too.Quote:

Is it actually misfiring? A vacuum gauge may tell you what is going on.
If somehow you had an off balance flywheel or clutch it may have a similar effect.
Good luck. I'm anxious to hear how the story ends!
I swapped the crankshaft sensor last night It didn't help. I cleared the code and it came right back.
Damn
Have you checked if the car is still under power train warranty by some chance? :shock:
Nah, its an 05, I'm sure theres no warranty left.
This weekend I pulled off the 07 intake manifold and put the 05 manifold on the engine in case it was cracked or there were any other problems that might be causing a vacuum leak. Again, no dice. I'm really running out of things to replace!
It's usually the very last thing that you replace that fixes the problem... :P That's what happened in most cases when we were fixing a problem with the jet... :lol:
it's always the last thing you replace that fixes a problemQuote:

LOL... good point. But it's often not the first... or the second.... ;) Especially in elusive problems like that...
I finally called up the local garage. Their "drive ability guy" is on vacation atm. Looks like I'll get it in late next week or so. I'm almost out of ideas.
One thing I did remember though. When I reset the codes on the engine, it stays in closed loop for a little while. After a while it kicks back into open loop. I guess in open loop mode it must not be misfiring because it runs fine. I should redo my tests with the codes reset to see what happens.
I can guess and say you need to perform a crankcase position sensor relearn procedure, your dumping some fuel for some reason, or you cat is slightly clogged causing a back up..
but its probably something more simple.
I did loosen the bolts before the CAT and fired it up to see how it effected things, it revved even slower than normal, so I don't think its the CAT.
It would be great if it was something simple that I'm just overlooking.
If you have any other ideas I'm all ears.
Put two cans of NOS energy drink into the engine oil....... :-k :lol:
I finally took the car to a local garage yesterday. They diagnosed it this morning. Apparently, it needs a crankshaft relearn procedure done on it. They borrowed a tool from another local shop, but couldn't get it to work. They suggested I take it to a dealer to take care of this.
