Bingo. Surprisingly it still runs, it is just noisy and making an oil mess.

I am not sure, but it would probably be easiest to take the ECM, BCM, TCM, engine harness, ignition theft module from the donor. And then I don't know how the Restraint computers or the ABS and traction control computers would work, since they interact with the BCM and ECM.

The GM LAN and CAN BUS are probably different.

You may have trouble with the DMV, and insurance company.

Cheaper to get a matching used engine. But, you seem to be up for a challenge.

Every car I've had since 1970 has had a PRDIL, made famous on "Green Acres". Sometimes marked PRD2L. The operation of the "I" is covered in the Owner Manual, available through the link in my sig.

All of the posts I have made except the very first one are not visible to me, and I still get the page saying my post must be aproved by an admin. It is my understanding the 2.2l harness and the 2.4l harness are identical except for the 3 additional connectors used for the vvt on the 2.4. I wouldnt think the sensors are different even though the years changed. I understand the gmlan and can bus difference, but that is the method the modules talk to each other, not the modules to the sensors. Is there anything different between an 06 2.2 and 09 2.2?

That definitely would be easier, but the 06 is my wife's car, and she is very partial to it.

Hadn't thought about this in a while and wanted to update everyone. The 2.2l from the 2009 is a vvt engine just like the 2006 2.4l. The engine bolted up fine. To avoid problems with computers talking to each other, I used the engine harness from the 2006. The intake on the 2.2l was cracked so I used the intake from the 2.4l. The 2.2l was a flex fuel engine and I was worried the injectors flows would be off so I got injectors from a early cobalt 2.2l at the local u pull it. The exhaust manifold was cracked on both of them, so I purchased a new exhaust manifold for the 2.4l and bolted it to the 2.2l. I used the 2.4l cat converter setup. The swap worked fine. The car runs and drives fine and I have put 10k plus miles on it since the swap and no issues.

Awesome, thanks for the update!
John Lennon was right, there’s nothing you can do, that can’t be done.
Enjoy the ride!

I fixed the unapproved posts. I don't know what that was about.

I'm glad to hear your wife's car is running well, but what about your project? Any plans or work started on the V8 2009?

Unfortunately, The company I was working for closed and I lost the fringe benefit of a huge climate controlled shop. I have a new job. I am working on building a garage for myself, I really dont want to take on a project like that without at least a roof over it. I did buy a wrecked pickup with a 6.0l lq4 and a 2wd 4l80, so I have a donor, just need some space.

Wow, sounds like real interesting swap. Please keep us updated when your garage is built.
