2008 2.2 Ecotech Engine Rebuild or Replacement?

The motor has 74k on it and I was told by a repair shop the timing chain tensioner failed and the motor would cost 5k+ to rebuild, I am debating on rebuilding it myself or just buying a new engine to swap, I have rebuilt engines before I am not a professional mechanic and won't get it done over Nite but any one who has rebuilt this motor have any ideas or advice I would appreciate it, I know it is a big job and can be time consuming but I am up for a challenge.

You can probably get a junkyard motor with reasonable miles for like 500-600 dollars. You and a friend can change it in a long day and a case of beer. I would say this is your best bet. You can tinker with the dud engine after at least you'll have a car on the road. And for GOD sake change the tensionner on the replacement motor before you start it up.

Every minute spent angry is a happy minute lost for ever and ever!!!

you can buy a newish engine for the 2.2 for way less.... the shop is probably giving you the price for pulling the current engine, buying another one, and installing it... 5k is pretty steep for repairing the 2.2 unless they were buying everything seperately.

2008 2.2 ecotech

Wow thanks for the fast reply, Coby7 sent you a p.m. I have another vehicle to drive in the mean time, I guess what I'm getting at is if I'm going to all the trouble of dropping the motor I want to put something reliable back in, since I don't have A shop and this will be a garage event how technical is this motor to rebuild? It is funny because I have built a few small block race motors but this little guy has me weary, just got done with a 97 cavalier but this motor is much newer and technologicaly advanced.I have priced rebuild kits plus new valves and I'm coming in at around 1500 to get back to stock.

Some where on one of the forums, there was a guy the blew the 2.2 in his car and put in a 2.4 with vvt, he had to wire in a sensor and get the ecu reflashed with the 2.4 tune, but he said it works flawlessly now.

You would have to pull the head to make sure pistons aren't punched and connecting rods aren't bent. If timing chain had jumped more than one link and the garage cranked the engine to do a compression test well you see the results no compression on any of the cylinders anymore because they probably bent the rest of the valves.

Rebuilding these motors is super easy. For 5k, you can make it bullet proof.

Why not take this opportunity to drop in a better motor? LSJ maybe?

.... LNF/LDK brand new and complete, is something like 3000K from ZZP...

But if you swap from the 2.2 to any of the 2.0s he would need a new trans, clutch, I also think he would need to swap the shifter assembly. Also intercooler, downpipe, exhaust, intake manifold, stock/aftermarket intake, charge pipe, ecu, bcm, tune and a bunch of other supporting mods to make either of them happen.

It would be way easier and cheaper to just build the stock 2.2 for boost.

I'm just saying that's $4000 off the rip, and then you still need the supporting mods, and other random pieces to make it work. To build the 2.2 and add the supporting mods you would need you would spend quite a bit less, because there are kits that already have everything you need.

You'd have to do many of those things anyways to build a 2.2 for boost, and add internal work on top of that if you're serious enough.
