Can't beat that deal right there!

How much more to do that to an 07 Cobalt SS/SC 2.0? You'd have to move the supercharger off the existing engine over to the replacement.

Update here are come pics

so the previous owner did not Torque down the head gasket he said it was hand tightened. other then that all that needs to be done is the head needs to be faced down with a new gasket the clutch is good

Is that water sitting on the pistons? If it has gotten past the rings Id say your bearings will all be shot. Should have just got a second hand engine IMO
 
Water sitting on the pistons in that situation most likely just came from leftover pockets of water that drained into the cylinders the moment the head was lifted off the block - happens all the time, it's normal. But if the oil that was (is?) in the crankcase looks like chocolate milk, or if there are visible metal particles in the oil or in the oil filter (the oil will look like copper-coloured metallic paint), that's a whole different story.

BUT ... If you have the engine in that condition, it is only 15 minutes more work to flip it upside down and take the oil pan off to have a look inside. It's worth doing.

If you find no trace of metallic-paint-looking particles, it's good to go. If there is metallic debris in the oil pan, it's time to split the cases ... and from the condition you have that motor in right now to having the cases split, is less than an hour of work. Pistons don't need to come out of the cylinders unless necessary (depending on condition of cylinder walls). You can do all the rod and main bearings without taking the pistons out.

Kahuna Power Sports on Steeles, Craig is assigned to my bike (he said a few guys know him from here) he is great guy with extreme bike knowledge so happy he is the one working on my bike. In the long run it did cost me more then buying a new motor usually 1$ a CC(used) but this way at least i have 100% confidence and i know its going to be good, no worries in the back of my mind. Craig suggested that I change the clutch as well so we went ahead and did that along with all new Gaskets. The head was faced down .004 and the Block was .008
here is a update as of March 20-25th (Pictures)

all you experts on here never mentioned to the kid, that he should have done a leak-down test, no more guessing in the future.

I think they are implying that getting your head/block resurfaced won't be the end of your problems ;)

so you think the only thing i did was just resurfaced the head and block? even for you pro's that's a silly accusation
your all keeping quiet... tell me what other "problems" i'm going to see....

You didn't really go into much detail about the repair ;)

The OP took it to a professional mechanic, and one known to have experience with this type of engine, and with a roadracing background. If the head and block were machined, this means said professional mechanic would have taken it ALL apart and inspected everything relevant. (You cannot machine the block or head without COMPLETE disassembly.) This should be the end of the issue PROVIDED that the OP maintains the bike in a proper manner, and that includes maintaining all fluid levels, and next time, if there are all sorts of red warning lamps coming on, STOP IMMEDIATELY and don't try to continue running the engine until the fault has been identified and dealt with!

Who's installing the engine in the bike? I sure hope Craig is doing it, through to the point of getting the bike running again.

As for the statement that we didn't recommend a leakdown test ... Not directly, but it WAS recommended that the OP take the bike to a professional mechanic when it became apparent that the OP didn't have sufficient knowledge or experience. I think the situation was already beyond a leakdown test being a constructive exercise anyway. At a certain point, when you know more or less what a certain test is going to tell you and that it's going to tell you that the engine has to come apart for inspection, it's not much of a constructive exercise to do the test any more ...

By the way, with 0.3mm taken off the block and head together, it is now a high compression engine. Don't cheap out ... use premium fuel from this point on.
