timing Chain 2.2 Ecotech
#12
Shouldn't be much play between the two camshafts. I just recently did a rebuild of a 2.2 that jumped and bent 3 intake valves. Once the marks were lined up I double checked by rotating about 30 revolutions to bring the marks back together. Takes a while, but I wanted to insure I wasn't going up have any collisions during startup.
Got about 5k on it now. Good luck, double check everything and keep us up to update.
PS- if just the engine is out. You'll save some headaches by removing the harmonic balancer. Much easier to slip the engine back onto the trans. Unless you went out the bottom with the trans, in that case just drop the car back on it!
Some will argue that it's a one time use bolt. That's fine, I have done this to 4 HHRs. Haven't replaced it yet, fingers crossed I suppose. I found it impossible to drop the engine back in with the balancer on.

The "book" says to replace almost all engine bolts. But none that I can find are actually listed as "stretch" bolts; even the head bolts. They are awfully cheap to be "special".
Strange thing; the LCA bolt that calls for 180 degrees after the torque does not call for a new bolt.
