Never heard that. I know that the last gen 2.2 OHV engines had some problems, but the Ecotec has been a pretty bullet proof motor so far.
The Ecotec is made all over the globe. I do belive that the majority of the engineering was done by Opel.

The 2.2 that is found in the late Cavi and up to 2007 Cobalt have been the same engine.
The new 2.2 and 2.4 that is showing up more and more are all of teh 2nd generation Ecotecs. They use Variable Valve Timing, and the 3rd gens are already here using direct injection.
4th gen will use GM's new HCCI (Homogenious Charge Combustion Ignition) "diesel" type technology, using no spark to ignite the air fuel mixture under light to medium loads. It's given test cars a 20% increase in fuel econ. Expect the HCCI out soon.
