Wondering if anyone out there has seen or heard of cylinder lining seperation as a failure mode of the 2.5L engine. Working on a friends that got the "Just Brakes" treatment. Pulled the head today and found cracks in #2 and a chunk missing from #4 in the steel only on both. Chunk turned into slag. No cross leakage. Car is higher mileage, but this just seems too odd for an engine to go this way. Any help/valid comments are appreciated.
