Early M272 engines had issues with the balance shaft gears, which would wear out prematurely and cause the timing chain to fall off or fail.
While the M272 is based on the M112 design, the M112's don't suffer from this problem. The M112's and M113's were actually overbuilt, and it's pretty common to see them hit 400k plus miles with nothing more than routine oil changes.
