Turbos or camshaft phasers?

The turbos and camshaft phasers will wear out not matter how the engine is cared for, they just wear out faster if the engine oil has not been changed, and I mean not 15k the dealer recommends, it should be more like every 4k to 5k with synthetic oil and new filter. You will need to make the call on vehicle condition and listed for engine noise when cold, and then hot.
