Mistake Number 2: Labor is going to be cheap. Labor will not be cheap for this repair. This is a labor intensive process.

Mistake Number 3: Only addressed the timing guides. While the engine is ripped down there are number of other things that should be addressed at this time. For instance the cooling system should be overhauled ( all hoses, thermostat, o-rings, water pump, etc.), timing chain, CCV system, tensioners, intake gaskets, valley pan gasket cooling tray, etc.
