so if you can succeed with using a "Low Impact Leverage " solution instead. and set up subtle internal Crank conditions that display unexpected or unexplained Engine Vibrations later on. using an Impact Wrench to pound away for long periods of time on Harmonic Balancer Bolts to loosen them from Crankshafts can cause many of them to lose their Casting or forging "Tune". Then the Breaker Bar will have enough Freedom of Movement to allow you the chance to loosen that damned HB "Jesus Nut":Īs a Rule. using pieces of custom cut 2"X4" Wood wedged in and onto the Frame-Body areas adjacent the Wheel Well so that a Socket can engage with a Longer 1/2" Extensions can clear the body. There are also a few 2.2L Ecotec Youtube Videos that show some variations on this Bracing Theme. Elevating the Vehicle much higher than normal (safely) may be required in order to have enough "swing" room for the Extra Long Breaker Bar. it may provide you with some alternative ideas on how to "Beat Archimedes" at his own game of gaining some additional Leverage to Break the HB Bolt Loose and not damage anything. While the information in this Link covers that difficult action on a 2.2L Ecotec. If you finally decide to Pull The Harmonic Balancer. this first one from Cloyes will show you how this job gets done with their Complete Kits. While the rest of these Videos are anecdotal and/or hands on repairs of the Ecotec Timing Chain Issues. for BOTH the Front and Rear Timing Chains situated in the very front of your Ecotec Motor: the solution to this matter will be a fairly involved mechanical repair requiring the R&R of the Timing Chain Set. if your own diagnosis proves this problem to be true. the 2.4L Ecotec Engine Platform shared by them all will accurately describe what may be happening inside of your Engine. An inoperative Timing Chain Tensioner or Broken Timing Chain Plastic or Nylon Chain Guides will often presage the Poor Performance issues in these engines display.Įven though these videos involve other styles and types of vehicles. it may be having Timing Misalignment events that are sufficiently out of OEM Spec to cause the correlation between the Crankshaft and the Dual Overhead Intake and Exhaust Camshafts to fail.
If the Engine sputters and shudders and is making noises under the front of the Valve Cover. but rather are CENTRAL to the issue of what is actually going wrong inside of your 2.4L Ecotec Engine. I'm very sorry to suggest that the P0016 and P0017 are not secondary codes that are being triggered by something else as the causal events in the rough idling or performance of your vehicle.
