Can a 5.7 engine be out of time to cause engine to "kick back" hard enough to break tooth off of flywheel
Asked by bcayton75 Apr 19, 2015 at 04:16 PM about the 1999 Chevrolet Tahoe LT 4-Door 4WD
Question type: Maintenance & Repair
My daughter has a 1999 Tahoe that had tooth broke on fly wheel, trans shop replaced
flywheel and starter. Mechanic told her to get timing checked that it was out of time and
caused engine to "kick back" and break tooth. The Tahoe started just fine and after
driving it four times it broke tooth on flywheel & starter again. He will not fix because he
says he told her what caused it & she didn't have checked. Is this a possible cause??

Yes it can be. Is it controlled by an electronic module> Have the codes read at the same time the timing is checked.
Here's a good question. If the mechanic knew it was out of time and it was breaking a tooth, why would he repair it and NOT check the timing himself? It would only take another half hour to adjust the timing if it was out. Seems ridiculous because as soon as he started it, it could have kicked back and done it again before it left the drive way. Makes no sense. How long did you run it before it broke another tooth?
My thought too, why would not tell her to get that fixed then bring it back. GM Service Bulletin says it is Crankshaft Positioning Sensor. It started 4 times. To his defense, he only works on trans. He did tell her to have it checked but should have told her not use it until.
Alas, was this a GM dealer? If so, raise holly hell s they have the personnel and means to make sure it is fixed correctly. If not, you may win a refund but it will take time as courts are slow. This is a lesson on goi8ng to a shop that costs less, or a mechanic is able to tell you he know what he is doing. No fault to you, but we all have fallen victim to this. the mechanic needed to be more insistent on having the car timing corrected, especially, (don't take this the wrong way) since he was dealing with a female.
