Does anyone know if Ve need timing change at 100000k??
I read somewhere it needs to go faster.
I'm guessing you mean the timing chain, no. Not usually. Mine is perfect at 100,000
miles, GM says is good for 170,000
miles.
Only reason I'm changing mine now is because I'll have the timing cover off and have to remove it to do stuff anyway.
105,000km service was uneventful.
