Q: Can a timing chain be reset 2008 Chevrolet HHR

Hi there - I think your question has to do with the engine "jumping time" - that is the timing chain has jumped a cog or three on one of the sprockets, and engine management realizes one or both camshafts are way out of time (relative to the crankshaft). Yes, you can re-time the cams to the crankshaft. BUT - the question you have to ask is "Why did it jump time in the first place, and has that been corrected?". If the timing chain stretched, or the tensioner went weak - and these have been replaced - all well and good. But if you are just re-timing things without fixing anything - odds are the next "event" will be much more expensive. If there is any doubt, I recommend a timing chain replacement service performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, replace all the worn bits in the timing chain system, and get you back on your way with confidence.
