Chevy colbalt engine chater or ticking.

timing chain could have jumped timing if you hear timing chain noise.

It could be the starter,try have some do a load test on the battery to confirm its not the battery. Clean up the battery terminal connection to the battery post. Might be just a bad connection because of corrision.

Need Flywheel Machined and a New Clutch Disc

Could just be positrac differential.
Mine positively hops into the air when I take a corner too tight while accelerating.
As long as fluid level is good, I would not worry about it. I think it is normal.
Cars don't have this feature.

no, its not the transmisshion,,,, its the cluch release bearing worn out,
every time you press on the cluch it screems or chaters, yes?
you just need to fit a new cluch, as its realy not worth the effort in just replacing the bearing only to have the rest of the cluch go in 6 months
that would be mad ness and pricy

Sounds like the flex plate that is between engine and trans may be cracked Have verified by inspection

Probably have to replace if worn, but to confirm, what engine are we talking here?

check all vacume lines some will cause your motor to act 180 out and also if valves are chatering get a feeler gauge and set them to 12 if to much drop down one..

does it go tick tick tick tick and when it warms up it stops or goes quiet?
its your lifters not getting enough oil
when u change your oil it will stop till that oil gets worn out
you will have to replace the lifters or it can also be a slack oil pump not pumping oil around the engine like it should
