Noise in engine!
Had rings replaced a month or 2 ago. I have noticed a slight knocking noise in the engine when under load or accelerating. The noise is not there when reving the engine up in park. The noise does not go away when the car is warmed up either. Anybody here have ideas or suggestions? Please help....

Knocking could be fuel/ octane.
Change brands and see.
Else are you on a warranty? Bring it back after the fuel is ruled out.
If not look for loose bolts on the parts removed to re-ring....exhaust manifolds come to mind first. Accessory belt alignment. Lastly, pull the valve cover and check the rockers and head bolt torque for tightness.
