Im working on a 1997 eclipse 2.0 engine and my ? is. What would cause a loud pinging noise similar to a rod knock in the upper manifold section of the motor. I think it might be a bent valve. I also pulled the pan off and checked all the lower components they seem to be fine. Then i pulled the head off and i do not see any visual metal on metal . So is it possible that the damage is in between the rocker and valve stem beating togeather and thats why im not seeing any visual damage?
