The engine had an oil change just recently but there seems to be a pinging sound. my daughters froeid says it sounds like a valve. How do i know if I needa valve job and I understand that it could be the upper or lower valve. The upper is easier and the lower requires pulling the engine I hear. What is the cost and if I can't afford right now will I hurt the engine? Help
