 2001 Mustang Cobra Valve Clicking Noise?
My 2001 Cobra has just started making a clicking noise from the drivers side valve area. I took it to my local dealer's service shop and they pulled a the valve cover off and inspected everything there. They concluded that nothing was wrong or worn. As they were putting it back together they put the valve cover back on without torque-ing it and the noise went away. They tightened it up and it came back. They disassembled it again and looked for rub or a conflict point inside the cover and didn't find anything. Ideas?
Thanks in advance for your responses. |
