I have been following the threads re loose engne mounts on 172s.. and to my dissapointment, the left hand (looking from the front) engine mounting on my 172 doent seem too mounting
can you - if you hold the plenum area and rock the engine back n forth - see and hear movement in the main mounting.. mine sorta slops about 3 mm back n forth with a slight clicking sound.. nothing appear broke, but it doesnt seem happy.. if this is std, them I think it might need further investigation..
