I bought my wife a 2000 mustang GT for x-mass clean as clean can be. I changed the oil just after I bought it. I now ve put 800miles on it and after about an hour she starts to tick on the right side I am worried. under the oil cap it is whits a little bit not much. on the dip stick none and I have changed the oil 2times since. if thier is a vary small leak in the motor could that cause my tick remember it takes about an hour at hwy spd. please help. I am trying to get the place I bought it from to pay but not much luck...
