Is the clicking noise more of a tapping? Mustang drivechains are very loud, so there may be no problem. However, if the clicking you speak of sounds like a rock rattling in a spray paint can, you could have rod knock, which is NOT good. You may also haver a lifter tick (if it sounds like a clock ticking). Even the injectors make a very slight clicking noise which is completely normal. If your oil pressure is ok, then I don't think you have anything to worry about. Try to pinpoint where the sound is coming from.mustangman01 said:I know very little(But I am learning more) about my mustang.It is making a clicking noise under the middle of my car. I'm guessing it is my power steering pump,but am I right/wrong? can anyone help?
