Question by lmf7000: my car makes a tapping noise when the engine is cold, but mostly on warm days?
When I start the car in a mildly warm afternoon, it make a noise that sounds like “tack-a-tack-a-tack-a-tack…”, and the noise remains only for about 60 seconds – approxamately until the digital temperature gauge in the car lights up its second segment (in this gauge, 1st segment means cold, 2nd segment means slightly warm, 3rd segment is operating temperature). The noise gets more rapid when I rev the engine slightly (although this car automatically revs the engine to 1500rpm when it’s cold, and the idling rpm gradually falls to 800rpm as the engine warms up). The tapping is quite fast, about the same frequency of the combustion noise of the engine. When I start the car on cold mornings the noise is not noticeable. Like I said, the noise is short-lived, it lasts until I take the car out of the garage and park it. What could be the problem? I tried opening the hood, but I couldn’t determine where the noise was coming from. It’s not THAT loud, but it can be heard inside the cabin when the windows are closed (and even when the windows are open)
The engine is a 1.4 litre petrol Ford Duratec and the car is a 2003 Ford Fusion (the European one, not the American one with the same name). The engine is completely stock, never been worked on by anyone other than the dealer, and I’ve just had it serviced about 1 month ago. It has 60,000km on the clock.
