my husbands GMC truck has an occasional ticking noise coming from the engine area. The noise happens when you crank up although it doesn’t always happen. It will sometimes go several weeks without ticking/clicking. When it does start, the sound usually goes away after the truck “warms up” for a minute. The ticking/clicking does not change pattern when you accelerate. The mechanic said it just needed an oil change, but my husband has made sure to check the oil.
Thank you for any help you can provide!
