when my car warms up i get a ticking sound off and on at idle or lower rpms. not at high. it sounds like is coming from the thermostat area. would a bad thermostat make this noise??
Could be an exhaust leak or some top-end noise, though
it helps to get a long screwdriver and put it up to your year. Use it like a stethoscope. Check around the headers and all around the valve covers. Where it's loud is where your noise is coming from.
