1997 Pontiac sunfire clicking sound when it warms up doesnt do it when it is first started only does it when the car warms up could it be an intake maiflod gasket?

Answer 1

I would think it could be an exhaust manifold leak. Look at the exhaust manifold for a bolt that is missing; then can vibrate loose( Some manifolds use gaskets-some don't). Also look where the exhaust manifold attaches to the exhaust pipe for leaks. Leaks will often leave a black or gray soot mark if they are leaking; and they usually leak once the motor warms up and parts expand. I hope this helps you. Mark
