Does an exhaust leak make a ticking sound?
Exhaust leaks are distinct and easily checked. As the vehicle warms up, these leaks get louder. As the metal expands, exhaust manifold cracks and flanges expand, allowing more exhaust gases to escape. They make a sputtering sound as opposed to a lifter with a ticking sound.
Why do I hear a ticking sound out of my pipes exhaust?
The noticeable sound of ticking, clicking or knocking is often caused by a metallic tick like something inside the motor is hitting a metal stick against one of the components. As the engine’s RPM increases, the ticking or knocking sound will commonly increase as well.
How can you tell the difference between an exhaust leak and a lifter tick?
Registered. A lifter tick is very different from an exhaust leak. The exhaust leak will have a sharper sound (compressed gasses pushing their way through a tiny crack) and the lifter will have a more mechanical sound (metal pushrod striking metal rocker arm or rocker arm striking top of valve).

If it’s an oiling issue, check the engine oil level. If it’s low, add oil until it is full and see if the ticking noise goes away. If the oil pressure is the source, you might have to contact a professional mechanic to inspect your oil pump or components that supply oil pressure inside your motor.
How to tell the difference between an exhaust leak and a leak?
Locate the noise. At times it is difficult to zero-in on the noise, especially since sound will carry through metal. It helps to twist an old newspaper into a cone and listen. The general area of the sound can then be more easily located. Isolate the sound. A mechanic’s stethoscope will help pin-point the noise; however, it’s not foolproof.
