The Chrysler hemi performance engines are notorious for making slight tapping or ticking noises. Tapping and ticking noises can be caused by various problems in the motor, however these noises are most likely caused by a lack of lubrication, and may be a sign of a more significant problem. If your hemi has begun making a ticking noise or the noise has increased, you should take the vehicle to a certified professional mechanic so that the cause of the ticking can be professionally diagnosed and repaired.

What Makes Your Hemi Tick

Ticking sounds in an engine are commonly caused by a lack of lubrication. Lubricants such as oil and fuel flow between metallic components and provide cushioning so that the parts do not tap against one another.
