it is difficult to diagnose a noise that one cannot hear.


please tell me, what information can I provide that would be helpful to you?

Customer: replied 3 years ago.

Faint thump almost like heart beat coming from engine only on tick over though comes and goes

Expert:  Steve replied 3 years ago.

this is probably nothing to worry about but it should be verified hands on


it could be an emissions pump cycling or a belt driving component failing


ultimately the noise will need to be traced using a stethoscope and possibly by removing the belts and running the car without them briefly
