Hear a Tick Sound

[leftwing55]

I have a 02 GMC 5.3 with 57000km. At a idle i hear a ticking sound on the drivers side . Any Ideas ?

Ticking noises can be caused by a lot of things:

 

Spark plug wire

Serpentine idler

Exhaust leak

 

Because it's only at idle it might have something to do with lower oil pressure, like a lifter. If you haven't changed your plug wires yet 57K would be a good time - 65K if you weren't hearing a ticking noise.

 

Without hearing it I can only give you two cents.

 

 

Oops. Didn't see that it was 57000 KILOMETERS. I don't speak that lingo.

I have the same thing from inside the cab. It sounds like it is coming from the A/C under the dash on the drivers side. Any ideas?
