i dunno, but when i turn my car off after returning home from work... work clicks..... it clicks like every 10 seconds, and then as the car cools down, the clicks go down to about 15-20 seconds intervals... i can hear it, when i lean under the car.... but what the heck is this noise, im almost positive its coming from the exhaust but could be wrong.... btw its a 94 accord lx.... thanx in advacne....

when metal's temperature rises... nevermind...

do you go to school?

 

What lunarone was going to say was, metal expands when heated, contracts when cooled. The ticking you hear is the exhaust piping cooling/contracting.

 

well i noticed too, that it does it when driving tooo....

EDIT: for example, when idling in a drive way...

 

Perhaps it is still the heat thing. Maybe your engine/exhaust is hotter when you are driving and for the few seconds that you idle, your exhaust could be cooling...maybe

 

Is the exhaust new? If so, it could be binding up at a joint somewhere.

 

mine does that bugged the hell out of me tell i realized it was what lunarone and philadd said but it is pritty loud but bothing to be woried about
