ticking noise

[LilRhodyXJ]

when my jeep is idling i can hear a small ticking noise... it sounds just like what ud picture a tick sounding like and its about this fast
say this normal speed... tick tick tick tick tick....it never gets faster even when u rev it and it never gets louder... it hought it was an exhaust leak but ive had this noise for well over three months and it would have gottin louder by now if it was that right? so my question is what else could it be? how could i figure it out?

Try to localize the sound by using a length of heater hose as a stethoscope with one end against your ear and the other looking for the sound.

There's a purge valve in the engine bay, against the firewall near the top, on the passenger side. It should be mounted on a bracket with a rubber isolator to minimize noise. The sucker can really put out the annoying ticks you describe.....

could it be a bad relay?

Sounds like piston slap. Does it sound like a Diesel??

[outlander]

Pay particular attention to the injectors while using the mechanics steth. that dr. dyno suggested.This was the source of my tick.They can be quite loud.

Could be a lifter making the noise too.

if it was engine related would it not get faster when you rev it?

never gets louder, never gets faster, and its really suttle..like most people cant hear it untill i tell them and they listen for a little while.. its just constant but really small..ill try that steth. maybe i can find it...

Your most likely culprit.

thanks ivan i'll take a look... the noise could possibly coming from the middle of the engine... i put my ear near the valve cover and it seems like tis there but hard to tell...with the hood closed u can only hear it if u stand near the back fo the wheel wells with the engine open it seems to be in the middle of a little off to the passengers side, if ur parked at lets say dunkin donuts waitin for a coffee u cna deffintly hear the ticking noises echoing off the walls...so its there but its subtle....could it be a cracked header or mabe a gasket or something....

thanks for all ur help i'll be taking a look at the purge valve tomorrw mourning
