My 2008 HHR 2.4 has just started having weird engine click when I turn key partially on. Then when I turn key off I get a click again.. 39699 miles on it..
Runs super, but this click sounds at top of engine, kinda in middle. Weird deal

Add on: only 1 click is heard when I turn key partially on.. And only 1 click when I turn it off..

Full of oil, etc..

 

Maybe the EVAP purge valve.

 

Would that throw a code ? This just started. No codes showing on dash

 

It is a solenoid, just clicking would not set a code.
Maybe one of the relays in the fuse box?

 

OK, sound is near valve cover.. Doesn't sound near fuse box, just very audible click

 

Anyone ?

 

Billy. How about a video ?

 

Turn key on but don’t start engine and hear one click .
Possible the VVT solenoid or fuel injector , or evap purge valve.
do you hear the click when you turn the key to start your car?

 

Remain alert, but don’t worry too much. Solenoids are electromechanical devices, and the mechical parts can vary and wear enough to cause changes in sound. Also, I can say from personal experience that one can become alarmed when one first notices a sound that has (probably) always been there.

Worry has an amplifying effect. Need a name for that.

Now I need to get in my 2011 and listen for noises. Will repot back. Maybe.

 

FMG- Hard to do by myself...

Blue- Yes & when turning off as well. I hear
it before I start mine, I let fuel pump run, then start. Same when I shut off, 1 click
