after the car is fully warmed up and I turn off the engine with windows down in my garage so I can hear side wall reflections I hear this "clank" when I turn the key to shut the engine off. It sound metallic. Is this normal?

 

You mean that sound that every car makes?

 

Sounds like mine when I turn it off. It differs from the sound from a piston engine turning off, but I've never been alarmed by it and have assumed that it's normal.

 

not quite. Its like the enging stops IMMEDIATELY with a clank. Not like a piston engine. Its a definate noticable sound.

 

I didn't figue anything was wrong or I would have had side effects buy now. I chaulked it up to normal, but I couldn't find any posts specific about this so I figured I'd ask to be safe. :D

 

It is a strange sound, as if something is dropping out from under the hood.

 

It's nothing to worry about. I had mine checked out, along with about 7 other cars on the lot. I wish I remembered what they told me it was from-something about a valve opening and shutting? Sorry.

 

its either the s-dais or the throttle body plate checking its position. just one of the many tests this car does when you shut it off. take off the intake tube and watch the throttle body as someone cycles your key.

 

If you listen carefully, you can also hear the auto levelers moving.

 

yup

definitely in the intake system. Usually only hear it if the windows are open.

 

It could also be the flux capacitor? :D Sorry...I couldn't help myself!!
