Sounds like an VW or BMW from the 80s then goes away after a minute.

Not.much on this on the internet on this... 1 guy mentions this and his car had 9k. Everyone suggests this normal.

Confirm this?

Possible solution?

Thanks!

(edit: I see the old threads now that I made this it suggest them.. (ok normal) But why truely does it do this? Without guessing anyone know? And can it be altered to not do this?)

 

gonna have to describe the sound

 

If the sound you are talking about only happens on a cold start, it is normal.

On a cold start, the cam timing is changed to reduce the time it takes for the catalytic converter "light up" (heat up) and start to function.
This is similar to what a secondary air pump does on BMW and VWs.

 

I don't have any weird noises on startup so I still don't get it lol

 

Good answer, Sonic.

The engine sounds very crude and mechanical before it steps down and starts to warm up, but it's mostly something you only notice if you park in a garage.

OP, every new G owner goes through this. No worries.

 

Are we talking about the subtle clicking-like noise from engine bay?

 

You bumped a dead thread to ask for details, then dismissed the topic because you don't hear anything untoward with your own car as far as you know, but then brought up a clicking noise anyway.

dude...

The OP's concern has been discussed ad nauseum over the last decade. Sonic nailed it. And we're done here.
