I hear a metallic tinkering in the morning when I start my car. When I pop the hood, and listen, it seems to be coming from the underside of the engine, pretty close to the center. It's pretty rhythmic and accelerates when I give the engine some juice. Once theengine is warmed up the tinkering goes away, and during the summer months, it's completely absent.

I noticed it last winter as well. I'm assuming it's just a temperature related thing (and nothing to really worry about), butif any of you can pinpoint it for me it'd put my mind at ease.

Thanks again for the input.

 

my injectors make a lot of noise when cold, that may be a possibility

 

mine does the same too... at least yours starts all the time in cold i swear my car thinks its a diesel lol

 

my pistons slap like hell when it's cold... I hate it. and my belts also make abit of noise, they dont screech, more like a chirp

 

Mine too... but funny thing, I swear I didn't do it last year.
Sounds to me like rocker arm/valve adjustment clacking..untill it gets warm
Used to adjust those things frequently on the old VW bugs I used to play with.

 

mine does that too, it doesnt bugger off untill the car is completely warmed up, i can stand the sound

 

well i guess im not alone. mine does it too.

but i hate the sound it makes when there in ice on the lower portion of the back window, just above the trunk. it makes a screaching noise till i get out and break it off. drives me crazy.

 

its valve tap......

the engine is cold and the oil is really thin so it casues the the tapping nosie. Its not your injectors either.

 

I have the same problem, as i can see everyone does too......i just turn up the music and WALA.......its gone!!!

 

Same here
