Lately it has been way under the freezing point here. For like the first 5 min of driving if I dont have time to let it warm up the STi sounds like cylinder head knock while driving untill it is warm, then the problem goes away, or if it is over 3000 rpm. When I let the car warm up it isnt there. I have the correct weight oil in it too. My 2003 WRX never made this sound. Is this just some cold motor noise I hear or what?

i dun have that problem. when i dont have the 5mins to warm it up, i just drive verrry verry slowly...very minimal throttle =). try driving like that for about 3 miles, then see how it is.

 

It does it in under 5 mph and up. I have to usually drive through some big parking lots, pretty slowly.

my wrx does that ticking until warm. I dont drive it until it stops ticking. oh sorry, my wrx DID that, until I traded it in last night for a shiny sti!

 

The cold-start valve tapping sound is normal for a Subaru. Make a note: Never try to sell a used Subaru to someone when it's cold out! If they aren't already aware of it, they will never believe you that the sound is normal.

 

good to know

 

Thank you, my gut feeling isnt flipin out anymore.
