Subaru mechanic just told me that my timing belt tensioner needs replacing along with one "unbalanced" main pulley(??? due to bad tensioner may be? Personal opinion...).
I have some slight rattling / knocking engine noise from my 8 months old WRX03 the first few minutes on idle that dissapears when warm or high revs and believe me I am glad it isn't something more serious as piston slap etc but we'll see when the parts are here for sure...

The belt tensioner can sound very "metallicky knock" from cold start, often virtually dissappearing when warm or high revs, so make sure not mistaken for crank knock.
The tensioner sits on the nearside of the timing cover, so you can always check to see if the noise does seem "louder" at this point. will help with simple location diagnosis.
if the noise seems more "central" to the engine, well, sorry, it does sound more like crankshaft.
Incidentally, crankshaft pullies only "normally £ fail if the centre rubber dampers has split,otherwise no problems encountered.

I visited another Subaru service just for diagnosis and they told me that ALL crankshaft pulleys (visible external) have a slight movement as mine (they have rubber inside), what to believe now?
And where are the rubber dambers inside pulley?

SCOOBYSLUT - Is this noise something like a "tic tic tic", high pitched, only on cold start? That's something I have from a long time ago, but no subaru dealer mentioned about it when I took the car for regular service...
This worries me, as I went through bad experiences with the timing belt with the ECOTEC Opel tigra engine...

thought I had allready diagnosed this over the phone..
Sounded like rods / crank..
with no oil / holes then more likely to be the crank.
