    04 cold weather knock question

    My 04 wrx usually has a slight knock in cold temperatures when first started, from everything ive read this is somewhat common. The knock goes away after the engine gets to temperature. The strange part is, if i start the car and let it run for 5 minutes or so (while knocking), then shut it off and start it again, the knock is gone. I always run 93 octane fuel. Also I generally drive with the economy tune on my accesport. Has anyone experienced this?? Any info would help.

    Might be the timing belt tensioner.
    Life is like riding a bicycle in order to keep your balance you must keep moving.

    The timing belt tensioner is new. The shortblock is pretty new it only has 9k on it. And piston slap is pretty normal right?

    Yes, amongst the rather large list of "normal" Subaru noises.
