Don't think it's anything to do with the belt. Imprezas are prone to piston slap when cold

it is when the engine isn't up to temp when it gets a bootfull,iirc the newage impreza's run with hydraulic tappets, so will be a tad noisey until the oil is up to temp n pressure..

Scoobies do make some funny noises, generally if those noises go away after she's warmed up she's just fine ...

just some ideas,could it be the injectors you can hear,maybe a sticky valve,is it running aftermarket headers?if so you could be hearing the cylinders firing through them,blocked or slow running oilway..

is the motor down on power/performance?? if so get it to a rolling diagnostic center..

Mine taps when cold, but goes away when it is warm. I could do with putting a better quality oil in it, but havent had the time. Also, I get a little tapping noise from the injectors. Again, nothing to worry about. Just remember to warm the engine up BEFORE giving it beans. It only takes a couple of miles driving, but until then keep the revs under 3k, then.......floor it and enjoy!!! Look after your Scooby and it will be fine!!!
