WRX 2004 no engine mods totally standard, serviced, oil always checked loved like a child and last night it started to rattle under load in the centre of the engine. Tickover is quiet as a mouse but rev it and you get a nasty noise
Hoping its covered under subaru warranty but if it isnt I might need some help and advice as to where to go for fixing

 

if its standard cant see it being anything major on a car that age

well hopefully

 

Heat sheild..?
