It only gets worse after about 5000 rpm... It's a weird one haha. Bye guys there's a group on Facebook called subaru imprezas owners club or sioc, it's a great group, well worth having a look on

Hi guys bought this 2005 cheap as a non runner due to the seller saying the engine was blown... Now the engine runs absolutely fine when cold but when it heated up and is revved past 4000rpm there is a slight knocking noise... I thought this was quite strange as usually knocking can be heard from startup. I've had a look on YouTube and it could be the cambelt tensioner but could anyone give me some ideas please? Thanks a lot
