Please can you have a listen to this on YouTube it's the knocking noise my impreza makes, it is comin from the drivers side of the engine. When the car is cold there is no noise but as it warms up it appears and this is when it is at its loudest. Does any have any ideas what it is?
Many thanks
Kev

I doubt very much its big ends as the noise is there as you rev as well as when the engine slows.
Usually if its big ends rev to 3kish rpm and let off it will knock as the engine slows.
Thats more a put put put sound.

Any exhaust fumes coming out of the oil dip stick when you pull it out?
They are often there when the bottom end goes
I also had a water pump go on me about 10 years ago on an STI and boy did it sound like engine gone.
Sounds a bit more top end to me. But hard to tell from the vid.
Good luck with it

99.9% big end knock, ive heard a few! the reason why it sounds like its coming from the head is that the piston on the failed big end starts hitting the head.

I was told mine was big end bearing as well and it turned out to be the inlet cam gear fooked. This doesn't sound like mine but don't go forking out big money for what could be a silly fault IMO

Drop the oil into a clean container (though a cloth) and check for debris, once it's drained you can 'swab' the bottom on the sump through the drain hole also. If it is big end it's obvious from all the swarf.

Could be your Manifold Gasket or Exaust gasket.
Mine sounded like that when my Manifold Gasket was blowing, becareful not to burn your hand while checking though
