2003 WRX STI Engine rattle

Hi,
I am looking to buy a bugeye wrx sti and have been to look at one today.
I like it and its within budget the only issue is an engine rattle/knock that it has.

It sounds exactly the same as this youtube video...
What is that sound?



Any ideas what it is/could be?

Any help is appreciated thanks!

Re: 2003 WRX STI Engine rattle

Hi mate.

Is it doing it when cold or also when warm? If only when cold then it's probably piston slap which is normal on Subaru engines. If it is doing it all the time then could be a sign of something more sinister. Subaru engines are noisy at the best of times anyway so often difficult to tell. Mine sounds like a bag of spanners when started from cold, especially in the winter.
