Hi mate - so think we have ruled out rod knock thankfully… discovered two sections of centre exhaust cut out (squares cut out) not sure why but mechanic thinks this may be the issue on cold starting I’ll be sure to confirm
Hello members - i recently purchased my WRX 2.5.. 2006, does this happen to anyone else car starts fine - but after 2,3 seconds she develops this low knock noise then goes away after 10 seconds or so.. should I be worried - she’s the correct oil level etc..
