Alright, just did my timing belt change about a month ago...she's been behavin very well. Last weekend, had some extremely spirited drives around country roads...was hammering her and keeping revs at 5-6000 rpm throughout...FUN!!
I've always had a slight rattle comin from the engine bay, which I concluded, was due to my cracked up heat shield. This didnt really bother me.
Today, I rammed her to 6200 rpm on the motorway, and noticed, beyond 5000rpm in most gears, the engine note changed from a rorty sound (which is usual) to a loudish rattle (which didnt sound too comforting)!!!
No loss in power and performance was experienced...just the engine note which seemed to have gone south. Its a distinguishable rattling noise.
