    coupe turbo knocking?

    hi, got an 03 standard coupe turbo 45k, changed oil for fully synthetic bout 1k ago, engine sounds like its knocking from 1.5k all through the rev range but not very loud (sort of thing only i can hear till i point it out to some one) only under load. i know the possibles turbo manifold and camshaft but havent checked them yet. i'm pretty sure its not bottom end as its not that sort of knocking. its slightly lower pitch than noisy lifters? anyone got any ideas or had this prob on their standard low milage car?

    thanks in advance..... cavvyt

    You sure its not pinking under load? Wrong range of plugs will cause this and cheap shite fuel. Use 99ron and prehaps put some redex through it.
