Default RE: knocking

ORIGINAL: DNeon
"With foot off gas, doesnt knock. Seems to happen after 30-40 minutes of driving (like grandma)." wat do you mean it seems to happen after 30-40 mins? it stops knockin after or it starts? like grandma? so if you were to drive at WOT all the time it wouldnt happen? anyway I would try higher octane just to see if its detonation. hopefully its nothin big. would you no where its comin from? bottom end or top? around wat cylinder? mite also b piston slap? could b a few things. good luck diagnosin that
Rolling with no acceleration or revving in netural, no knocking. It only occurs on acceleration, and only after i've been driving for some time (ie engine is hot).

thanks for the advice, guys.

there are SOOOO many things it COULD be, I would just take it to a mechanic, they do this everyday. This sounds like of of those deals where you could spend $1000 looking for a $25 problem...just take it to the professionals this time!
