help with weird noise!

[vande97]

well i have a knocking noise going on in the motor, it is NOT a tick tick noise either, it is more of a knock knock knock noise, it sounds like is coming right from the upper intake or atleast that is where i can here it the most, and i can hear it right around tappet covers, it is really weird, after the motor warms up it quiets down a little but you can still here it, expecially inside the car. I just cant figure it out. the motor only has about 1500 miles on it , i can only really here it good when it is at lower rpm. and ideas would be great!

thanks,

P.S if it was a bent rod wouldnt the motor shake like a BITC*??
mine is not shaking tho!
