sup guys…last week at school we installed AEM’s tru-times on my bros ls…well the install was easy and we got everything running ok…timing was right(but we still havent done the ignition timing)now heres the problem…we hear like a rattling noise kinda like a whurring,only between 2k 3k,before or after that rpm range and the rattle is gone…completely…we have been tryin to figure out what it is and we still cant figure it out…at first we figured maybe the hydraulic lash adjusters were bad and we checked them and they where horrible…fixed em got em nice and mint…the car definetly ran better but the fuckin noise is still there…and i swear its only between 2k and 3k…one of my other classmates had did them same thing with his civic ex and he noticed the same thing…as far as the setting on the sprockets we adjusted the intake to open 5 degrees sooner and left the exhaust alone…any comments and veiws would really help guys…thanks in advance…
please help me guys cmon!
