hey guys. i have an alh tdi, running a bw s7 with pp520, and kerma tuning along with clutch and a bunch of other small things. lately under hard acceleration ive been getting some loud clicking comifg from the engine. it only makes the noise on acceleration and not on idle. its not a deep noise like rod knock but higher pitched so i am thinking its either lifter or cam. any input? im gonna take valve cover off this or next week to check them out but wanted to ask anyways. I know for sure its not axles, I've been through enough axles to know what those sound like. any ideas guys? i installed a new motor about a year ago and got it used, cam and lifters looked good so i never replaced them
