Metallic Knocking Sound In Engine????

sup 240 lovers, i have an sr20det motor and my car is running fine, only thing is that i have a metallic sound in my engine?? its not affecting my performance as far as i know, but it sounds like a lifter or rocker arm went out... anybody ever had this problem before and if so should i just spend the money to upgrade all my internals??

you may have a bent or burnt valve or a bas rocker arm that is causing a tapping sound. you should be able to tell if it coming from the top of the engine or the bottom.

thats a very open ended question (i added a "?" to the end since you didn't)
