Last night i pulled off the valve cover to my d16y8( to paint it ) and first realized a whitish paste on the bottom of the Valve cover and then was a little confused as to what it was, then i looked at a crossbar thing on my head and it had ysk 3b printed on it, i bought the car from a dealership and am wondering if this is a stock valvetrain component or may i have a rebuilt motor?


P.S. sorry for the noob question

thanks
