BlueZ31 Posted June 27, 2008 Share Posted June 27, 2008 For some reason or another the intake rocker arms on my passenger side VG30e motor go for about a month or two and then slowly start tapping louder and faster, and i honestly dont know what could be causing it since ive always maintained a good oil change schedule and use lucas oil stabilizer at every change... Awhile back though one of the rockers became seized with a dark greyish sludge so badly that it couldnt be move by hand at all, and all i can think of is that maybe it was seized so badly that the lifter jammed and scored the cam lobe causing it to lift unevenly possibly leaving a gap between the tip of the rocker and the lifter itself that cant be adjusted, but it still doesnt explain why it seized in the first place or why its so damn noisy..not to mention why my friends z31 with a fresh set of heads,cams and lifters taps upon start up too..maybe to much strain on the valvetrain or a flaw in the stock oiling system!? the heads are non-w-code. any ideas or solutions would be greatly appreciated!

Worn out parts make noise. and so do parts that are meant to move but are stuck. fix that first. fresh new parts with cams makes noise due to the added lifter load.
