valve noise, gsr head, type r valve train
its a gsr head and type r valves and cams i think ( might just be gsr cams ) it also has double sprung valve springs on both sides ( all 16 are double ) its been make a little valve chattering sound ever since it was built, i had the valves adjusted and it still does it, its not really loud just loud enough to hear it at idle and low rpm's in the car, i have drove the car around 4k since it was built and it hasn't gotten louder or smoked, lost any power or anything.
should i just not worry about it, could it be that the type r valve springs could be making the noise cause they are stronger springs
