i pulled oilpan, valve cover and transmission. i found nothing broken or loose.oil pan had only oil in it. it rattles at idle to about 2500rpm.noise speeds up with rpms. quiet under load and on down shifting.i am dumbfounded and out of ideas.
valves have normal lash. sounds like nuts n bolts in oil pan but not any.
