haha yep followed them .. pretty easy to do...
the screw was in there tightly, with plumbers tape wrapped around... i had to force the thing in, so it was very tight and secure.
it had a nice flutter on low spool, but once i stomped it abit and let off it had a flutter mixed with the pssht at the same time... kinda sounded like the bov was dying
and i do have a r32 rb20det, so its not a NICS engine problem
maybe the vale has a weak spring in it... i dunno i just took the screw out
