Shouldnt it create that noise even in neutral?

Anyway i will change the TOB, new clutch disc, new pressure plate and an lw flywheel next month. Gonna investigate the heatshield and tap it a little to see if it is loose somehow.

The noise seems to be related from harmonics since its only occurring at certain RPM and load ranges. This could be causing a heat shield, unloaded gears in gear box or something else (bolted to the subframes or driveline) to make the noise you are hearing.

FYI...If you plan to install a LW flywheel then this will most likely increase the presence of any harmonic noise coming from the drivetrain. So your annoying noise may become more annoying, stay the same or may entirely go away(self correcting automotive repair SCAR ) SCARs are my favorite !!
