Over the past few weeks my m20b27 has developed a noise in all gears when the rpms go past 3500 rpm. Its kind of a high pitched squeal. Any ideas on what this could be? I haven't noticed any vibrations or anything else.

Belts actually have a date stamp on them although that won't tell you if they sat on a shelf for a decade. If they have any signs of cracking or wear change them otherwise I'd make sure they are tight and try some belt dressing to see if that fixes it...then change them :)Seat Shocks....I have passed the baton to John Christy from Ninestitch.
