Is the 3000 rpm buzz bad for the engine?

[heymanwatchthis]

Hello everyone, my name is Gary and I am a new member here.

My 2001 986S has a slight buzz at 3,000 rpm's that appears to be relatively common and is similar to that described by others.

I have read much about it using search and see there seems to be some debate about the source of this buzz - exhaust, cam profiles changing, boxer engine personality, etc etc.

What I am trying to figure out is if it is a bad thing.

Does the 3,000 rpm buzz mean there is something wrong with the engine?

Should I avoid conditions that create this buzz, i.e. is it bad for the car? Or just not worry about it.

Thanks everybody!

Gary
