Black inside of IM - 83 5kt

[JShadzi at aol.com]

Due to the crankcase breather system, oil is all over the inside of you 
intake system, close to 20 years of this oil heating and burning in the 
inside of you IM has resulted in this.  

It is not a problem, compeltely normal, I usually use some sanding rolls to 
clean up the inside of the IM, or you can just leave it.

 Is there a problem on my engine?  I noticed that the inside of the Intake
 Manifold (IM) is all black.  I owuld think that since just air is passing
 through, there should not be any discoloration.  The black is throughout
 the large section of the IM, and also in the throttle body area.  Thanks,
