Exhaust Color
by Jim Worley » Mon Nov 19, 2012 5:25 am
What color should my exhaust stains be? Left side is mostly gray to white. Right side is much darker. Is that because the breather is on the R side and and probably puts a little oily mist into the slipstream from time to time? Is the fact that they are different a cause for any concern?
61 250, converted to IO-
540, Eagle XP cowl with dual exhaust.

You will probably find a cyl on the right side that is burning more oil. A quick check of the lower plugs in cyl 1,3,5 should tell you if this is the case. If you have a very wet cyl, then it is time to explore why. If you still have good compression, and satisfactory oil consumption, then continue flying.
