so im puzzled....

i pulled my head the other day, to find a black oil/tarry substance on 3 of the four pistons, the engine has less than 1k on it since the complete overhaul,

the one piston that didnt have the oily substance on it looked brand spanking new!

any ideas what might of caused the oily substance?
