yea i think it is kinda gray. but there are no bent rods because i changed all the rod bearings and there is no knock but still the smoke and when the engine is warmed up it has 0-5 psi oil. also the engine is still missing as well. i think this is all due to some shot rings on one of the cylinders i think number 7 because in the dark that header glows red. well thnx for the help guys
