Not unless theres something wrong in #2 and 4 cylinders mechanically whereby
oil is entering the cylinder and leaving a dark greasy deposit or there is a
vacuum leak in the intake whereby they could run lean and hot and not leave
the light tan deposit normally found in a good running motor.
I feel confident for the amount of time I spent massaging that shortblock
together that it is perfect and there won't be a mechanical problem....Bob
