Hello I own a 1999 sterling l75 dump truck It is loosing 1 quart of oil back into the fuel. I was told it was a crack head, but it does not make any sense me because a cracked head usually mixes oil and water, It is a cat 3126 Has any one had any problems like this. I believe it is the injectors any one?????
