Only thing I can think of is rings or the oil isn't returning from the valve cover and pooling there going down the valve guide,, or the oil is way overfilled,or the head gasket isn't seated properly better call s b t and ask them it is under warranty and they have tec support for their engines 1 877 330 0231
