My wallstar boiler ran out of oil and now I have had a delivery, does the oil need bleeding to fire up the boiler?

The cream is an oil/water emulsion, you still have water in the bottom of the oil tank, this need to be pumped out as even the smallest amount drawn into the line will create the froth you describe, damage the oil pump and nozzle and cause very poor combustion and lock outs. You need to find out how water is entering your storage tank
