If you have oil pressure the lifters may be fouled with coolant tha entered the engine. could also be a filter broke up. fram filters have been reported to break under synthetic oil pressures.

If the oil is not with coolant in it add about 5 OZ of marvel mystey oil to the engine oil and see if it quiets down.... could be the engine was over rev-ed and carbon got into the lifters.
