The 570-11071 oil relief valve assembly replaces the earlier 570-11070 part number, please see image 2, as you will see there is only a slight difference to the external machining between the early and later version.

*Notes Regarding ST2 & ST3: The oil relief valve is only used on earlier ST2 & ST3 engines made before November 1978, later engines used a Self-Regulating Oil Pump which did not require this valve.
