Hi All The engine build of my ABF is coming together and i have just bought a new oil filter housing bracket, question is, does the ABF oil filter bracket require the oil relief check valve in the rear of the bracket part number 077103175B , part shown as number 6 in the below picture from ETKA The engine came without a bracket so i do not have anything to cross reference with, i do not want to fit the valve if it is not needed, also the valve seems very hard to find when doing a google search, so , what is it for and do i need it ???? Thanks
