I broke 2 off have 3 left and also dinged the oil pump housing while trying to slide the snap ring a bit. JB weld will save my *** or do I need a new housing or worse a new timing cover?

Trying to remove the mother of all snap rings from the cast aluminum housing I managed to break two now I have the two top ones and bottom one left can I JB Weld this thing so it will not leak oil. do I need a new timing cover ?etc. :cry: I also chipped the housing while I was trying to move...
