Ok, so reuse the half moon with the liberal rtv, especially where the broken part is. K.Do not remove what’s left of the oil pain gasket . It will never not leak it’s one piece with metal in it . You’re flirting with disaster doing that . If it were me I would keep that half moon piece that broke off above . Use a liberal amount of grey rtv “ the right stuff on the half moon , cover , pan where the gasket it and put it together.
Every HB I have ever done I’ve been able to install with a half inch ratchet and it presses down the crank nice and easy . If you wanted to impact it at the end once it’s seated sure but torque wrench is best
I have this JB weld ultimate black, is that good enough or go get the grey (where?)
