Cleaned it up really good, then used liberal amounts of RTV sealant to seal the gasket in place.
sounds like someone is looking for more trouble there, especially if the gasket was a rubber type.
The upper "A" arm ball links are bad and need replaced,
Ball JOINTS.... many of which CAN be replaced without changing the whole control arm.... despite what ford says. look to MOOG suspension parts.
Regarding the oil gasket:
1) it is the rubber type
2) this marks the SECOND time that thing has squished out from between the block and oil pan.
It is hopefully secured both top and bottom now. I wonder about pressure buildup, and will be replacing the PCV valve, but there is also a breather port at the oil fill cap on the valve covers, so it seems unlikely that pressure buildup would cause the gasket to blow out.
