Nothing I can think of under the intake. It may be a valve cover gasket.
Remove intake and inspect block, it could be cracked, or valve cover is cracked.
This oil pump on the Toyota puts out A LOT of pressure. It is possible the oil pressure relief valve on the oil pump is stuck, creating EXCESSIVE pressure.
Other possibility is head gasket, broken head bolt.
