Check the easy things first like making sure the oil filter is on tight, then maybe check to see if it is coming out of the oil pan, if the bolts around the pan aren't loose, maybe you will just need a new gasket for the oil pan, then check to see if it's coming from the valve covers, which also may just need tightened or new gaskets,then check to see if it is a cracked head or block, which would effect how the vehicle runs. But if it runs ok and the oil pressure gauge is reading ok, it probably isn't the head or block.

Kia Carnival v6 2600 developed massive oil leak suddenly, near timing pulley, any suggestions?

There is a seal behind that pulley, pressure wash all the oil that has leaked out and run it and see if that seal is the source of the leak or it is coming from somewhere else. You need a completely clean engine to find an oil leak

Massive oil leak when drivivg.

I have the same problem with my 2002 grand am and its the oil sensor sending unit it has a straight stream coming out. It sits right above the starter and saturates the starter with oil. It looks you could be leaking oil in many different spots. It looks like an oxygen sensor and very easy to change. If the threads are frozen from heat spray it with wd40 and let it sit for a while before loosening the sensor. Some oil will come out, I suggest draining the oil and disconnecting the battery because the starter is so close to the sensor before doing this job. I hope this helps you.
