The plenum is what people tend to call the upper intake, it doesn't even have coolant passages. Check for signs of coolant in the oil, if there is it's probably head gaskets, which is rare on these. If not there, check all over for signs of leaking, if you don't see any you'll probably want to get it pressure tested to track it down.
