my 94 zj 5.2 w 260k ran the same as you discribed. thats why im kind of lost as to what the dealio is with this other one. its not oil level and does not consume oil. fan clutch is good to go. the tornado sounding sound is when you give it a little extra gas. like 3krpm and above. thats waht leads me to assume plenum is bad.
