Is there a o-ring or gasket between the oil filter housing on jeep grand Cherokee Laredo 4.0 motor where meets block?

No, there isn't a traditional O-ring or gasket between the oil filter housing and the engine block on a Jeep Grand Cherokee Laredo with the 4.0L engine. The housing itself is typically sealed with a rubber gasket that's integrated into the housing itself. This gasket is usually pressed or molded into the housing's mating surface. It's not a separate piece that you'd install like a traditional O-ring or gasket. You'll replace the entire oil filter housing if this gasket is damaged.
