The manifold itself doesn't leak, but the gasket that seals the intake manifold to the cylinder heads and the engine block does. The gasket is subjected to alot of thermal expansion and contraction and over time, fails to retain the sealing capabilities needed to prevent leaks. One note. If you have a large oil leak, check the oil pump drive oring for being the problem, not the intake. The oring tends to dry out and not seal. Typically, it will leak alot of oil when the engine is cold, but slow down once warm.
