Default Most likely the valve cover gaskets.

The 3.2 Ellesmere engine is notorious for a poor PVC system design. This causes pressure to build in the engine and the weakest link is the plastic valve covers. There is a tsb to modify the system to reduce oil leakage. The problem is worse in cold climates as the system plugs with ice.
