Just to clarify. There is a cap that is bolted (only 2 bolts) to the engine block just above the engine oil filter. If so this is capped off and is designed for an auxiliary engine oil cooler (if equipped). I've seen a lot of these leak (and engine oil pan gaskets) make sure you order the gasket without the engine oil cooler gasket because the gaskets are different between the two.
The reason it leaks with the engine running is because this cap is just after engine oil pump. Hope this is what your talking about.
