Before you tear it apart and get new seals - you might want to try tightening the bolts that hold the filter housing to the block. It could be that the seal is leaking because of a less-than-torqued bolt.
Otherwise, it doesn't look too hard to unbolt and repair. Just remember to lube the new seal before you put it back together.

There are only 3 bolts to that housing. But the back one seem to be under the manifold or is the wrong one? If is its going a pain one.
