There's also the balance shaft cover in that general area that could leak as well. It's the funny shaped plate on the side of the block under the intake manifold. It has a gasket and two bolt holes. I put a couple of o-rings under the bolts just because...

Be careful with that one. The two bolts are small. I rang one off installing the cover and it didn't seem like I was torquing much at all. Could have been a bad bolt or could have been that it was near the end of the day and I was tired/not paying attention.

Fortunately, the engine was still on the stand. So, I removed the cover, got the broken bolt out and quit for the evening. Went back the next morning fresh and reinstalled to factory torque without incident.
