 I recently rebuilt mine and found this video. This guy has the early style oil pressure relief setup with fewer parts, but it's all relatively the same.

I used a little aviation sealant on the o-ring on the cap that holds the oil pressure relief setup. That seems to seep a little over time, and it has worked as it's bone dry after a few hundred miles. As with everything else 907 the tolerance on that small o-ring is very tight, I tried using a replacement out of a buna-n kit I had and it kept splitting the O-ring. Ended up ordering the OEM part.

Lots of assembly lube on re-install is always a good idea. Helps to prime it a bit too by pouring some oil in the filter.

Another good idea is to replace the round keeper clip - that silly little clip actually holds the entire oil system together. Mine was bowed badly and the distributor kept popping off of it as the entire shaft slid forward.
