For some bizarre reason, I enjoy working on the breather box, flame trap system. I don't have a huge amount of technical skill, and because it is a pretty straight forward system, I feel like I sort of get the point.

Just take all the hoses off and clean or replace them. Take the breather box off and clean or replace it. (I always just replace...you can get one for $30 or so)
Follow the FAQ's as Uncle Olaf explained or use Bentley and enjoy the process.

The first time I did it many years ago it turned a car that would barely crank and run into one that ran like a brand new automobile. That has happened to me more than once. Of course, that doesn't happen every time, but it is a good place to start.

If you clean and free up the system, it may or may not stop your oil leaks. Either way, if you have been leaking a long time, expect to drip for a while longer until all the accumulated oil heats up and drips off. Again, if the damage has already been done, you'll have to replace seals, etc. Sounds like you have done some of that already.

In my current car, after I replaced the breather box and cleaned all the flame trap system, I went from a leak that was about 1/2 to 3/4 qt of oil every two weeks---enough to really mess up a garage---to just a few drops every two weeks. I can live with that for a while. Let us know what solves your problem.
