I second this. Remove and check all hoses going out of flame trap. If in doubt - replace. They may not be clogged but when old, they get hard and will inevitably clog. Remove and clean brass nipple in intake manifold that small hose from flame trap inserts into.

After replacing flame trap, oil cap and valve cover gasket; my car still leaked oil through cap, back of valve cover, front and rear seals. Took me two tries, but I finally discovered a clog in the small hose from trap to manifold. Cleaned nipple, replaced small hose (.60) and the hose between the flame trap and the breather box (oil separator). Voila, 250K and no oil leaks!! Well, maybe an occasional drip from the oil cap....

FWIW - I was resigned to the fact that I was going to have to go after the damn breather box. But persistence paid off in this case. Best part of all was that the rear main seal leak dried up!!
