Answer

the problem you are having is that the PCV is clogged. The oil breather box is most likley your root cause, first make shure all your vaccum lines going to the intake are clear especially the one under the intake manifold. When this happens it builds alot of pressure inside your engine, which in-turn causes many oil leaks from random seals.
