96 Oil in air filter area or in air intake

There is a curtain in the valve cover which prevents most oil from being
blown out the breather. Any oil in mist form should stay in mist and be
captured by the air filter. I had a problem where someone replaced my
leaking valve cover gasket and *forgot* to reinstall the curtain. I was
blowing about a quart every 500 miles. The worst part was that it
*looked* like my rings were blown. You would step on it on the freeway,
oil would pump out the breather, go down the air heater hose and burn on
the exhaust manifold producing oil smoke. (Thomas Lee Grice)

This is often just from a stuck PCV valve. If it is, chances are it's
leaking down to the air filter (and the air intake pipe) from a black
hose which comes up to the air horn (2.2/2.5 engines).

In the 2.5 (probably 2.2 as well) engine, oil can get sucked into the
PCV system unless a baffle plate is installed. He did this and it
worked.
