Oil In Air Cleaner

[syfir]

Had to pull out the air box to put in a new horn, and oil was running out of the air cleaner(the part of the air intake after the filter). Is this normal? I have not seen this before.

Not exactly normal... Check/replace the PCV valve.

I just bought an '89 2 weeks ago and have the same problem. Mine is due to a blown head gasket. May not be your situation, but keep an eye out for milky colored oil or oil in your radiator.

Oil has no coolant and coolant has no oil in it. I thought of the PCV valve, I was under the impression if you can hear it rattle when you shake it, the valve is still good. Should I switch it out anyway?

[miami man]

switch it out because it is not that expensive

Both of my cars have been doing that ever since I've had them. My theory is valve stem seals.

EGO sensor is the oxygen sensor, in the exhaust manifold right?
