Air pressure could be pushing the oil cap because of trapped air in the line. A mechanic could better diagnose the issue by inspecting the vehicle.
It injects oil into the fuel/air mix.
The pushing force of air is called air pressure.:)
Unscrew the oil cap on the valve cover on the right hand side of your air cleaner it attaches to the air cleaner. Al Cauchon

cap that covers the oil fill hole in engine
Removing the oil cap with the engine running causes a vacuum leak in the positive crankcase ventilation. This causes too much air to enter the cylinders at once, which results in a stalling engine.
Thermostat housing on 94 will be on top of the engine right side between air filter and oil cap, not oil dipstick
An oil filler cap is a metal that covers the hole where the oil is poured.
Oil filler cap cover the hole in the engine where engine oil is added
generally is next to the oil cap, it will be connected to the with other air intake house
there is a problem with the PCV (positive crankcase ventilation) system. this system circulates crankcase air and oil particles in the air back into crankcase by pushing them back somewhere back through the intake. there is probably a problem with the PCV valve stuck open allowing too much oil to pass through it subsequently collecting on your air filter.
The cap must be pushed down while turning it to the left. You can turn it without pushing down but it will only unlock and open if you are pushing down and turning at the same time.
