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.
Yes, an oil cap should be air-tight to prevent contaminants, moisture, and dirt from entering the oil reservoir, which can degrade oil quality and engine performance. An air-tight seal also helps maintain proper pressure within the system, preventing oil leaks and ensuring optimal lubrication. Additionally, a secure oil cap contributes to overall engine efficiency and longevity.
When you squeeze a bottle, the pressure inside the bottle increases, pushing the air out. This causes the air pressure underneath the pen cap to decrease, creating a pressure difference with the water around it. The higher pressure of the water pushes the pen cap down, causing it to sink.
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

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.
Oil filler cap cover the hole in the engine where engine oil is added
An oil filler cap is a metal that covers the hole where the oil is poured.
Thermostat housing on 94 will be on top of the engine right side between air filter and oil cap, not oil dipstick
The chain under the oil cap is typically referred to as the "oil cap chain" or "oil fill cap chain." This chain connects the oil cap to the engine or valve cover, preventing the cap from being lost or dropped during maintenance. It's a small but important feature that helps maintain engine cleanliness and safety.
