Default 94 LS400 engine question

There is a rubber line which extends from the top of the valve cover (right side of engine next to oil dip stick etc.) and connects to the fuel injection unit (I think) on top of center of the engine. I'm getting a couple of drops of oil on the valve cover and thought it would be easy to replace.

So, anyone know the proper name of this rubber line? Would it be an easy fix (for me to do)?

Thanks

Without looking, I believe you are referring to a vacuum line that runs from the PCV valve to the intake plenum. If that's leaking oil then I'd wonder when the last time was that the PCV valve was changed. Get a OEM valve and grommet from the dealership for it if it hasn't been done recently (it's inexpensive), and if the tubing needs to be replaced as well, just get some standard tubing of the same diameter from AutoZone or an equivalent store and cut it to fit.
