So today I pull into my works parking lot and park my car and as soon as I turn the car of TONS of smoke start pouring out from under my hood. Im sick of things going wrong with this car so I basically said "welp, hope that doesnt catch on fire" and then went inside to work. When I got off, I took a look under there and saw oil on the back of my drivers side valve cover. I drove it home and took another look at it and after the car is hot, there was oil dripping, pretty constantly ,out of the vac. line fitting on the bottome of the upper intake. I have that vac. line fitting plug because I am not using it. Somehow oil got into the upper intake (pcv?) and maybe puddled up in the back of my intake. Any ideas what this could be? What should I check?
