didnt even look backed it out of trailer after buying from dealer put into garage and looked down and it was dripping oil. the dealer was there in 30 min with trailer and took it back for repair. i drove it less then 100 yards
It sounds like the screw for the vent line was to long and bottomed out in the hole. That's common and easily fixed with an extra washer. It doesn't take very much oil to make a BIG mess.
I wouldn't worry to much. Keep an eye on your intake box when you get it back to make sure your not pushing oil out the vent line by chance that maybe there is a problem with the engine.
