Mystery Oil Leak
pulled the 430 out today and i notice a small bit of oil on the garage floor. JAW DROPS and now my football sunday is ruined by curiosity and anger! Prior to me noticing this engine bay has always been clean along with the under carriage.
Car has not been driven in about a week, looked inside engine bay and notice oil on the bottom sitting on the plastic floor board thingy (sorry, dont know what it is) Engine bay is still clean besides the bottom portion. Undercarriage now has some oil spray from when i drove it today.
Is it possible to just get an oil leak overnight from a car that is just sitting?
I thought maybe from when i chnaged the tires and lifted the car it somehow twisted the car/engine?? (wild idea but im so confused)

The most common oil leaks are from the vent covers on the valve covers, and form the little oil pressure test port on the front driver's side of the engine. Both easy re-seals.
Have you had your oil changed recently? Sometimes the wrong o-ring on the filter cap is used, causing a leak down the filter housing.
