Never had this happen in any car before. Been pushing the G4 hard, between work and mom in the hospital. Took off ramp to go home tonight and smelled hot oil. Said to myself "someone's burning oil", but not a beater in sight. Curious.
I get home and pop the hood. My oil fill cap had loosened and spun out, but luckily still in the engine compartment. Valve cover, alternator, abs unit and washer reservoir are covered in oil. Checked dipstick, looks like I lost around 1/2 quart. No lights, no codes, just the smell of hot oil.
I will be cranking that cap down extra tight from now. Just to be sure.
