Oil Filler Cap left off by Old Fool.

No fool like an old fool! Having topped up my oil, left the filling jug over the filling point to drain every last drop, and filler cap on bench. Removed jug, dropped bonnet and left home. After about 10 miles smell of hot oil and temperature gauge rising above 90, suddenly dawned on me that I'd forgotten to put the cap back on. Opened bonnet to find inevitable results, oil everywhere, but surprisingly oil level only a tad below the top mark on the dipstick. Felling like a dipstick myself, cleaned up as best I could and stuffed a duster into the filler point, and drove gently home to clean up and of course replace the cap!
All appears well, no warning messages, but occasionally (and this is two days after the incident) get random "beeps".
Can anyone please advise if my running without pressurised oil is likely to have caused damage?

Don't worry - I did the same thing a couple of years ago, no problems since.

You haven't been running without pressurised oil!

As Dave said, we've all done it at some point. More than once in my case. I used to have a MKII Escort that was just a bit tired. It used to develop so much crankcase pressure that the cap used to get pushed out. It usually landed on the exhaust manifold and melted and the car filled with a mixture of oil fumes and burning plastic fumes.

Could be a lot worse, this is the result of a missing oil cap at 2000 feet

The beeps your getting will refer to a misfire, remove the engine cover, coil rack and look down the holes, I bet #1 is swimming in it, clean out the oil, clean the coil packs and leads and rebuild, this should then stop all the beeping.

Silver GT 3.2 V6

Been there, done that - twice - on my old 145 cloverleaf. As has been said above, apart form the mess the only issue I had was a misfire caused by number one plug hole being full of oil. That and feeling a complete tw@t.......
