    How much is a little to much? quart, gallon. 1 quart won;t hurt, gallon, well this what happens. when the pistons go down there is no room for the air to go and compresses, this puts pressure on the oil in the sump, this oil or any oil won't compress so it pushes it out anywhere it's weak. If to much is in there it can push it out into pvc system and get sucked into the combustion chamber, if your lucky!!If it has it will take a while to clear and no doubt foul a plug or three, smoke black,run rough, it might even diesel (run on after you shut it off), You took it out,good,you probably didn't do any permenant damage.You could have blown pan gasket, oil filter or any number of seals if you left it in.Keep an eye on your oil consumption, check for leaks around valve covers, oil filter,the other option is tear it down.Another option is to wear a disguise and drive around the neighbor hood till it clears,HAHA
