You have to removed the exessive oil right away, it >> can ruin your engine. Actually - excess oil in the block can lead to all kinds of seal leak and bearing surface problems (not that I'm the OP on the above, but ask me how I know, as they say). Basically - the oil system on any engine is a careful balance between a known viscosity at a known pressure at a given volume of oil. Overfilling seriously stresses the rubber and bearing clearance calculations at cruising RPM. It seems to me most likely that whoever changed the oil didn't completely empty the block (say the car wasn't level) or just overfilled it (assuming all other things being equal). If the block was run cold and carrying a lot of oil in the galleries and head - you sometimes end up with a half litre in the system that doesn't drop. I actually run the car to fan start and pull the breather on changes now, just in case. The best thing to do it get a cheap turkey baster and a length of hose and pull out what you need to get it right. Measure it, make note of the mileage since the last change and see if it repeats. If it does, you probably need to look at rings or venting. If it doesn't - be more careful about oil changes down the road. It would be a long shot - but if your filter was somehow out of the circuit or your pump had failed completely - you could end up about 1/2 litre proud - but I've never heard of anyone managing to drive more than a few miles in either situation yet. Stunningly tough blocks though they be.
