JFP, what seal leaks are affected by this? Had a o ring replaced on my AOS sometime ago, and wondering now if this was because it was overfilled.

For one, the RMS is much more prone to leak on a an overfilled engine, as is the front crank seal; and the AOS can actually "overload" (it is not designed to work in liquid oil, only oil vapor) and suck liquid oil into the intake, which can lead to a hydro lock.

Appreciate JFP.

To get about a quart out you can just unscrew the oil filter, dump the oil from the filter, and screw it back on. You'll need a pan under it or you'll have a mess. Then top back up as necessary a little at a time.
