Wikipedia: "Hydrolock (short for hydraulic lock) is the immobilization of an engine's pistons by a liquid (usually water, hence the prefix "hydro-"). Hydrolocking occurs when liquid fills a cylinder on the intake stroke and, due to the incompressibility of a liquid, makes the compression stroke impossible. This, in turn, prevents the entire engine from turning, and can cause significant engine damage if one attempts to forcibly turn over or start the engine. Typically, connecting rods will be bent, making the engine uneconomical to repair."

Well before engine 'locking' from a large amount of oil, excessive oil in the combustion chamber can cause premature ring failure and piston cracking from the excessive chamber pressures it can create.

I get that same engine bog down and I am positive that it is from excessive oil in the cylinders. Try making that turn in a higher gear. It works for me most of the time.
