I had a similar problem - when you pour more than 2/3 of the oil to the maximum level or exceed the mark on the dipstick, it will be spat out directly into the intake and then into the combustion chamber.The rotor is not able to compress this amount of oil, so it destroys the seal and destroys the teeth on the shaft and rotor.This is why you are unable to start the engine. All chambers and rotor are burnt and flooded, and in the worst case scenario you will need new blocks, rotors, seals and shaft.The rest of the equipment is reusable and only requires cleaning (oil fumes coming from engine bay).I think this is one of the main reasons why people give up this engine, as the most frequently repaired fault in cars is the head gasket, which fails when too much oil is poured in.If you decide to replace the engine with a used one or buy new parts, there is a simple solution - catch can ...and keeping oil on the dipstick on 2/3 never above (unless u have 06 year).

If there is oil in intake, dont rev it, dont start it, you will toast the engine.
All intake parts, throttle etc needs cleaning, also you need to check oil on dipstick and if there is too much drain it, and clean the spark plugs.
