Ok so it is hydro locked. I took the CCV and throttle body off. Throttle body was full of oil, so a assuming intake manifold and cylinders are full of oil. How can I clean them up?

For cylinders, I will take spark plugs out and crank the engine to spew the oil out of the cylinders. Is this enough?

How to clean the intake?

What do I need to do with the cat converters?
