I saw the answers to a question I posted recently highlighting the disadvantages of having too little oil in an engine, but that got me wondering what if the complete opposite were to occur!
I know that having an excess amount of oil in the engine is a terrible idea, but I don't actually know why. It seems to me like the excess oil would eliminate at least some of the disadvantages to not having enough oil (like for example the parts would not rub and create friction because there would be plenty of lubrication). Due to this, I am guessing that having too much oil would have very different disadvantages to not having enough oil.
If we imagine that for whatever reason, the engine was full of oil (and I mean literally full to the brim, you can't fit any more in it unless you pour it all over the engine bay):
- What are the disadvantages to having way too much oil in the engine?
- How do the disadvantages differ from those that occur from not having enough oil?
- Would the engine last longer than the same engine would with way too little oil?

The linked post does not answer my questions fully, here is why:
- The accepted answer only says to take out the oil but doesn't really explain the damage that can be caused
- Paulster2 said "you can cause damage to the crank and rods themselves" but I don't necessarily understand why so I thought I'd ask a question rather than just adding a comment
- He also said that some of the moving parts hit the oil 20 times a second, but I thought they did that anyway!
- Second answer down, which starts to make some good points, could do with some clearer explanation as I'm not sure that I understand it fully
- The rest of the answers do not provide as much explicit detail as I am looking for in the answer to this question (they are quite short for the most part)
- This question also has a framework of what happens internally to an engine and what the side effects are as well as component of what the fundamental differences are regarding effects when compared to lack of oil
- Also, I asked this question in order to build a theoretical understanding of the problem. The other page suggests how to fix an overfilled engine (practical application)
