Fan shot off into radiator and there is a lot of oil in my air filter.

It's oil not radiant fluid and radiator is fine

Usually the fan will destroy the radiator, so when both of those are listed together, what should we think. Sounds like you have a bad blow-by problem, but I'm not looking at it either. I have no clue if your engine is blown, if it's running, it's running, how well, you know better then we can guess. It should be check out with someone hands on.
