The rectangular thing that the waste way oil comes out of is supposed to be a separator that sends coolant down a pipe to the tank and just puts way oil in the waste oil bottle. It gets gummed up with sludge and doesn't work so you finish up with coolant coming out of the oil pipe. Take it off, it is fastened on with a connector something like a hose fitting at the back, take it apart and clean it.

An open mind is a virtue...so long as all the common sense has not leaked out.
