This was almost exactly the story at the end of my 2008 451. Valve cover leaks, spark plug tube leaks, oil everywhere. I had 189,000 miles on mine at the end, it served me well.
The only difference is I simply sold mine as is, with full disclosure to the new buyer, and moved on to a 2016 453 and never looked back, it's twice the car.
