Why keep any of that? If you are going to get another new/used motor it will have all that stuff on it. If you are going to get new/new parts to replace the ones that failed you are into big $, so do all of it or none of it. I can see keeping the oil pan just incase you damage another one.

This summer we have had to move everything, and we are saying over and over, why did we save that? If you need those parts, then you again have bigger problems and will be starting from scratch anyhow...
