I have a new-to-me e61 (08 535ix wagon). Has a few issues, and one mod. I have a half day tomorrow to knock one out. What should I do tomorrow?

1. Blower motor is dead. Its in the 40s currently so would be nice to have heat but not critical.

2. Valve cover gasket - tiny oil leak, slightly smokes after running for a while, only noticable when stopped at lights.

3. jb4+ chip. Extra ~70hp

I KNOW WHAT I WANT TO DO BUT WHAT SHOULD I DO
