I'm sticking with another m54b30.. I suffered the dreaded oil pump failure.
On paper it sounds fairly simple. the Bentley book will be your best friend, but even at that it's no simple job. I expected things would not work 100% according to plan, as they always do with cars (more so BMW). But really it's a pain. you sound like me, no expert, but still knowledgeable and somewhat mechanically inclined, it's still going to turn out to be much more work than you expect.
If you do it, my advice is a).get a bently book and b)only do so with someone who is experienced with BMW's and engine swaps. I can't explain what you'll be getting yourself into, but like me, you will learn when you get into the serious stuff. Live and learn.
Good luck friend.
