[E92TiAg335i]

Hey guys. I'm at 57k miles on a fbo e92 335i 6mt. I just took my car to the dealer to get a new battery a little while ago.

While there, the tech wrote "note: valve cover gasket starting to leak."

I looked and I didn't see anything.

Today, I think I started smelling the valve cover gasket ever so slightly.

How imperative is it for me to fix it immediately?

I drive a lot, but i'm also moving into a new place soon, so a lot of money will be spent on that.

Is the valve cover gasket super serious? How much should i pay for this job?
