It's pretty straightforward, you'll just maybe want to move a few things out of the way.

Here's a DIY on Vanos seal replacement that covers valve cover gasket replacement along the way.

I recently did the Vanos procedure and the only thing that held me up half a day was that the valve cover gasket had plasticized and practically welded itself to the cylinder head. Assorted putty knives and similar bladed objects in various places later, I got fed up and yanked in a couple locations I felt certain wouldn't crack the cover. It popped right off at that point, though I'll underline here, you may not face the same problem.

I used that same guide, and also had a plasticized VCG when I replaced it this past weekend. I used a hair dryer on high heat aimed at one spot for about 90 seconds. This softened it up just enough to allow me to separate the brittle gasket from the valve cover, and I was able to work my way around that way. This method worked especially well on the hardened spark plug seals that were stuck to both the car and the valve cover.

You may want to clean your injectors and replace your plugs (real easy) while in there. otherwise you'll do it twice. If you are really looking for a winning day, do the vanos seals too.

At your mileage, that is a good recommendation. Cooling system should be next on your list.

Does the valve cover require RTV sealant other than in the corners by the vanos? Looks like it could go on without sealant.

The hair dryer is a great idea.

On the recommendation of a local BMW Master Tech I met recently, I used Hylomar, and that's the only place I used it.

Replace the VANOS seals and the VCG while you're at it

Where is the leak? What leads you to believe it's a CCV problem?

On my car, the seeping VCG was exacerbated by inclines. If it sat for a while facing uphill, apparently the seeping oil would form drops which then fell onto the exhaust manifold. So if it's indeed a VCG, you will probably be able to smell and/or see burning oil under that scenario. You might also be able to see wet oil which has collected on the top of the rear O2 sensor.

Actually he let me use his. Google shows a number of products with that name, but this one is called Hylomar Universal Blue. Holy crap it's expensive!

Run your finger along the line of the gasket and underneath it. There is a ridge-like about 1/4" below the gasket. Run your fingers there. If it's wet, you got a leak.

If you're not sure, clean it dry with paper towel or a rug. And then check again after a drive. Don't forget to check on the rear of the engine. And don't forget to let the engine cool down...

Replaced with Victor Reinz VCG and 15 washers, I changed the oil cap gasket as well, the old one was ok. Wouldn't bother next time.- overall no gasket fusing, center spark plug wells brittle as glass basically fell apart on removal. The perimeter dry, still some elastic there, and wasn't falling apart. Checked the spark-plug well, and there was a a drop, so the seeping I had would be landing in there over a period of time. Anyways all needed to be replaced.

Another item checked off the list. Thanks!

There is a beautiful online TIS listed in QSilver7's thread today (1).

For example, for my vehicle, here are the TIS' for replacing the cylinder head and cylinder head cover.
