Maybe replace the ignition coils and spark plugs if they haven't been already since you're there

I had considered that. Spark plug replacement is reasonably easy, I've never done ignition coils. Easy too?

Make sure you don't just get the valve cover gasket; get all 15 grommets too. You need some RTV for the half-moon cutout corners too.

If you're replacing the spark plugs, you've already removed the coils. Simply install new ones instead of replacing the old ones. Might not be necessary though. I'm on my original ones at 234,000 miles. As for the spark plugs themselves, if you're close to or over the 100,000 mile interval do them, otherwise don't bother. If you do, use NGK BRK6EQUP

You don't need to replace the ignition coils unless there's an issue with them. You already have suggestions on sparks, grommets, and RTV.

And for clarity, this is where the RTV goes, front and back:

Thanks for all the info. I appreciate it all. How should I know if the ignition coils, need attention? Currently, I am at 104,857 miles.

I strongly recommend getting an upgraded OEM VCG as opposed to the aftermarket one, or you might be finding yourself re-doing this job again soon. The price difference is not very significant. As Tangent said, it's very important to get new grommets. For the sealant, Permatex Ultra Black is favored here (apply to the half-moons both front and *BACK*, and the vanos joint lines on the front). Clean the old valve cover really well from the remaining oil on the gasket mating surfaces.

Have the ECM codes read to see if there are any errors that would point to a coil issue. AutoZone can read them for you or if you have a Peake, or similar, reader you can do it yourself.

Also, at 104K miles, if you have an automatic, change the transmission fluid and filter. There are many posts here on how to identify which auto transmission you have and how to do this.

Might as well do your Vanos seals if you haven't done them yet.

As long as you are going to be in there...might as well update the cooling system, belts, pulleys as well, if they haven't been done already.

One thing to note, is if you don't know how old or when the ccv system was last replaced, the vent hose that connects to the front of the valve cover may snap in two when you pull it off due to it being old and brittle, leaving you with a big vacuum leak..

Hi all. Just did the "work" on my car. Was VERY easy! It took my son & me a little over an hour to replace & check other parts.
I wanted to say thanks to everyone that gave me EXTREMELY helpful suggestions and help.

sansho - error codes - had checked @ BMW recently. No codes.
transmission fluid & filter - checked. all good.
mystic blue - cooling system - TO BE DONE soon. got too cold out. couldn't feel my hands. That's fall in New England. :-(
miko_10 - vanos seals - To Be Done soon.
ghmelb - ignition coils & spark plugs - checked, still in good cond.

THANK YOU to all!!!

My mechanic buddy suggests I do the whole cover instead of just the gaskets to really prevent any future leaks. I have 117k. Thoughts on that?

Waste of money unless you have cracks starting in it already... I have 234,000 on mine and the valve cover is fine.

+1 on the gasket.

I went through like this procedure three times until I figured this out. I had no luck with VR gaskets.

I've had good luck with VR. When my original VCG started leaking at around 100k miles I replaced it with a VR. The original was super hard and brittle at that point. At about 200k miles I replaced the VANOS seals and when I pulled the valve cover the gasket was still pliable and sealed perfectly. The new VR gasket I put in then has also been fine for the last 25k miles...
