Just be careful because every time you jump a battery you are shortening it's life and straining your alternator. You could be setting yourself up for a costly repair by constantly having a battery with a low state of charge.

Yeah I'm gonna try to run it every day until we move. Then I can just disconnect the battery and maybe charge it when I need to run the car.

Maybe use a slow/trickle charger or something?

You can try that, at 9.99 you don't really have anything to lose. I have never used that type. This is what I use:

That's a hell of a charger. I'll maybe try the cheap one and see how it works.

Something is up...

I ran/drove the car on Tuesday for a while after jumping it. It should have started up just fine yesterday but it was even more dead than the day before. Alternator? Hmmm well maybe not since all electronics work fine when the car is running. If the alt was bad then there would be nothing. The battery is brand new. Unless there's an open circuit or some shit draining the battery.

Fuuuuck this car.

If you car stays running after it is started then your alternator is doing its job and keeping your electrical system up and running. Is your alternator strong enough to actually recharge a dead battery in a reasonable amount of time? - that I cant answer.

Invest in a trickle charger, disconnect your battery (or even bring it in to your house) and charge it for like two days, or follow the instructions that come with the charger. Disconnecting is critical because if you car is drawing your battery down, charging it will be useless. Once the battery is known to be recharged, you can better gauge if you have something draining the battery down. Keep in mind that a battery that is being charged releases hydrogen gas, which is flammable.... so dont be a dummy where you recharge it.

There is a test that I run to determine if a car is draining a battery down. It's called a parasitic draw test and it can be very tedious and difficult to run and if you determine that a draw is present, it's even harder to diagnosis where it is coming from. That would be a job for an electrical specialist or possibly a BMW specialist.

Aight. Yeah the alternator is doing it's job. I'll get the charger soon and try to charge the bitch to full.

I was reading online that it's possible to see if there is a draw by disconnecting the negative wire from the terminal and then putting a test light in between the negative post and the wire. Positive of the light to be connected at the cable end and the negative of the light to be connected at the battery negative terminal. If it lights then there is something on. Start pulling fuses to see what's causing it. No idea if that is right or not...

This test in inaccurate. Your radio and various other modules have a keep alive memory that will, by design, create a draw. The draw is very small, usually around .025amps or 25 milliamps, but that is more then enough to light up a test light. You need to disconnect the negative cable and put an ampmeter, not a test light, in series with the battery. After that, you wait until all of the modules go into "sleep mode" and take your draw reading. If it is greater then 50ma then you have an excessive draw. Start pulling fuses after you get your reading and see which circuit is causing the draw. It's so easy that I only charge 189.99 TO START!!!! and in all honesty, I wouldn't even touch your car.

Went ahead and got me a float charger. I'll let you know how it works out.

Revisiting the leaking oil thing...

Since I finally have a driveway, I plan to work on this soon. Reading online, they say to replace the valve cover gasket and rubber grommets.

Valve cover gasket set: http://www.fcpeuro.com/products/bmw-val ... 1120030496
They say you need 15x of these too: http://www.fcpeuro.com/products/bmw-val ... 1121437395

RTV sealant is used?

People talk about it here: http://forums.bimmerforums.com/forum/sh ... ver-gasket

A similar DIY (not my engine): http://www.dvatp.com/bmw/valve_cover_gasket/
M54 DIY video: http://www.youtube.com/watch?v=B-TLgNCmTlY

Shall I replace the spark plugs while I'm at it? As far as I know they've never been replaced. I've got the M54 engine.

Thanks dawg!

This video is a good one. All good stuff. If you can follow it you should do fine. I only made it as far as "BMW's are not known for oil leaks" in the other link you posted, laughed until I pissed myself then left the page.

Use this silicone sealer:
http://www.permatex.com/products-2/product-categories/adhesives-sealants/sealants/permatex--black-silicone-adhesive-sealant-detail
Use any "Brake Clean" you find. These two things are available anywhere you buy parts.

A clean and dry surface is the most important part of the job. Anything the gasket touches needs to be thoroughly cleaned. You can see how to properly use the RTV about 5:00 in part 2 of the video.

When it comes to the spark plugs, just follow your maintenance guide on when to replace them. When the valve cover is off they will be easier to replace.

Aight, thanks man. I'll try my best on this and see what happens. Hopefully this stops the leak. I need a deep socket for the spark plugs right? They're Bosch 4417's. 3/8s or 5/8s"? They say to replace at 50-60k miles.

Any parts house will have the spark plug socket you need, likely 5/8 in size. If not, hit up Sears. http://www.craftsman.com/search=spark+plug+socket?storeId=10155
