By the way, I scored a M56 valve cover for $175 shipped, from a auto recycler on car-part.com, woot! Its a website that searches junk yard inventories. You have to call around and verify that the valve cover they have for a 2003 325i has the oil cap in the corner (M56), or in the middle (M54).

Price of a new M56 valve cover is like $600 everywhere I looked.

Here she is, cleaner than I had expected, but I'll still give it a good solid cleaning





And someone asked about the oil cap. The m54 oil cap works, sortof. I know why its a different part number. The M56 oil cap rotates off and then is hinged, so it flips open. The M54 cap will fit but it doesnt close squarely. I was able to put the M54 oil cap on with the M56 cap still attached and flipped open, this is the M54 cap fully tightened:

Hey has anyone found the need to buy some of those "standoff" screws for the plastic cover to properly mount to the valve cover and on top of the fuel rail? its item #6 here:

Views:	861

ID:	625239

I assume they just screw into the two threaded holes on the M54's fuel rail that my stock M54 plastic cover uses? OP must have just let the right side of the plastic cover float without them...?



Updated parts list for 2003 and later M54 guys:

Metal M56 valve cover (11127521086) $300 if your lucky, $600 MSRP
Top valve plastic "BMW" cover (13537515326) $140
Standoff screws/mounts for the plastic cover x 4 (13537515327) $40
Rubber grommets for standoff screws/mounts for the plastic cover x 4 (11127501588) $10
VCG (11127521009) $60
Spark plug gasket (11127521010) $20
VCG o-rings x 11 (11121437395) $15
Oil cap (11127500568) $10
Plastic connector hose (11157513756) $53
Re-use existing coils and ground straps

You'll only be able to install the 2 standoff screws on the valve cover. (A new valve cover does not come with the standoff screws contrary to what's depicted in the ETK, so they must be ordered separately.) The other 2 are installed on the intake manifold. You can't install the M56 intake manifold because it uses special fuel injectors. A tuner might be able to program your DME to utilize the special injectors, but IMO not worth the effort.

Thanks Andy, that's interesting. The M54 covers screw into threaded holes on the fuel rail itself. Guess they changed their mind with the M56. Bummer.

In other news, I opened up the covers on the underside of the M56 valve cover, and given how clean it is on the post-CCV side of things I'd say the CCV must do a pretty good job:



Also, I used a small screwdriver and very carefully was able to remove the CCV cap. Here's what's inside:



Its such a very simple contraption. The only way I could see this failing is if you had some really nasty thick gunk in there, but then, you probably had other issues too

Hey thanks for posting those pictures of the inside of the CCV. That's pretty cool. It looks a lot like the N62 CCV. Have you tried to see if the cap from the N62 CCV repair kit (11127547058) will fit on there? It looks like the other pieces wouldn't work though. The spring looks shorter on the N62.

I don't think it will, based on careful examination of the photos. The N62 CCV cover's tabs are all equally spaced around the cap, but the M56 CCV has 3 "groups" of tabs that kind of form a left and right set of tabs. And the diaphram looks different, one has holes and a nipple, the other has no holes and a flat surface.

Darn, having to change coils on my 7/02 build e46 makes this fairly expensive looking...

Did you guys notice the different partnumber for the suction pump? Did anyone change that too?

It looks like the sucking jet pump itself is the same, but they integrated the fitting on the end that plugs into the intake manifold to probably help eliminate hydrocarbon escape via the intake system. You'd need that new sucking jet pump if you installed the M56 intake manifold along with the injectors & fuel rail, and also a 5 bar fuel pressure regulator. That quick connect fitting won't attach to the M54 intake manifold.

What sucking jet pump are you guys talking about? is that the secondary air pump (SAP)?

So consensus is to stay with the M54 part? Fine, saved another 50

The one that does vacuum for the brake booster

I attached the M56 hose from the valve cover to the M54 hose coming from the air distributor so that the hose that goes to the other side of the air distributor can stay intact, for equal pressures across the intake. I used a 3/4" 90 degree barbed brass elbow linked to the hoses with some 1" heavy wall 3:1 adhesive heat shrink tubing. I used super glue to temporarily hold the pieces together. I used new hoses and I installed a new air distributor as well because the air passages can get clogged with gunk.

But I don't have the stock intake manifold anymore because I have the ESS TS2 kit installed. It has its own hose that runs from the stock M54 valve cover to it's PCV. I'm wondering if that same hose will simply connect onto the M56 valve cover, which would mean the "nipple" would need to be the same.

Another question to ask to get the answer I need would be if anyone knows if the new shorter CCV hose has the same connector as our stock M54 CCV breather hose? It's simply a shorter breather hose?

No, the M54 hose will not fit the M56 valve cover. The M56 valve cover nipple is the same OD as the M54 hose.

Again, the M56 valve cover nipple is the same OD as the M54 HOSE, not valve cover nipple. The HOSE that fit INTO the M54 VC is the same size as the nipple on the M56 VC. So no, it doesn't fit.

Installed!



or



M56 valve cover gasket is so much easier to install than the M54.

Thanks xavierbk for clarifying the hose size, saved me from being stuck.

No problem, glad I saved someone from the headache I went through. Ended up buying some hose, clamps, and elbows to make a hose myself.

Never posted a pic of mine installed in this thread. This isn't completely back together and before I fixed the hose.

Dang I love that yours is black like that! Did you have it powder coated or did you spray paint it?
