OE M56 valve cover breather hose on (Part # 11157513756)

To top it all off, here is everything with the pretty engine cover. All done with OE parts.

 

OE M56 valve cover breather hose on (Part # 11157513756)

Hey did you happen to notice of the connector is different on this new breather hose, or did you only have to get a new one because of the length (and routing of the hose)?

I'm wondering if my M54 breather hose will connect right onto the M56 cover's "nipple" just the same or not...

 

Subscribed!

 

Any update?

 

What? M56 valve cover fits onto M54? This is the first time I am reading this :wow:
In for final result

 

^^^^ Thats why i'm in here - this works will be getting done by me with a damn quickness!

 

Updated the post. Waiting on one more part until it's complete.

 

Good thing you got the black plastic cover with the valve cover, as it doesn't show up in the BMW parts catalogue anymore, must be NLA.

 

It seems to readily available brand-new. Part # 13537515326.

ECS Tuning sells it:

There's also a used one on eBay right now:

Interesting. I still prefer my catch can. Adds extra vacuum to the crankcase.

 

That's seriously fvcking brilliant. I wish this worked on the M52.

 

oh man I just did my gasket 2 weeks ago, If I saw this mod before it would defenitly go to my engine! Btw , does it fit M52TU?

It would work on the M52TU, since the M52TU is essentially an M54. However, I don't think the M52TU coils would fit, so it would probably require you to upgrade the harness for the coils. The M52 is a completely different animal.

Also, I updated the original post.

That's interesting, thanks for posting. RealOEM doesn't show that part, although it does show the M54 version.

 

Nicely done .... when the weather warms up a bit, let us know if there are any driveability issues that surface. Wouldn't expect any, but let us know.

 

I'm curious how this has never come up before... Seems like an oddly good idea.

 

How does the black plastic "BMW" top cover attach to the valve cover?

 

You must be one lucky sumbit¢h cause there's nothing for M56 valve covers on ebay.

The valve covers themselves run just under $300 new, which I believe also includes the VCG and spark plug seals. Yesterday, there was one used black plastic cover for around $75 on ebay (search on the part number 13537515326).

 

Plastic? Pfft. Gonna polish the aluminum one til I can see god.

 

All you need the is M56 SULEV valve cover + gaskets and the SULEV dipstick?

 

I've been looking at this too ... here's what I see (appreciate any corrections):

I don't think you need the SULEV dipstick, just put a rubber cap and hose clamp on the connector that will no longer be used.

Don't know if you need a new oil filler cap or whether the existing one can be reused .... they are different part numbers.

Parts list shows a grounding strap (pn 12421437633) from the valve cover to someplace. You could probably jury rig this yourself versus $23 for the strap.

You'll need a hose (pn 11157513756) to connect from the valve cover to the air distributor on top of the intake manifold. There's a picture of it above.

You'd want 11 new rubber grommets (pn 11127838077) for the valve cover.

Great time to replace your spark plugs, if that's about due.

 

This would allow me to remove my whole CCV system for the M54b30? I will need to do some more research to see if this is a viable option. It looks to be. I actually just recently did VCG and spark plugs, however my valve cover was slightly damaged removing the original ROCK gasket. It is fixed "for now" but I will need a new valve cover and I am seeing this as a great option. I am wondering how OP found the valve cover so cheap lol.

 

There may be a caution here ... looking at realoem, in 09/2002, BMW changed the coil type, which looks to have a different connecter than prior to 09/2002. So for those of us who like this CCV delete idea, it "may" require new coils and a new coil wiring harness. I need to look at this further, however, wanted to mention it as a potential goink for those of us with pre-09/2002 builds. It's possible that our pre-09/2002 coils may fit the M56 head, but don't know that yet ... anyone shed any light on that?

 

Yes. This will require new, plug-in, type of coils rather than the ones you have to secure with screws, and also new wiring for the updated coils.

 

So, if one were to buy all the parts new (with discounted BMW dealer prices and Pelican Parts on coils), required for a pre-09/2002 e46, this would be an $875 project:

Coils ( 6 @ $38) = $228
Spark plug wiring harness $112
Metal valve cover $297
Top valve plastic "BMW" cover $140
VCG o-rings (11 @ $1.36) $15
Oil cap $10
Plastic connector hose $53
Ground strap $20
-----------------------------------
Total $875

Those with 09/2002 and later could get away with $535 for the new parts.

 

Just so that no one misunderstands what you're saying, I want to point out that you're only talking about pre-09/2002 M54 cars, not 323i/Ci or 328i/Ci cars.

Thanks, good point to clarify, and, yes, you're correct

 

so, does this actually work? Is there really no more mayo in the ccv? From an engineering standpoint, does this mod affect anything negatively? Will the computer be reading different crank case pressures that what it is expecting?

2004 M54b30 right here. Highly interested in this mod. I hate the mayo every winter.
