If they are the original parts fom a 2000 model car, it is safe to say that if they have not leaked, they will soon. I would bet money that the connectors crumble to bits if you try to disconnect the hose.
Not to mention the yellow goo that is probably inside the dipstick tube, where the VCV line attaches.
If you want some peace of mind for the next 5 years or so, just replace it all now. Just try to find the lowest priced quality parts out there, and bite the bullet. Avoid the "Kits" for the most part, since buying the individual parts is usually cheaper. Especially avoid the ECS kit, since the price is not that great, and the shipping is ridiculous. For what they charge, it should be hand delivered by a bikini model with daddy issues.

You may need to remove the airfilter housing or go from underneath, however, I usually can do this from under the hood. Find the hose that connects to the dipstick near the base of it, and follow it with your fingers back toward the bottom of the CCV, feel for softness, tears and oil. If it is soft, it is likely collapsed and leaking vacuum and oil.

In a pinch, 3/8" fuel line will work as I recall, but the connector on the bottom of the CCV is tricky and it is much easier to figure out how it works when you have a new replacement hose, with CCV connector, in your hand.

Just want to say thanks. The butterfly fell out of its slot and won't let the DISA come out. I have to order it for now and drive it around like that 'till it ships. Gonna do that lower boot also, don't know if its bad or not but what the heck.

edit: It's a pricey part!

Hey jfoj,

Read your thread numerous times, and i am working on trying to improve a bouncing idle upon a rolling coast in neutral on a rebuilt engine I swapped in a couple months ago. I did a whole ccv replacement, new spark plugs, just recently in the last week replaced upper and lower intake boots and cleaned icv and tb. I pulled my disa, and it seems to be in good working order. My question pertains to the disa. Mine holds pressure when I cover the hole, but the flap isn't all the way closed. It looks like it is about 80% closed when covering the hole and when I release my thumb from the hole it springs open quickly like it should. Is that normal or is the disa supposed to be all the way closed when covering the hole? And I ordered a new o ring, do you think that will help my bouncing rpms when I take my car out of gear? I have a constant steady idle when sitting but the higher the rpm is when putting the car in neutral, the more "bounce" I get.

For example, if I am disengaging gear from around 3k the rpms dip to about 500 then up to 1k then evens out at 700. If I disengage gear around 5k it will dip below 500 and bounce past 1k and bounce back and forth about 3 or 4 times before leveling out at 700.

Acceleration seems a little sluggish too and I think it's my vanos but would like to hear your thoughts too.

Thanks for this awesome thread.

My Ride: 2002 BMW 318 M
jfoj, This is a great thread and I have learnt a lot. My 2002 318 M (4 cylinder) has rough idling and stalling only once the engine has warmed to operating temperature. I am in Auckland, New Zealand, and we don't have temperatures below about 5 or 6 Celsius (50 - 52 F I guess). No problem at cold startup in the morning although the mixture smells rich to me. No codes come up. Any advice before I start working through your troubleshooting list? It seems to me that the general principles of your advice are applicable also to the 318 (4 cylinder) motor.

Yep, your good. Sometimes these pins get loose and can be ingested by the engine.

it was really loose on the plastic piece, had I tipped it a bit it would've fell in the manifold probably had to fish it out or disassemble it. The pin is magnetic so you may get away with fishing it out.

Anyway, thanks jfoj and whomever else contributed to the topic. Also gotta thank internet part sales at Crevier BMW. The valve was actually cheaper with them than anything I could online. My car doesn't idle like Michael J. Fox anymore.

divad31,

I think you might need to start a new thread and list everything done to date.

I know you have been working on trying to resolve your problem for quite some time.

You need good compression, good valve lift and control, good fuel mixture and good ignition.

You could possibly have a problem with wiring connections or something stuck in your fuel rail if you know your compression and leak down on the cylinder is good.

What is the status of the crank sensor? Has the transmission ever been out of the car?

VANOS O-rings? Camshaft position sensor?

Start a new thread, explain the symptom and list everything that has been checked or replaced.

Also suggest you get INPA as well as this tool may be helpful. You can actually find the software for free online if you look around and you should be able to find a cable for around $15 USD.

It's the same as both of my E46's, so I'm assuming that's normal since they both run flawless.

Yo guys and gals.

Anybody got the part number of the DISA O-Ring? Doesn't show it on here for some reason http://realoem.com/bmw/showparts.do?...79&hg=11&fg=40

Thanks

Ray,

There is no BMW part number for your DISA O-ring.

You need to read the DISA section of the monster thread I put together at the beginning of this post or click on the first link below in my signature. It will tell you EVERYTHING you need to know about replacing the O-ring on your DISA and the O-ring sizes. Most of the sources I listed are in the US, however, you should be able to source an O-ring locally or via Amazon UK?

Good luck.

Just read it again. How the hell did I miss that? Sometimes I make Homer Simpson look smart. Cheers.

The thread is a monster, it started out as a few short paragraphs, you can see what happened to it.

It is A LOT of info do digest in a single pass.

If I had time, I should really re-write it, but you will just have to deal with the sausage for now!
