The addition of a vacuum hose from the CCV to the back of the intake manifold to one of the capped off ports.

I read further into the thread and it seems that those who have done this have seen almost no oil consumption and have had no negative side-effects. I only read a few pages past that point though, so I was going to finish reading the whole thread before I did anything, just haven't had the time to do so...

yes, it seems like an easy thing to try. however, you need to verify that you have no other vacuum leaks - they specify replacing the dipstick tube o-ring, which is a good idea. i did that a while back.

also, installing a PCV valve in that line from the CCV to the IM would be a good idea.

this mod is likely good for warmer climate applications. personally, i don't want any condensate going back into my oil pan, and i don't want any possibility for the CCV freezing, or the drain line from the CCV to the oil pan freezing (or clogging) - that is a recipe for oil hydrolock. so my setup works for me. ;)

but you should do this - i'm curious to see your results! :)

Missed a perfect shot by .5!

Good lord what's wrong with it?

I'm not sure. It just eats it up. The problem seems to be pretty common. This seems to be on the more extreme side of the scale. Check the last page of this thread.

The weird thing to me is that some people don't seem to have this issue at all, which makes me wonder what's different.

My M54 consumed no oil for 7500 miles. There were some concerning things in the Blackstone report, so I'm bringing my next change down to 6000 miles. Hopefully it was just all the crud from the previous owners and the heavy maintenance from February washing away.

Anyway; everyone talking about oil consumption makes me nervous, but I check my level each time I fill up the fuel tank and I haven't seen the level getting lower.. fingers crossed.

I use the BMW Twinpower 5w30 oil.

Before I changed my ccv I got the yellow light at 3500 miles, after I swapped my ccv I get it now every 1500-2000 miles... I did a little reading and many people said swapping their ccv especially to a cold weather version one increased the oil consumption...

A few mechanics I talked to about this say that oil consumption is normal for the M54... the only thing I don't understand is why it's so extreme sometimes. Quite a few think it's just because the CCV system is a POS design and I'm inclined to agree with that, given the fixes for the problem are both CCV-related.

If you have no consumption now, just you wait. lol

all engines consume some oil, especially when driven aggressively. nothing to be done about that. but i can't agree that it's 'normal' for the M54 to consume this much oil - because, really, i was using more oil, and now after my CC/PCV setup, i'm not using much at all. my driving style has not changed. my oil choice has not changed.

Which is a nod to the fact that the CCV in the M54's system is a steaming pile of shit.

could not have said it more eloquently myself. :applause

:cheers

I would like to put my $.02 worth on this oil consumption issue.

I used to have to place a quart once every 900 - 1000 miles on a M1 5w-30.

Yes, I have just about replaced all the oil related parts like you all have.

Now, after 2,200+ I still have not put in any oil on M1 0w-40. Knock, knock!

I still do not know using a different grade have to do with oil consumption.......Maybe you guys might have the answer or at least a theory.

you've got knocking... that's bad. ;)

oil weight is an interesting variable here. i have always run 5w40 shell rotella T6 in the ZHP, and i definitely used oil with it before going with the CC/PCV setup. it's not really any thicker than a 5w30, but your 0w40 is thinner. in theory you'd actually use more oil (blowby) with that's obviously not the case with you.

maybe there's new-yet-defective CCVs out there. i dunno. i kinda have to go back to what BP said above. ;)

Yes that is true but I'm OCD. I have it synced perfectly to zero out every 1000 miles. Ya I know this sounds weird. [emoji849]

Tried to redeem myself, missed again.

I don't think you'll get it just right... I've been cheated out of major milestones as well despite absolute spot on reset points, only to have a .1 or .2 difference. I'm fairly certain that the mileage recorded by the odometer isn't 100% exact...

Ya that is a good point. I tried to take this in stop and go traffic which makes it kinda challenging.

It sounds like the parts helped?


I'm using Castrol Syntec 0W40 and will be doing an oil change soon. I've only had the car for a bit over a year, so it's only had 1 oil change so far. I'll see if it settles down a bit. Maybe I'll try Total 5w40 after. It seems decently priced. Most of the euro oil seems to be double the price once it's not 0w40.

holy crap wow

wow that is very interesting. Solving or reducing our oil consumption issue could be as simple as a new vacuum tube. Can whoever is going to do this do a write up (I know its simple but I like pictures) on the size and length that worked? We probably need a new thread just for this fix so we can start comparing results anyway.

I plan on doing the o2pilot mod but not sure when. Will write a diy when I do it if someone else doesn't before me...

I'm curious if the ZHP has that second vacuum nipple in use as the video mentioned since our cars don't have the muffler with the flap in it.

O2pilot is the username of the person who figured it out over at bimmerforums...

cool video, thanks san for finding it. it 'confirms' what i was thinking @ 9:00 in the video re: increasing vacuum.

my issue with the vacuum line addition to the CCV is that the vacuum level is unrestricted - also, what about the possibility of sucking oil up out of the pan if the bottom cyclone area of the CCV is clogged?

this is why i prefer my setup. i know where everything is going. ;)

Temporarily at least il try the o2pilot mod and see if it helps with oil consumption... if it does then I know the culprit and I will eventually get a catch can...

yep, that would help. however, without a PCV you might notice weird idle issues. i did before i installed one.

Guys, it is important to note that O2pilot specifically said that a new CCV system is required if you are going to implement his mod. I'm guessing that because of the mod, the new CCV system won't ever have the clogging problem again, which is probably why he says that you need a new system for everything to work as intended. If you use an old, clogged up system, you could have problems.


This is why I'm saving up for a whole new CCV system before I attempt this.

Did you ever do a full write up on your catch can setup? If so, can you provide a link. I'd like to save it for later.

why don't you wait for san to test? then you can decide if you want to do the whole new CCV, or a catch can setup. don't spend the money twice!

not a full one, but i do have the details from the CCAF setup here:

http://www.zhpmafia.com/forums/showt...211#post467211

since my entire setup is a prototype right now, i have been monitoring it, and i have decided to make some changes. i'm replacing my can with something with better baffling and inlet/outlet design (either the 42draftdesigns 'ultimate' can, or the mishimoto baffled can), and i am moving it to the drug bin - this is because it will be easier to service, and these two aforementioned cans are larger than the one i have now, and won't fit anywhere else!

once this is done i will document it a bit better. i have been thinking of making a kit, too (with CCAF option :)).

I had my hand back there awhile ago to check for a split cap on the bigger port (it was split), and I do not remember a vacuum line on the lower port. WE don't have the exhaust valve anyway so it would make sense if it was missing.

So I read about 10 pages of that thread. O2Pilot had the mod on for at least 2 years and he did not suffer from any negative issues that he could tell (and it seems a number of other people did as well and all of their oil consumption was reduced greatly). So I guess the car doesn't care about the extra vacuum?

My CCV is like a year old so I think I am good to go. I just wish I knew about this when I was changing it so I could have put a vacuum line on before installing it.

In for both, the latter if I end up in a colder climate at some point.

Perhaps you forgot the rate at which I consume oil - every second I wait is more money down the drain. lol

The CCV route is just easier. I don't have to do custom mounting and routing to get it to work... everything just fits into place nicely, OE style. This is how I prefer things. Plus, I don't have to worry about emptying a can, or worrying about the can freezing or having to hook up custom heating stuff for it to work. It's just easier this way, which is the method I prefer.

If there was no other solution, I'd do a catch can, but now thankfully I don't have to.

My ccv is 15 months/ 30k miles old and I made sure to avoid short trips especially in winter so I'm hoping it's still in good enough shape. Only one way to find out I guess...
