CCV Valve - Oil Separation Failure due to cold weather...anyone else?

You taking it to another dealer means you think there is something wrong with your car, the new dealer wants your business and says the valve is failing again. So they replace the valve and hoses under a parts warranty. Just because they replace it again doesn't mean the original dealer did so incorrectly. BMW parts carry a 2 year warranty that is why they did not charge you the copayment. So in a few weeks or so, when your oil level light comes on, you'll go back to the dealer and when you check your oil cap it will have some mustard on it, then you'll start this all over again.

well for one, this engine has never needed 3-4 qts/15k miles or 10k miles for that matter. i'm not a bmw novice, i own about 6 of them and am particular about checking the oil level and keeping up with maintenance. secondly, the hoses were not replaced the first time around, so yeah, they did do it incorrectly. that's not to rule out this won't fail again but i'd much rather a dealer that actually looks into the issue and attempts to rectify than blowing customers off and also botching up by overfilling oil. i won't be going back to bmw of morristown.

no one is saying your a novice, but have you considered just because you own "about?" 6 of them doesnt mean your by any means an expert. imagine, a man who owns 6 books, and, and another who owns 1 book, does this mean the one with more books is an expert? or that this man can compare his 6 books to the other mans? or that all books are made the same?

you can keep saying they did it incorrectly, that doesnt make it the truth. i dont have your invoices, or reciepts. i cant tell if they did or not replace the hoses. Just because they did not replace the hoses, does not mean they didnt do it correctly. if the part they replaced the first time was the Cold Weather version, then it is a parts kit(includes both hoses and crankcase vent valve), it is almost impossible to re-use some of the hoses when replacing the vent valve because you must destroy it when removing the original one. and the hoses that arent damaged when removing them can be re-installed. there is no law that requires you to replace the hoses, especially if there is nothing wrong with them. you are just not familar with the BMW repair process.

of course there's no law.. there's no law for many things, doesn't make it correct. of course i have receipts/invoices. your books analogy makes about as much sense as that dealer's convoluted reasons for why everything is "normal". You don't happen to work there do you?

If you are having problems with ccv valve why not do away with it. Blank off on the intake and simply run the breather pipes over board and beneath the car. This will take away all the fumes and you will have no valve to freeze up and cause the pressure problems. Having worked with Rover v8`s for many years this is exactly what happens and never any problems.

Because you are then likely to fail any annual inspection that covers emissions systems, requiring an expensive replacement of all the components that were removed.

I know its not correct procedure but I think you will be unfortunate to be pulled up on something like that, most garages wont even spot it. I know i`ve never been pulled up for it over her in England but maybe its stricter where you are. Anyway its just a cheap solution and food for thought.

The thing that I don't get is that this seems to starts to be an issue when the engine approach or pass the end of warranty period. Could it be that and older engine let more humidity/moisture to enter the crankcase than a brand new one (remember that the oil/water mix that is the cause of the freezing valve)?

It isn't any more likely on an older engine. If you have lots of short trips it can happen on a new engine or an old engine. If you clean out the hoses and valve periodically, it will never likely be a problem.

So for preventative maintenance do you suggest replacing the valve and hoses? And what do you mean by cleaning out?
Don't want this nightmare.
Thanks.

Do a quick thread search. TONS on this topic.
