530 freeze oil dip stick oil separator
My 530 i stalled out today, started missing and then smoking like it was burning oil. I thought maybe a momentary ovre rich condition, but oil smoke smog began to billow out the back, looked for a pull over spot and then lost power. Engine would not turn over, like suddenly lack of battery power? Busy street, so called quick for tow. Oil drops out of exhaust pipe, very very scarey.
Local mechamic that towed it indicated it was a common problem to this model, which is a 2004 530i 4 dr sedan auto 6 spd. Mech just called back indicating this s a common BMW 530i issue, called it first frozen dipstick (is that me?) phenomena, where moisture freezes in dipsrick, apparently no other vents work right, oil filles cylinder through ? not sure, maybe head gasket?
He said it is about 14 parts, initially $1100 for parts and about same for labor, 10 hours at $110/hr.
I searched for something like this on this e60 site, found nothing. Any ideas?
One more thing: Re: 530 freeze oil dip stick oi
Local mech. from Tow shop (it is Sunday and about 30 degrees in Minnesota) noted that the tech bulletin he was reading indicated that it is usually dip stick tube that freezes and cylinder filled with oil. This was first indication of this on my car. It is a 2004 530i with about 60K miles, this is my second year of ownership on it. No smoke ever before. H eindicated that new parts would include a dipstick heater, intake manifold heater, plugs,etc. I have not checked if it was driveable, but when this happened, car stalled, and would not turn over again.
Any ideas? I have the service manual and do much of my own work, but also have towing insurance just for this type incident.
Thanks for any suggestions.
2004 530i auto,

the moisture in the oil that freezes. The moisture gets in the oil due to short, low-speed trips.
There is a funnel-shaped device in the front of the engine which separates the liquid oil from the fumes, and sends it down the dipstick tube to the oil pan.
I've not heard of heated components; only a setup that is insulated. The problem with the six is that, apparently, the components are in a place that doesn't get a lot of engine heat. On the V8, the separator is actually inside the engine.
If you are a DIYer, the job can be done, but it is not a simple one.

Re: Not uncommon in northern climes. It's actually >>
Thanks for the input. I wonder if BMW has a list or bulletin to identify the usual suspects that should be changed? Plugs,do O2 sensors get hot enough to burn off any film that may have worked through?
Thanks for any other inputs.
These are the parts you want to replace (m)
Get the insulated hoses.
All of these parts are under the intake manifold. Some have replaced them without removing the manifold.

Thanks much for the help: I do much of my own work, the BMWCCA card helps w/ discounts.
