White smoke

[rplant]

I have a 02 325i and today after filling up with gas, I started my car, and filled the gas station up with white smoke, started driving home and my car was running rough, ses light came on also, the dealer could not see me today and needed my car......so I took it to my local garage and found that a vacume hose had dry rotted that went from my dip stick to engine block, they replaced that and car runs fine, how ever it still smokes bad on start up. the shop told me ot should stop after a few days of driving, because my o2 sensors were still in "retard" mode.....has any one elese had this issue...

Please help, don't want to be ole smokey

Is there any sign of oil in the coolant or vice versa?

[rplant]

None that I can tell, the smoke does not smell like burning oil, more like fuel

[witeshark]

I was thinking of vapor from the coolant, like in the event of a head gasket leak. Unburnt gas should ignite instantly in the exhaust.

No oil leaks, just had the oil changed last week, no smell of burning oil at all....

you know. my 330 had white smoke occasionally also. Usually when I let it sit for a few days. Would idle rough for 2 min and then be fine.

Shortly after my oil backpressure valve...or ?cv went bad. It might be that? Can someone tell me the correct name for that part? Its under the intake manifold. its a bitch to replace.

possibly that?

Thanks for the heads up guys, I think I might be changing my M62TU OSV soon and was contemplating doing it myself. The mechanic wants $1000 to do that, and change the rocker cover gaskets, which he will do by removing the inlet manifold as part of the process, do I hand him the hard earned $$ or attempt the OSV without removing the inlet manifold myself?

You do not have to remove the inlet manifold to change the PCV, it just takes a bit more time, did mine in approx 1hr...

Marti you are a full on legend. I expect that I'll be leaning over my motor for several hours in excess of 1 hour, wishing that you lived on the other side street, rather than on the other side of the world.

It is a bit of a back breaker, but after youve done 3 you get use to it, also replace the Torx bolts/screws with normal bolts, it will make it a damn sight easier if you ever need to remove them again, if you get stuck removing any of the old ones I have a few tricks.....

I did pick up on using non torx bolts, but do you recommend using a standard hex head, or an allen key head?
Is changing the OSV on the 3.5l just as much a PITA as on the 4.4l ?
