Smoke from engine no matter it is hot/cold engine

[mat6689]

All, I have a problem after changing engine oil. The engine is vibrating like an old engine. Worst still, if taken out the engine oils measurement dipstick, you can see white smoke coming out.Checked with mechanic, he said this could be piston ring is "burning". Checked with AB, they said this is normal for Diesel engine (320D). Can anyone of you help me to check if your engine is "smoking" ? Or, any advise will be very much appreciated. Thanks.http://www.bmwclubmalaysia.com/forums/attachment.php?attachmentid=17788&thumb=1&d=1291984905

Good to know that 320D got a dipstick! Don't think the piston ring has worn out since 320d is still consider new.
