My Ride: 2004 545i
I noticed a puff of smoke after long idles durring traffic hours and during hot temperatures around the 175k and especially after oil change maybe the viscosity. I have not notice any noticeable smoke in months at 189k
Keep a few quarts of oil in your trunk and check the oil level weekly at cold start up i regularly add oil and coolant once a week.
Either way im looking at a $5k job for the secondary air injection, engine needs to be dropped and my mechanic will replace valve seals, coolant transfer feed and gaskets.

Back right of engine if you are standing in front with the hood up.
Owner's manual is here: https://5series.net/info/2004_5_Series_Manual_US.pdf

If it only smokes after long idle its not going to be the valve guides. The valve guides will give lots of smoke on start up after sitting over night. The idle smoke is cause by a vacuum leak somewhere which prevents the internal pressure (negative pressure for bmw and vw but most cars have positive pressure) from staying negative. The normally negative pressure keeps those stupid little flaps closed preventing oil from splashing in them. The reason why its so random is sometimes they just stay closed anyways and other times they will open allowing oil in which is why it only does it at idle. When at driving speeds your creating enough negative pressure to overpower your vacuum leak. I found my leak in my oil pan. Tiny little pin hole from a rock hitting the drain plug and cracking the weld ever so slightly and since I replace that no more idle smoke. YMMV but I wouldn't go to full freak out mode and rebuild the engine. Just find your vacuum leak and fix.

I have owned a 2004 745i and now i own a 2005 545i. The 745i had 107,000 mile when i purchased it . The 545 had 99K.....
I found a semi fix for this engine. I tried this on my 545i with my last oil change by using 10-60
(heavy i know but the valve stem seals are having that problem) right now because it is spring, i will decrease the weight in winter. I used what is call ATP AT-205 RE-Seal Stop Leak. It worked !!!!! i have had it in my 05 545 for 1000 mile and the smoke it literally none existent.. ...
Well i will keep you updated on any changes. so far so good .. FYI they use 10-60 in M3 and M5 .. can also be used in naturally aspirated BMW.

they say it should make a sound because PCVs have a bead in them that function as valves. my gf's 05' F150 PCV was a rubber check valves and you could barely hear it. i blew air into it by mouth and i think it loosened it up and we never noticed a sound after that. I'm still learning BMW, ive only had one since Thursday this week

this video eventually goes in depth to explain why high viscosity oils shouldn't be used
