And what is the temporary fix? Here, when doing an oil change:
1) Start with 2 quarts lucas engine oil stop leak
2) Fill the remaining of the engine oil capacity with shell rotella t6. It's 5w40 synthetic diesel engine oil. Yes diesel. It's a popular oil in the BMW 335i N54 world. Has great cleaning properties and is safe for our engines.

Since doing the above I've been trying to get my car to smoke without success- it's completely gone. Been to the Canadian border with long traffic jams; been to Whidbey island multiple times with the long ferry queues. No more smoke, not even a whiff. And she used to smoke like crazy before the temporary fix.

Ill send you a PM with his contact. Yeah I hear ya with the suspension refresh, I'm in the same boat right now and I'd like to put a band aid on the seals until I figure out the suspension. I'll try the Liqui Moly treatment first cuz it's advertised for stopping blue smoke caused by leaky seals and lots of people have had great success with it.
If it fails, maybe I'll move to the Lucas oil for a couple months or so although I doubt it'll let me down.
I've heard mixed reviews on Lucas oil stripping out the additives in the oil, requiring much shorter oil change intervals. Not sure if that's true though, maybe Liqui Moly does the same. I remember reading it in one of the threads on bobistheoilguy.com

Thanks! I agree, with these band aids, better to reduce oil change intervals. I change every 5k miles which turns out to be twice a year for me.

Any thoughts on a mechanic who could do this for my 07 e70 4.8i, I live in Virginia? Texas is a long ways away. thanks

Few years back I did a voodoo dance - used some specialized engine cleaner (forgot the name, but it was mentioned in one of the forums), replaced the membranes (they were torn), used LM engine cleaner, and used LM 5-40 oil. At the time of treatment, it significantly reduced the smoking, but with DC traffic, it still smoked on longer delays.
As time passed, the smoking reappeared on shorter idles. I checked the membranes, they both were still intact, and I have used nothing but the LM5-40 oil. so, I think it is time to try a more permanent solution...

For 2K, that's a ahmazing price given the work/results. I would jump on it if I had that issue.

Back in early fall, I was at my Indys. Dunno the rhyme or reason, but he just dropped the entire block down with the subframe and goes to town on it.

No doubt the seals are sick like an old smoker's lungs.
I was just trying to eliminate the smoke until I do the front and rear suspension refresh and other miscellaneous. In no way I'm substituting this for a seal replacement.
I was just gonna try it for a few months see how it goes until I'm comfortable dropping more money on it.
Cuz if I'm doing everything at once, it seems like I spend way more than reasonable in a short amount of time.
