Even the walnut blasting is used sparingly in extreme cases because the noticeable effects are minimal (that statement comes from BMW engineers/PUMA). The only before and after improvement I have seen is a smoother idle.

But I don't know if I'd want nut shells floating around my rings.

2006 BMW 750LI is smoking

Hello everyone, can you recommend someone who could fix my car for much less than the dealership? I'm in Buffalo NY. I just joined this website. My 06 750 just started having that smoke problem that you all have been talking about here. The dealership says it's most likely the valve issue discussed here, so for them to fix, it would cost a fortune. If I let it idle for a while, then punch the gas pedal, smoke comes out of the tail pipe. Thanks!

First - welcome my fellow Buffalonian (my birthplace) - can't say I miss it but it was fun growing up there. From my previous post my car is still running strong with no smoke. Fiirst try the inexpensive recommendations before handing over your hard earned money.

Wooooooow

In our country they replace the valve steam with the parts for 1500$ including the parts.

The whole engine will cost 4000$ low mileage imported from Japan.

Most of the valve steam issue is from not replac the oil for long period. And this common issue in all Germany cars such as Mercedes , Audi as they use the the same brand

I think the prices is over. If its like that I wish that I own garage in US.

I highly recommend BMWOEM1 for valve seal repair

I made the 6 hour drive to have BMWOEM1 fix my valve seal issue. I have a 750LI with almost 150k miles. He did a great job, I'm so glad I went to him instead of the BMW Dealership. Saved a fortune and I think he did a better job and in less time than my dealership would have. It was an easy trip to his house in Long Island NY, all highway driving, his place was just off the highway. This guy really knows BMW's inside and out. He made the job look easy. My car used to go through oil like crazy, there were so many leaks. Since he fixed everything a few weeks ago I haven't lost a drop of oil, engine is sealed tight with all new gaskets and the new valve seals eliminated all the smoke from the exhaust. It feels weird now, not having to add oil all the time . Very happy. Anyone considering seeing this guy for any major BMW repair should not hesitate. He really really knows his stuff and is very fair with his prices.

Mein Auto: 04 BMW745li
I am new to Bimmerfeast and I am having the same issues with my 745. I just purchase a 2004 BMW 745li and at the time of purchase it was not smoking till two days after. First my logic7 amp went out then it started smoking white smoke from the tail pipe on takeoff. I am debating on keep it or selling it. I pretty sure it’s the valve seals from what I have read on the forums. Is there anyone in the bay area (San Francisco) that is dependable that would be able to replace valve seals for a good price? BMWOEM1 be nice if you lived out in the bay area…………Is it common for exhaust to only come out of one tail pipe? Thanks

Only one pipe is open during idle, the other closed by the exhaust flap. If I had the time, I would make a cross country trip and do a bunch of stem seal jobs.... But for now, I guess only northeast BMW owners can take advantage of my services

I've been trying many of the suggestions in this forum and it appears that I may have fixed the problem. My car is not smoking at all anymore.
I went and took off the vacuum tubes and dumped out any oil in them, there wasn't much. I changed the oil and placed a heavier oil, 10-40 synthetic mobile one, with some stop leak along with it. I also looked at my K&N air filter and it was plugged tighter than a tick, so I figured I better clean that. I also filled it up with oil just a little over max. That was accidental, but I don't know, if there is a vacuum issue, maybe that could make a difference as well. I did so many things, I do not know which things may have helped, but I've been driving it for several days without seeing any smoking, even in stop and go traffic where I used to see it bad. So if I see any more smoke I'll try to let you all know.

You need to double check the install of the CCV's first. The easiest way to check for valve stem seals is to drive the car until fully hot and let it idle for about 10 minutes. Next, rev the engine (while in park) to about 5k rpm quickly and release the throttle. If you see a cloud of smoke from the tail pipe, it's most likely leaking valve stem seals.

Double check your CCV install and while you're at it pull your CCV hose(s) and check for oil.

Valve Stem Seal, SUGGESTIONS?

I think I'm starting to develop this issue now. Idling like in driveway then rev it has a little bluish colored smoke... Ugh. It doesn't really do it unless it sits n I rev it. Letting it sit n then driving seems fine from what I can tell

But I am loosing about 1 qt of oil every 2k miles I'm noticing last couple months... 110k on it.
