Unhappy Engine smoking pretty bad now

I have a 04 545i and have had it for the past 100,000 miles. I bought it with 48,000 on it. I have had it serviced at the bmw dealership for the entire time I had have had it. At about a 100k it started using a quart of oil every 15,000 and from there on it just used a quart more and more. It started out about a year ago just smoking at idle speeds (133k miles) and I asked the dealership what is going on with it. They told me these cars just seem to do this and its a very expensive repair and the best bet is to just keep putting oil in it.
I had a side mechanic tell me it just needs an engine treatment to clean up the sludge on valves so i paid to have them do that. Seemed to help so at the next oil change (5k) they said I needed to do it again. So I did. And agin it seemed to do better. But now it is real bad and smoking at every stop light I stop at. I just put some treatment of stop smoke to see if i can just get by for a little bit longer. I owe 16,700 on the car still and planned on keeping it forever since I love it to death. I am not sure what to do at this point. I just put a new battey and two tires and a oil change last week and that was a thousand dollars. It really burns me that I spent this much money on a car and followed all the recommened maintenance and to be told I need a new engine at 150,000. This engine should go another 100k easily. NADA says rough trade in is less than 9k. Engine runs good and sounds good. AND I will have to take an emissions test in about a year and my check engine light says high emissions right now. Any experience with this issue or recomendations are greatly appericated.

Have you considered and priced a top engine overhaul? Or at the very least, head gaskets replacement? You have excesssive oil consumption and oil migrating to your exhaust. That makes me suspect a cylinder head is compromised; either it is warped/cracked or you have a blown head gasket, or two.

Through all these, has anyone done a compression test on your engine at all? It may not be a be-all indication especially if the head gasket integrity is not compromised on the cylinder side, but maybe it will isolate the bank you need to concentrate on. Or you can find out if you have a fouled plug that can point you on the suspect bank. There are other ways like disconnecting the exhaust pipes and that can be an option to see which bank is causing your "smoke".

Agree that it appears you have a leaky gasket and oil is getting into the cylinders. This is not uncommon in cars with high miles.
I discussed this with my mechanic for my old 540 which I drove to 125,000 miles. He said it was a fairly extensive job but cautioned I would most likely have to do it if I kept the car any longer.
I would go to a different shop and get a full diagnosis and estimate. Go from there.

Does it smoke under the hood, or out the tailpipe? Very different sets of issues to check for. I'd look for a qualified indy bmw mechanic and follow nubi's advice.

Nube1 has made a good suggestion. But I am not sure it is worth going through repairs after repair.

My 04 545i is doing the same thing. Many 7 owners with same prob.They seem to agree it's the valve seals.Lubro Moly makes a oil stop leak that is actually suppose to be pretty good.Would not try anybody elses additives.There's a write up on the 7 forum for replacing seal with head on.

It only smokes from the tail pipe. Went to trade in and they are offering me 5k for it. It's does not seem to smoke in the morning or after work. It's when it's been driven for at least 20 minutes and I come to a stop or idle. Traffic in the morning is the worst. I have talked to the BMW mechanic who is my girlfriends cousin. He says valve seals seem to be the case. He is telling me minimum probably 5 k to fix. I cannot figure out what to do. I don't think if I fixed it at BMW I would even get a decent trade in price anyway and still be upside down 5 or 6 thousand. Then what's next? Will something be wrong with the emission's system that requires more work (high emissions check engine light is on). I have a feeling once BMW tears into it I become an open checkbook for them.

Has your mechanic ruled out the crankcase venting system? If not I suggest he use a boroscope to check for oil in the intake manifold. Shouldn't require any engine disassembly beyond opening up the air filter housing to perform this diagnosis

I had the same problem no smoke but the high emission light on. It was the gasket seal. Warranty covered it. At BMW it is probably going to be around 2 grand to change. Better of find a good Indy BMW mechanic to do this job.
Also high emission light does not really mean you have a problem with emissions it could be anything. When my ignition coil failed the same light went on

Exactly the problem,smoke after setting idle on take off or revving .Most likely exhuast valve stem seals.Can check CCV on top of valve cover for rips in rubber.I have seen this on many BMW 4.4.Heavier oil like 0w-40 with additive can help.Mine loses a qt.of oil every 2500 but runs great.I'm going to tackle the seals next spring.

I couldnt take it any more and was worried this was going to cost a arm and a leg, I traded it for a 2012 hyundia sonata limited. No more bmw worries for now on. I will miss it dearly but having to take xanex due to possible repair bills is not worth it. Maybe 5 years I will be in a better position to go back. Thanks again for the responses.

Sounds like you made the right move for you. A 7 year old BMW can be a $ pit and it seems you found a way out of the pit before you sunk too deep.

Sorry to go back to the topic of the smoke ------- Could it be caused by the 15000 oil change interval, or low octane gas?

Stealer told me it is normal for the engine to burn 1 quart between oil changes, and that is why BMW even sells a nice leatherette pouch for the quart oil bottle. Make sense???

This is a disturbing mail. Don't ever run on low octane gas. Min 91 required.
Don't go 15,000 miles between oil changes. I do it every 5,000.

The car should not burn oil like that, but if you mistreat the car then it will suffer and underperform.

Stealer is making up fairy tales. Find a good indie for this sort of stuff.

When I tried to take my car in with 12k miles after last oil change my BMW service advisor told me to come back at 15k. When it was under maintenance BMW wouldn't cover the oil change unless it was close to 15k. I always put premium fuel in but would t see how if I did t put it in it would cause it to burn oil

This is why the 15k OCI will do in the long run, wear down rings and seals. Sludge biuld up clogs oil passage and not getting enough oil to the moving component. Why toyota honda and such last long? Because they stick to thier 3k miles change. Everytime you start and stop you engine , moisture builds up over night. Everytime you drive you have fuel seeping through cyclinder walls and mixing with oil which degrades lubricant.

Dont wait til 15k. F**K BMW service recommendation. As I first hand see what came out.

Well even my hyundai sonata says 7500 miles. Oil changes have been every 3k for as long as I remember. You would think with all the technology put I to these cars no days that we can't go 10 or 15k without adverse effects. If I could go back in time I would gladly changed it every 3 or 5 k. But if you change at that rate do you really need to be putting in the full sythentic

Well Im not saying changing it every 3k , maybe around 7 is good. Some people dont even drive 15k a year. So oil is sitting in there for over a year. Try put a cup of oil in your garage for a year and let it exposed to moisture. Even though its not used it will turn black and turdy.

Same valve stem seal problem here. The car puffs out smoke after a long idle. I chose not to replace the seals and stick with a cheaper approach considering the age and mileage of the car. I did change a few things that improved the smoking.

2004 545i 165k Miles.

The car starting having the valve problems at 140K miles. I have been driving the car for the past 1.5 years (25K miles) like this with no problems other than minor smoking.

Actions Taken:
Switched oil from Mobil1 Full SYN 5W X 30 to Mobil1 Full SYN High Mileage 10W X 40
Started adding (2) bottles of Full SYN Lucas Oil Treatment at every oil change
Switched oil change intervals from 10K to 7K

Result:
Estimated 75% reduction in smoking


If you live in an area where you need to pass an emissions test you should change your oil prior to the test as the smoking in drastically reduced right after an oil change.
