Need Help..Turbo Seal? White smoke!/ Overheating

Hi everyone, I'm new to e90post forum as i just sold my E46 M3 and bought a 2007 335i.
I just noticed a couple days ago some smoke coming out of the exhaust that smells a little like oil burning. After doing a little research i believe my turbo seals are going bad. I was wondering how much do they cost?
is this fixable or i would have to get a new turbo? Any help would be appreciated.

Lots and lots of info on this forum about turbo problems with your model. Feel free to read until your hearts content. But the short answer is bring it to the dealer. You might still have a warrantably repair.

Thanks, I am sure that i'm out of warranty already. But i have been looking to find out if turbo seal can be changed or fixed or if this is a sign for the turbo going bad.
I also noticed that the oil level went down as i got an oil change a month ago!

If you have any wastegate rattle, you could potentially have them replaced for free as long as you're under 8 years/82k miles. There is a long thread (one of many) on the subject.

Anyone know if there is a rebuild kit for these turbos? New seals, bearings, etc.

Do you have more than 82K on the car? If not, do yourself a favor and take it to the dealer.

People keep using 82k as the turvo warranty period which is incorrect. That is only if the dealership finds significant play in the wastegates. So if there is a failure that happens that would be covered under the regular warranty period it doesn't mean its covered under the wastegate extension.

Wouldn't white smoke be coolant burning? I believe smoke from oil should have a bluish tint to it.

It was some kind of heavy white smoke that smelled like oil burn. I check the coolant frequently but the oil level keeps going down so that means I have oil that's getting lost and burnt.

The smell will give it away, coolant will have a sweet smell to it, oil just smells like combustion and well...oil. The white smoke that can signify coolant burn off is a starch white, a white-greyish "smoke" tinted smoke can def. be oil. My car does the same thing, i'm quite certain at this point it's my turbo seals. They don't pour smoke or anything like that, so i'll live with it until I purchase Stg2 snails or the OE frames stop building boost.

If it's the turbo seals. Is that an easy fix? Around how much would it cost to change the seal?

if it's your seals, you need new turbos to fix the underlying issue. So not cheap, due mostly to labor time. I wouldn't jump to the conclusion that it's your turbo seals though, N54s leak/burn oil from numerous places

I just went under the car and checked for any oil leak and couldn't find anything. Went to add 1 quart of oil. Now I have no idea where this oil is going. It shouldn't be normal to burn 1 quart every month.

You are burning the oil. So you would not necessarily see a leak.

Also, regarding the warranty. I don't think anyone said his problem "would" be covered, merely that it is prudent to take it to the dealer and check.

Your actual motor could be burning oil too, it might not be the turbos. Get it looked at by a professional.

+1 I was about to say this. Your lowered oil levels might be from the motor burning the oil.

People with the N54 whenever they start to see smoke, jump to the conclusion right away that it's their turbos. In most cases it isn't, and can be from valve stem seals, faulty PCV, super-dirty intake tract, piston rings, valve cover, etc. To rule out the turbos, drop your downpipes and take a look at the turbine wheels. If you note any liquid oil then it's your turbos.

Some education here on turbo seals. The seals are actually more like large snap rings which when positioned correctly (open area up) don't blow oil into the intake and exhaust. Rebuilding the turbos is a very labor intensive project which is why most just replace them with rebuild or remanufactured turbos.

If this was my 335 I would be checking the intake to be sure you are not blowing oil into the intake which does happen under both boost and under vacuum. BMW doesn't have the most robust PCV system and many times it is leaking. Thus don't think it is just the turbos (which is very possible by the way) or as mentioned previously other engine oil causes.

Be cautious about what the dealer says. Many times they are looking to remove and replace. I have had great success with one dealer and OK success with another. Post what they tell you. You can if you can afford the downtime send your turbos off for a rebuild and they will provide you with like new turbos that are much cheaper than removing and replacing. If you do buy new turbos try Tischer BMW at getbmwparts.com as they are one of the cheapest dealer parts supplier out there.

Thanks a lot for all of this good info!

Just an update guys. I was driving my car today and all sudden the fan started working and the car was over heating! I parked and as soon as I parked the red temperature symbol came on. I had to tow the car back and now it's sitting in my garage.
I have no idea what is going on now it is really confusing. Anyone think those two things are related or was it just a coincidence?

I hope I am wrong, but it is possible, but not likely you have a cracked block. The next thing to do is to look at your radiator fluid. Is it contaminated? Is it low? If the answer to either of these questions is yes, then you may be in trouble. Keep in mind that radiator fluid gets pretty yucky over time. So don't be alarmed if it is a dark color. The main thing to look for is 2 different liquids that might swirl, but not combine. Oil and Radiator fluid will not mix. Also, since your radiator is a closed system, you should not lose any noticeable amount of fluid, ever.

Here is a website that can help you understand the signs of a cracked block.
