Which is cheaper valve stem replacement or new engine for BMW 750LI

how many miles to you have on this buggy? more than 250,000....well that would make sense, if the interior is excellent yet and the paint's still okay would price out one from Yahoo motors 'cause they take into account mileage and let you comparison shop, so if at 2006 is what you've got could look for other 2006's to see if yours compares, and possibly ring this one up and by another one that had it's oil changes on time~

This auto has 133,000 miles on it. Bought it from a friend for $8,000 cash. I knew of some of the issues the car had and figured getting those fixed I would have a nice second car. This is by far the most costly. It's a shame because the car looks great for its age and mileage.

dang it Southern, you have to have it fixed, if this is the case, so often there are disreputable characters in the repair business...if you could find a "word of mouth" friend who has something like one of these and knows the shop to have the major stuff done, this sounds like a cut- and-dry major service, perhaps we will not know until it's stripped apart...maybe only a few components need replacement...you don't want a shop that wants to go "Whole Hog" on you~ please note the thin-ness of your credit card before assessing the job~ get someone who's creatively simple about stuff, not replacing things that don't need replacement and has the smarts to tell you so~

wouldn't it be something if it were a simple oil return port that had an obstruction...a candy wrapper, a soda lid or something got sucked into and is now an obstruction, could be removed with a tweezers....that would be nice~

How much oil do you add between changes?

Just bought this auto at a cash price. From what I see its still full of oil, and from underneath it is not leaking either. It has only been driven a couple hundred miles since I purchased. I had it checked out and along with the valve stem they found transmission pan leak, both upper timing case gaskets, alternator housing gasket. I guess that's why I paid only $8000 for the car.

Good question on the oil consumption. It could be more cost effective to drop in a quart of oil every so often than rebuild. I'm a little concerned with the white smoke. I've always heard of blue smoke from oil burning. White smoke from coolant... You know best, you are the one topping it off.

tenspeed has the right answer. Listen to him. If you spend that kind of money on the engine, you are going to have to drive it for many years to get your money back out of it.

a headgasket can be mended, let's hope it's not cracking of the cast parts~

Thank you all for your responses. This is my first experience with BMW's. This is a beautiful car and I just want to be able to enjoy it.

Hey i jus gt the 08 750li and thr guy at the dealer told me tht 02 thru 07 was hving a problem smoking and over the years n BMW was trying to fix this problem. He told me the 08 suppose the be the year they finally work it out so will i have that problem with my car it has 72941 miles on it. And also i gt 2 year extended warranty on the motor.

I have a 2006 BMW 750i. Bought it new. It now has 144,000 miles on it. At around 130,000 miles, the car would smoke from the tailpipe whenever I was stopped at a light, or in a long line (like at a tollbooth). I tried oil additives. I was putting in oil every 300-500 miles. And you could actually smell burning oil when outside the car. Finally, dealer told me I needed valve stem seals and quoted me a price of $9,700.00. I thought that seemed high. The overall condition of my car is excellent, and the car has been well cared for, with mostly highway miles. So I looked at the cost of a new 750i ($95,000.00), considered that my youngest child has not finished her education (she's in law school $49,000 annually) and decided to get the repair. Dealer reduced the quoted price to $7,400.00. I agreed and just got the car out of the shop 2 days ago. Wow. Its like driving a brand new car. The engine compression has been restored, with no smoking, and the car accelerates like a rocket. Its a major repair so I felt more comfortable with the dealer performing the service. Considering its basically an upper engine rebuild, the cost seemed reasonable. Now I feel that I'll get 200,000 miles out of the car. But no more V-8s. That smoking problem mostly plagues V8s. My next car will be the BMW 535 diesel. Diesel engines easily get several hundred thousand miles.

I can do this job for $2800. The dealership is waaaaay overpriced and they do it the easy way without pulling the engine. The reason it cost so much is because they charge you over $4,000 for the labor alone. The engine is supposed to be pulled and the heads pulled off to do the valve stem seals, but you don't have to.

Hi James. I have 07 750li and it needs valve stem seals. So you could do the job for $2800? Which city are you In?

James I have a 2007 750Li and I seem to have the same problem. Are you located in the NYC area?

Then there was Silence. LOL. I have the same problem. If this guy is serious and qualified, drop me an email at Waco_game@yahoo.com

Even if you purchase another engine there is no guarantee you won't have the same problem eventually. I just put cash towards a new 2014..

Thanks Southernjag93 ; however, Im purchased this vehicle as an investment, to buy and resale. I need to get it in good condition and sell it. But again, thanks for the response. I can get an used engine with 76k miles for only $2700. Although, I bet the labor for an engine replacement its not cheap. It may be comparable. Plus, i would have the old engine which would be worth a little bit. Hummmm...

I'm located in Texas and I was quoted around $4000 for labor on and engine install. Good luck..

Im in Waco, Texas. What a coincidence!! Okay. Have a good night!

I'm in Georgia in the Atlanta area. I don't get on here much. I can still do the valve stem seals if you would like. My email is veritas579@yahoo.com

I have a similar problem with my car. Any mechanic I'm dc/va area to do this work cheaper than dealer.

I have a 750li

I am in Virginia. I need someone to fix valve stem seal on 760li . Please contact me marielngem@gmail.com.

I'm in Milwaukee area. Need valve stems covers for BMW 750li. hurricanesexxy@gmail.com

James I emailed you. I am also in Atlanta. Can you reply to my email

I AM IN THE NORFOLK VA AREA AND I AN THINKING OF BUYING THE KIT AND DOING THE SEALS MYSELF. ANYONE ELSE NEED THIS DONE WANT TO GO HALF ON THE KIT?

I possibly would. But, I sold my BMW. Was tired of fooling with it.... I dont see way a vehicle that cost so much should have such a common problem thats so costly

Hey ken, what kit are you referring to

Hey James, I emailed you also cause I'm having the same problem and wanted you to look at my BMW I have an 07 with 115,000 and I need valve stem seals they quoted me 5,500. Seeing that you can do it way cheaper would be great! Please email me and let me know tyanna_r@yahoo.com

Hi James I emailed regarding 04 745LI white smoke from tail pipe would like for you to repair. Please contact me @ tahara_jones@yahoo.com thanks in advance.

JAMES auto zone told me that a metal waterhose that goes with the valve stem job is worth about $1,300 ... Is that true?

Miguel. I am not sure what water hose your are referring to. There is a water pipe that runs from the front of the engine to the back underneath the intake manifold. It is very labor intensive to replace unless you use the two piece aftermarket pipe. I don't see why it would be included in a valve stem seal job.

In Cleveland Ohio can someone please fix my valve !!!! quoted me 6100.00

Anyone knows of a repair person in the Southern California area..? Please let me know. Fullert650@yahoo.com

I'm in Tampa fl can anyone help me

I have the same problem in my 05 745i needs help asap

Hello . . . I had a similar issue with my '06 750 - smoke upon start-up and during long idling times (such as at a toll booth). It got to the point I was adding two to three quarts of oil between oil changes. Figuring this was a valve seal problem, one of my mechanics suggested using a product called Lucas Oil Conditioner(I believe this was the name) hoping this was a "stuck" seal issue. After several quarts, we decided this was not the right product to use. Then I discovered that Lucas makes product called Engine Oil Stop Leak. I tried this product and my oil consumption stopped completely. Even after the next oil change, the oil level remained at the "full" mark for thousands of miles. I was ecstatic - but before I could monitor the car any longer, I traded it in for a newer vehicle. I am not suggesting this as a "cure-all" but for $12.00 it was worth a shot. In my case it paid off.

I have a mechanic that does this in SoCal if anyone has this problem. Charges about half what dealers charge. Email me if you need it. He's a BMW mechanic at a dealership in Irvine for the last 14 years.

Email me at adargham@gmail.com

agatools.com sells the tools to change the valve seals for $841.00. Look it up on YouTube on how to do the job. Don't take it to the stealership!

I've never heard of oi causing white smoke. White is caused by coolant but oil causes blue smoke. A car sitting at idle will tend to suck oil around the valve seals into the cylinder or cylinders. The oil burns resulting in blue smoke out the exhaust upon acceleration. White smoke is most often caused by coolant leaks into the cylinders from a bad head gasket. My observation is that a used BMW is like an Italian wife. When all is well, they are a delight. When things start going south, they are an expensive pain in the rear. A service rep at a local dealership told me he would never own a BMW that was out of warranty. You may afford the purchase but in time you won't be able to afford the upkeep. My choice these days is a Jap car. Not too plush but 100 percent reliable.

Hi Karl, I like the analogy of the Italian wife...LMAO. I have a 2008 750li that had the same issue of "white" smoke. I initially thought it was coolant, but it wasn't consuming coolant and there was no antifreeze odor coming out the tailpipe. I replaced the valve seals and no more smoke. I'm not sure why the smoke was white; perhaps the catylatic converters have something to do with it. Take a look at this YouTube video and let me know what you think; it even shows the white smoke. http://www.youtube.com/watch?v=YacOx2ydMbl&sns=em Or you can simply type N62 & N62-tu in the search field and it's the first video in the list. Also, I had Nissan Maxima (Jap car). Most unreliable vehicle I've ever owned. No vehicle is 100% reliable!

i am located in portsmouth va 23704 and thinking of buying the kit to do my valve stem seals. anyone local to me that wants to off set my cost by paying part and we can do your car too

Hi i am in Jacksonville fl and the BMW shop qouted me 3200 to do the vavle stem seals.....

I have 2011 and all they did was replace the EGR. It's from oil getting traped in the exhaust. Simple!

Does anyone have an feedback on just replacing the seals and not doing the complete head work?

Type N62 & N62-tu in the YouTube search field. Select the first video and read the comments. Many have changed only the seals, including myself. Valve guides weren't worn. No reason to pull the heads or remove the timing chain on my 750li.

Four months ago I wrote about the success I had using an oil additive in my '06 - 750i to combat oil loss. I now have a '12 - 750i that used a quart of oil between oil changes. I started using the Lucas Oil Stop in this vehicle. I had an oil change two weeks ago and added the oil stop before embarking on a 2000 trip. After the 2000 miles the level still shows "full." I hope this helps my '12 as it did my '06. Disclaimer: I do not endorse any product. I am only letting you know what has worked for me up until this point.

While I have used additives in the past in some of my cars, Slick 50 in Chevies, I struggle to add anything to my oil for the bmw. I have increased the oil viscosity to 0-40w and the smoking has stopped, at least for the first 2 days so far. I guess the question is how worn do the valve guides need to be to warrant the head removal versus just replacing the seals.

oh and btw the 750Li only has 115k miles on it.

Changed the seals in my 750Li at 99k.

just the seals? no issues with the valve guides?

That's correct, no issues with the valve guides.

Lucas oil stop leak definitely works. I just added it a week ago no more oil burning or oil smell. Hope this also solves the little white smoke and smell I was getting from the tailpipe while sitting still for a while.

Btw...I have 06 750 Li

Have same problem...guess I will try the stop leak first

I will try the lucas stop oil leak too in my 2008 Alpina B7(750 LI) 500 HP Engine. I hope the lucas stop oil leak doesnt mess up my engine.

Part of the issue with oil leaks is because when they were sold new; the maintenance schedule for oil change was every 15,000 miles (wow) because they believe their engine is foolproof. Unfortunately, they were putting in 0 - 30 grade motor oil, which are thin oil as compared to 10 - 40. 0 - 30 grade oil will not last 15,000 miles because thin is good for easier cold weather starting and reducing friction, while thick is better for maintaining film strength and oil pressure at high temperatures and loads. (They're V8s not a 4 cylinder engines). Consequently the gaskets and seals dried up due to their maintenance schedule. BMW knew they made a mistake in choosing the wrong grade of motor oil but they didn't want it known because of the liability issues. this information was given to me by a highly respected German mechanic.

Seven_7911 what other l should I use ? I live in cali cold in morning mid in days.. have white smoke after idle and don't have the cash to replace stems . Should I use a liquid sealing solution? Plz help

I picked up a gorgeous 2008 750 Li with 72K miles on it from a "used car dealer". I was the third owner and it was previously sold a Certified Used car. I thought all was good. Turns out the '06-'13 range is known to have engine oil leaks. I guess this is the nature of the beast. I did shop around the Boise area and found the Dealer to be twice as expensive. I ended up at Boise European Motors and they fixed the Upper Timing Covers and the Alternator Mounting Bracket and Cooling was leaking severely. By that I mean 2-3 qts every 2K miles. Lots of oil on the garage floor kind of leak. That was $2,700 to repair both of those. Again the dealer wanted 2x that cost. Now at 80,000 I am burning 1 qt of oil with absolutely zero engine leaks. A little bit of blue smoke comes out when it starts and my mechanic confirms the Valve Seals are starting to fail. Seems like BMW has had enough issues that they should do something. Its a super fun car to drive and own. But BMW can mean Break My Wallet for a reason. If can afford to own a car like this go for it. Beware that it is expensive to operate.

Ken. Still looking to go half? I'm in vb.

I live in Chicago area and own a 2007 650i 86,000 miles my car has been running rough and I have I've added 3 quarts of oil in the last 2000 mile.

Ugh anyone in Chicago area that can do this for less? Please email me Lizdolan99@yahoo.com , thank you.

i have a bmw 2010 750i. 51000 miles. have to add a quart every 400 miles. No visible smoke. Can anybody help? I am in atlanta area.

2005 E60 545i - this car is piece of shit! Bought this car while still under 100k extended warranty with all "Dealer Service" records, which is bullshit. Dealers don't service these cars properly, recommended oil change every 10-15k miles. I've spent over $25k servicing this piece of shit including: Replace transmission due to lock up and surging and slow speed or stop sign, Brake booster failure causing collision. BMW later recalled this but wouldn't compensate me for my repairs because the BMW part numbers weren't legible on the receipt. Valve Stem seals leaking also causing secondary air intake valve and fuel tank valve failure. This repair is cost more than the retail value of my car, which is super clean! I'm so f'ing over BMW... will never buy another one after 20 years of being a loyal customer. Going with Audi next time.

I have 2007 BMW 750LI with 139,000 mille it has white or blue smoke and it needs Valve stem seal job found a guy in Orange county who will do it for $2,500 he said its a 27 hrs job. The dealer quoted me $8,000-$9,000 he said its a 44 hrs job. Can't trust anyone these days you just cant believe anyone. Sad times indeed. I am thinking of getting it done for $2,500 but worried that other things will go wrong as I hear the transmission can go bad too. I purchased a new 528I twin turbo but I don't love it as much as I love the 750 ride. I hate BMW for not backing up their cars they ask for so much money for the cars but when they fail they don't want to be help accountable.

I believe BMW dealerships remove the engine and the heads, which would account for the added hours. Your guy that quoted $2500 most likely has the AGA tool kit, which means the seals can be replaced with the engine in the vehicle and without removing the heads.

I’m 45 minutes south of Birmingham Alabama and I have a 2007 750li that has oil leaks and smoking out the tail pipe and was also told that I need a valve stem job done, I was quoted $5000 - $5500 is there someone in this area that can give me a good price email me at blknmild44@yahoo.com my name is Alvin thanks in advance

A new engine could simply do nothing to solve the leak issue if both engines are affected. Mine was $2500. I did not go to the dealer and my mechanic had the kit which enables them to leave the engine in. Without the kit, you have to pull the engine and that is more expensive.

I can do the valve stem seals for $2000. Located in San Diego area. Email me at rick.james105@aol.com

AGA tools makes a valve stem tool that I purchased on Ebay used for $900 and replaced the valve stem seals with my mechanics help for $1800 US including the seals spark plugs valve cover seals upper and lower front seals and belts and water pump.

I meant to say that I sold it on ebay for $800 after I finished using it. No more smoke

Any Valve Stem repairman in the Richmond VA Area. My Can is not smoking but was told by dealer at last oil change that I need a complete valve stem repair.

Hi, if you can find a mechanic that is competent, you can buy the valve stem seal kit from AGA. After you have replaced the seals you can sell the kit on EBAY. You maybe able to purchased a used kit on ebay. The replacement seals are very cheap on ebay. I changed the seals and the upper and lower gaskets on the front covers as well as the valve cover gaskets and spark plugs and tubes, water pump belts and some hoses for about $1700 US including paying my mechanic. I am in Alberta Canada and I helped my mechanic remove parts and even changed some seals. It took about 16 hrs. I paid $1000 US for a new kit from AGA sold it on ebay for $900 US, it sold in 12 hrs. I bought all my parts on ebay. I will be doing the same job again in Jan or Feb 2020 on my 2007 750Li, as it will probably need it by then. I don't think you can replace the engine for less. Put an ad in your local news asking for a competent mechanic to work on your BMW. I go to companies that work on BMW, Audi, Mercedes that charge $130 per hr and do the job in less time than the dealers. You must have non dealership BMW mechanics in your area, get a quote, it should be less than $2000. Buy your own parts. If your car is not smoking you can use a Lucas additive that will help keep your car from smoking. How many miles and what model, year BMW Good luck, find a mechanic and get your hands dirty, it was a lot of fun. Anytime I get to work on my BMW I enjoy myself. Thanks Phil

On this page you can rent the AGA kit and they tell you what parts you need and how to do the job. Its the $0.99 rental. https://www.ebay.com/itm/Bmw-valve-stem-seals-kit-AGA-N62-VALVE-STEM-SEAL-KIT/253731323586?epid=1732967082&hash=item3b1390bec2:g:4uoAAOSwW1NayVCy Thanks Phil

I have a '12 750Li with 78k miles that blew smoke after idling. It didn't pass the smog check. The guy there told me to take it to BMW where they will fix it. I didn't believe him since the warranty expired a while ago. However, I had nothing to loose. They ran tests on it and said they would fix it at their cost! Turns out emissions issues are under a different warranty that varies depended on model. Mine needed the valve seals replaced, and that is covered under warranty. My service tech thought is was for approximately 10 years 120k miles for my 750Li, but he wasn't positive.
