Oil consumption was excessive - It smoked - I was told I needed valve stem seals

My car (didn't pass smog & couldn't renew registration);
2006 BMW 550I – 92,000 miles – V8 (N62TU)
Smokes (white/gray/blue) – failed visual – Smog Report (15 mph – HC ppm Measured 91 – Max. 49)

Symptoms & history;
It used oil (approx. 1 qt. per 2-3 tanks) and I read the history of V8 valve stem problems (internet & local shop research), I was about to have the valve guide/stem seals replaced or drive the car off a cliff. But it didn’t have the classic symptoms of defective valve stem seals/guides. It also ran like a rapped ape (old school for ran great). I’m a heavy truck mechanic with old school car experience (35 years). The plugs were clean and the exhaust smelled funny, also the exhaust dripped clean water no matter how hot or long it ran. I pulled the intake throttle housing and noticed excessive oil. Replaced the (ccv) diaphragms in the valve covers (torn) & read up on the cyclone oil separator (like a Dyson vacuum). Because I wasn’t happy with the oil consumption & residue in the intake, I fabricated a Scotch Brite pad filter with screen for each valve cover vent outlet. As well as a pre-filter for the CCV diaphragm base. This cleaned out the oil residue and has greatly reduced oil consumption while allowing crankcase recirculation. I pulled the spark plugs and stuck a camera down a couple plug holes. Yes, the top of the pistons were loaded with carbon. So I sprayed Sea Foam in each plug hole, followed by a shot of low pressure shop air to help spread it around the piston. I let it sit for an hour or so, then reinstalled the plugs. I topped off the fuel tank with high octane and added 12 oz. of CRC Fuel System Cleaner (part #05063) to the tank. 100 miles later and what a difference – no smoke or water dipping out the exhaust after warm up.

****This note was copied from a BMW Technical Training manual
Note: If the exhaust system produces blue smoke, it is necessary to check whether the engine is also drawing oil into the combustion chamber through the crankcase breather, which suggest that there is a fault in the area of the crankcase breather. A clear sign of a problem is an oiled up clean-air pipe.

****The Variable Intake Manifold acts like a giant catch can. Pull the Intake Throttle and suck out any oil that may have accumulated in the base.

****The valve stem diameter was increase at a production point (you would assume) to remedy the guide problem. I don't believe BMW would use inferior stem seals after this change, if ever. My vehicle has now passed smog test & no longer smokes. I did have to run the proceedure twice before it lowerd the HC levels within specs. I will use the Chevron fuel treatment from this point on. (See attached TSB) It cost me $200 to fix compared to the $4000 > $5000 I was told it would take for a guide/seal replacement.
SI B 13 05 06 & SI B 13 01 07

**** Day 50 - 1500+ miles later NO smoke or excessive water from tailpipe - It also only used 1/2 qt. oil **** I changed to a 5w-40 synthetic
For those of you seasoned mechanics replacing guides & seals - This worked for me - my vehicle - my situation - but I believe you should diagnose each vehicle on an individual basis - Regardless of BMW guide/valve stem history.

First, help us help you better by creating a signature that includes your model/model year/build date. You're asking a question that is engine related and the only info we have is that you have an 06 X5...which could be 1 of 3 engines in the USA/Canada or 1 of 4 engines internationally (3.0i/3.0d/4.4i/4.8is). That way the forum can respond specifically to which engine/transmission or other of the many changes that occured during the production run from 1999-2006.

It also helps forum members in the future if they come across any of your posts while searching the forum for information...they will know immediately if your problem/diagnosis/solution/resolution applies to their application since they can see at a glance what model/model year/build date your X5 is. You can click the USER CP link at the top left of the page then look for the EDIT SIGNATURE link.

Have you checked your CCV/OSV membrane thingy? See the video below to see if the symptoms seen in the video is what you're experiencing.

The video is about the M60/M62/M62TU engines...the N62 can suffer from the same symptoms except the membrane is in a MUCH easier location...and BMW sells repair kits for the N62:



You can see in the diagram below (if you have the N62b44 or N62b48 engine) that the OSV/CCV membrane is located on top & not on the backside (see #13):



EDIT: oops...just reread your orig post and see that you're posting from a mobile app...which might mean that creating a signature may be different. If so, then try to remember to type in details about "which" X5 you own...again, the solution to a problem is not all the same for every X5...there's differences based on engines/transmissions/build dates etc.

Qsilver that video is right on point! Those are The symptoms. This is my first Bimmer, I'm getting familiar with it. I'm going to do as you told me, as far as putting more info about my 2006 bmw x5 4.4i 8cylinder.

Thanks A B ABLE! This really helped me out. Well, I'm gonna do the work my self. Is there any pointers on changing the CCV? I'm going to change the spark plugs as well, I have a feeling there probably soaked with oil..could be wrong though. It runs rough at start up during the am hours.

My spark plugs looked clean - it was the carbon buildup on the pistons
(Had to spray Sea Foam thru plug holes and let soak - See details on previous post)

Unless someone replaced your N62 engine with an older M62TU engine...the OSV/CCV membrane you saw Edwin replace in the video is located on top of the N62 engine (see #13 in the engine diagram above) which is in the 2004-06 N62b44 & N62b48 engines (4.4i & 4.8is).

For those that have the M62TU engine...Edwin's video makes the job a whole lot simpler versus removing the entire cover (#2 in diagram below) off the back side of the engine (intake manifold)

(#2 cover @ back of intake manifold that houses the orange membrane - on the M62TU engine {2000-03 4.4i & 4.6is})

-


(the orange membrane is incorporated into the cover #2 in diagram below)


Again, this membrane that ruptures and causes the smoking at start-up or idle has been moved to the top of the cylinder heads on the 2004-06 N62 engines (4.4i & 4.8is)...and is #13 in the diagram below:

(#13 (repair kit) for the N62 engines)
-




(see #13 in diagram below)

Hope this makes sense.

Re: Smoke Coming Out of tailpipe

Qsilver I want to upload a picture of my motor, to make sure. I pulled those two caps off the sides to look at them & they look ok. No splits or cracks in either one. I'm very mechanically inclined, but my first time on a bimmer

Replaced ccv, separator & all hoses..... Still smokes

Curious,

I have a BMW X5 m62 and it started smoking like crazy which I automatically assumed was the CCV or hoses, so I replaced them all plus the separator and bottom hose, so all hoses are now replaced, CCV and separator, and it is much improved, but it still smokes when warmed up for about 15 minutes of driving below 2500K RPM. This is consistent, no smoke when idling for several minutes and no smoke on first acceleration, only time I see smoke start is after 15 minutes of driving. I have repeated this several times and it is almost to the minute each time. I thought it might be residual oil in intake since it was pulling so much oil into intake before replacing everything.

Just so you know, I change oil every 5K to 7500K with 10-30 Mobile 1, so the CCV valve was clean and not fractured or leaking. But what I did see was the top two hoses going to separator were sucked in and soft, plus when I removed them, they were partially clogged with sludge. so I believe that was where the problem was based on research. So I replaced everything knowing how difficult it was to get to all these hoses and screws for CCV. So my question is, how much oil could have gotten into the intake manifold to still smoke when warned up, not a lot of smoke, but enough to notice. Funny thing is, when I stop and turn off motor, and wait five minutes, it won't smoke when I start it or start driving again. The same 15 minutes, so it has nothing to do with warm up time, but it does seem to be a time factor more than engine temperature issue. Anyone have an idea what could cause this. I have driven about 70 miles and still smokes.

Thanks,
