Valve stem seals done for $2500!

For those who don't know me.... I'm a BMW master tech located in Long Island, NY who has helped out many forum members here in the past (just do a search and you'll find me). I've been seeing many posts about the common valve stem seal issue with the N62 and N62TU engine. Symptoms include excessive oil consumption and severe smoking from the tail pipe. I'm offering to complete the repair for $2500 total (parts and labor). This includes new valve cover gaskets, new upper timing case cover gaskets and valve stem seals of course. I would need 2 full days to complete the repair, I'm available on weekends (I work at the dealer during the week). Most dealers charge anywhere from $8,000 to $12,000 to have this done, so here's your chance to save a ton of cash! I've had someone drive over 12 hrs to meet me and to have the repair done, it was well worth it for that customer. You guys can post here or PM me. I'm also a forum regional sponsor, so my contact info is located in the section of the forum. Thanks!

How can I be certain if my intermittent smoke and excessive oil consumption is the seals or the oil seperator issue?

The correct way is to measure crankcase pressure, But the cost of diagnosis might be more than the cost to replace the CCV rubber diaphragms and vent tubes. Those components are easily accessible and can be ruled out easily.

Here's a pic of the last stem seal job I did, you can clearly see the difference between the old and new sealAttachment 374829

ever get a P0300 after putting it all back together.... cant figure out where im getting the error from, i checked and double checked all the vacuum hoses, and I even changed out that small tube from the intake elbow..... thru the wire harness case, to the fuel filter pipe... I guess i will need to d oa smoke test, unless you have any other ideas....

blinking red ses light, really rough idle, but if you rev it up, is smoothens out, but you still get the blinking ses light thru out... i wont keep it on for more then a minute, dont want to burn the cat out..... you can smell unburned gasoline thru the exhaust, so its a lean condition....

tried a bottle of Heet, that didnt do anything...

Are you sure the timing is spot on? Are the Vanos solenoids fully seated? Are any connectors swapped?

Timing I now spot on on the left side the exhaust was off by 1.75 mm with the tool.... I could stick a quarter but not a nickel in the gap... Fixes that issue, even used a new sprocket bolt.

Are the solenoids seated, yes. Pushed and rotated them in all the way, looking with the vc removed the o-ring was seated and you could see a tiny gap between the green body of the solenoid and the cylinder head... Couldn't get it to move any more....

I doubt I could have bent valves if I ha it off by that little when I timed it... But I think it would throw specific cylinders not the general P0300, if it was bent valves

When you removed the intake cams, did you have the engine in TDC? If not, the intermediate levers may have popped off the springs

It was locked in TDC.

I even turned the engine 2 revolutions and re locked it to TDC and timing was dead on, no gap at all.

First off $2500 for the job is a steal! Anyone within a 100 mile radius needs to jump on this deal!

Okay, let me tell you were I stand. I put it all together and got a single misfire... Cylinder 5.... Realized I knocked off a lever... So I took the vc off and fixed it put it all back together, and am now getting a random misfire, inpa says it's a pending misfire of cylinders 1-4 and I'm getting the flashing red SES light (so no fuel cut off)

Things I have checked fuel pressure , it's fine

Ccv valves - fine

Vacuum hoses all fine

Disconnect valvetronic - same condition

Switched coil packs side to side
Inspected spark plugs.... All were okay.

I'm not getting a timing error, could I have lost timing somehow? I reset adaptations in inpa too.... I really don't want to pull another vc off but that's the path I'm heading towards unless you can point me in a different direction.

How was the car running before you started the whole job? When you the knocked off cylinder #5 lever, how were the other cylinders? Did you work on one bank at a time or did you have both valve covers off at once? It is possible to have 1 bank off 180 degrees (both cams) and the engine will still start (I've seen it several times). Bank #1 has to have cylinder 1 lobes facing each other and bank #2 has to have cylinder #5 lobes facing away from each other.

It ran fine before... Just the usual smoke issue. If I remember correctly bank 1 was clocked at 45 degrees exhaust, and 315 degrees intake ( pointing toward each other... And bank 2 had the pointing away from each other... I guess the only way to verify is by opening it up.... I think I saved pictures on my computer, I'll check later on... Originally I had both cc's off at the same time, but since then, only worked on bank 2 (5-8, driver side)

I'm just surprised that it ran fine before and now it's misfiring...

Sorry for the double post.... I've seen people make this mistake when they do only one side. It's hard to say without having the car in person, but I would say you should remove both valve covers and double check everything.

Took the vc off, checked timing, the intake was out 180 degree's... I'll fix it tomorrow... Big question is, if there is any valve damage.... Ill do compression checks on each cylinder, before closing it up...

Valve Stem seals done for $2,500

For only $2,500!! I'd gladly pay that if bmwoem1 was out west in Los Angeles, CA!

bmwoem1, is it possible for you to post a detailed DYI for the Bimmerfest community?

Not trying to take away your gigs, but some of us DIYers can do the valve stem replacement; however, we would need your detailed expertise in setting the engine timing from start to finish.

I have 3 weeks vacation in June and would like to do my 6er and post a DIY for the community, but setting the timing would be my concern.

Any help is appreciated, buddy! Thanks.

Timing is the easy part if you have the tools. They cost about $425.

I'm really trying to avoid messing with the engine timing.

I saw a DIY of a fellow replace the engine valve stems without removing the camshafts or the engine head with a valve spring tool and a piece of rope on the V12 E32.

http://bmwe32.masscom.net/sean750/Va...eplacement.htm

Just trying to get a DIY to help the entire N62 6er community, like the one on link above.

Any of you think that this is possible or would the camshaft assembly get it the way on the N62 engine?

I may be able to tell you how keif has a good post with pictures if what you need. You need the timing tool and the spring compressor kit. (Only 1 kit is known to work) everything else's is pretty easy, barring you run into small issues like u did, trouble shooting is tough.... I'll write one up, and include some pics... Maybe make a PDF or something
