I just rolled past 200k the other night in the 540i, also just ordered and received the Besian Systems Vanos repair kit for the V8 Vanos'. I am literally so tired of this car sounding like a freaking Russian Tractor on a frigid Siberian morning when I pull up to a stoplight in traffic. I am sure folks look at our cars with the rackety sounding Vanos and wonder WTF!?

I will tackle this repair in the next couple weeks and will report back to folks how it went, and if the noise subsides with the repair. That THUCK, THUCK, THUCK vanos sound is annoying as hell, and for a luxury sedan to make such a noise is embarrassing.

I did the timing chain guides, and all the other associated vanos specific repairs (minus any actual vanos wheel work) outlined in the Besian documents in early 2012 and have be waiting for Besian to work out the kinks in their Vanos repair process. Now that the V8 kit is available I'm hopeful the noise will disappear.

Wish me luck...

Good luck. I'm hoping to tackle this job as well. I'm in the process of saving for all the parts like valley pan gasket, timing chain tensioner, valve cover gaskets and anything else I'll need. Let me know how it goes.

I have 295,000 and haven't done any vanos repairs...yet. I also have that thuck thuck noise. I thought the timing chain guide rails would have fixed that. I did them a year ago and it still sounds the same so it looks like I'll be doing a vanos repair soon too. I get asked often enough about the "rod knock" that I have come up with the explanation that it is normal and has been doing it for years! I'm really curious as to how hard the job is and if it restores power too. Good luck!

Finally Done!!

Ok guys, I purchased the Besian Vanos repair kit for my M62TU motor in middle December. I had a spare pair of Vanos wheels on the workbench and I did the repair per Besian guidelines. I also purchased an extra Teflon seal per Besian suggestions and I'm glad I did. The first o-ring and Teflon seal went in without a hitch, no wrinkles and had it done in 5 minutes. The second o-ring went in easy but the Teflon seal fought me every step of the way and I wasn't happy with the final install of that seal. I removed it and installed the third Teflon seal and that one went in just as easily as the first. Go figure....

Those Vanos wheels sat on the workbench until Thursday of this week when I finally had time to tear into the motor. I own the timing tools so at least i didnt have to wrangle those tools from anyone. For anyone that has done this repair, it's not difficult, it's just time consuming as hell since you have to remove/reinstall so much stuff. This is the third time I have timed the car and it again came off without a hitch. Car runs great and no codes so far.

Now to the sound...*****, I can't recall the last time this car was this quite!! No more russian tractor sound, and I can now pull up next to a drive up window and not be embarrassed that a luxury sport sedan sounds like its about to rattle apart. Low end power has returned!! I haven't driven it super hard yet, as I always give the repair a couple days to make sure I didn't screw something up and it rears its ugly head. I would rather have something happen at low speed than at wide open, high rev shifts when something lets go.. So far I am one happy camper with the repair. I have a week of driving ahead so I hope to report back at the end of this week with a follow up.

If you need to do this job, get with it. You won't be disappointed! I took the top end apart on Thursday evening and started again at 10am Friday morning and was totally done by 3pm Friday afternoon. I take my time so I don't stress nor rush and screw something up.

Ok, you may have convinced me to attempt it, although once it's warmer out.

That's strange. I thought VANOS was not a worry on our V8's. My engine has 184k miles on it and it's relatively quiet at idle. Are you referring to a thud/knocking noise at start-up or during idle?

thanks!

Mine hasn't been done and I'm close to 300,000 mi. but it probably could have used servicing at 150,000 mi.

Don't have the v8 vanos but I have a 6 cylinder vanos just starting to make noise at 253,000

Is that the original engine with that mileage? Auto or manual? If auto, original transmission?

Hey everyone. I have purchased my 1st BMW and its a 97 E39 540i 6speed. I'm kinda sure that I don't have Vanos on mines. It's in relatively ok shape but needs new paint job and in the process of doing an M5 clone to it. My question is can I/ should I add Vanos and if so is it worth it?

Btw lol looking to do a aluminum radiator with fan shroud to upgrade the cooling. Essentially I'm overhauling the car this year. I would like to supercharge it eventually but not sure if ok on 184k engine with old parts inside... Suggestions welcomed!

V8 m62tu

If you have the M62TU motor then you have Vanos. It's my understanding that 97-99 V8's did not have Vanos. Late 99 build dates, and those listed as 2000 model year V8's and beyond have the Vanos. You will get the rattle at startup, and at idle your car sounds like a tractor.

To each his own on performing the repair. These cars are supposed to be quiet at idle and startup, so what you choose to accept in the sound and performance of your car is for you to decide. I literally could not take the sound any longer. My car is now quiet once again, and the low end performance is back.

As the Teflon seals within the Vanos ages and losses its ability to retain the oil behind that Teflon seal, your variable valve timing degrades and is off slightly from what it should be. this in turn degrades your low end power, and also how the timing reacts to throttle demands. Since this Teflon aging happens over time, we as drivers don't notice the subtle degradation in power and become used to how our cars respond. Once the Vanos have been repaired, you will notice the difference. I have put 200 miles on the car since the repair and I couldn't be happier with the results.

This repair is straight forward if you have the timing tools, etc. (I own the timing tools) But if you're one of those guys that should never ever approach a car with a screwdriver in your hand, i.e. not mechanically inclined, you may want to seek out help from someone on the board that is local to you. I'm in Frisco Texas, DFW area, so if your local I am a resource for you. Just reach out!

Good stuff, I'm liking what I'm reading. Have you changed the fluid in the transmission at some point?

I'm in So Cal, and would love some help in getting this done. I'm comfortable with getting torn down, but an extra set of eyes would be great too.

had a complete trans service about 30,000 ago maybe less. I love this car

once I get my coolant bottle Upgrade done I will do the vanos fix. she runs and drives fine and she gets up and moves pretty quickly and decelerates just as quick. do to the suspension she almost handles like she is on rails.

My single vanos M52 is very low mileage for its age little over 87,000 miles on it. General consensus on the forums is that the vanos seals fail very early. Until I have problems with the vanos itself, I will not be servicing it. I have not driven any single vanos M52's with the seals changed, so I would like to see for myself if there is actually a difference in timing performance.

If your expansion tank is not leaking I would leave it alone, I decided to do preventative maintenance regarding that part. Swapped my original expansion tank with a dealer bought one, the part failed in 2 months. I could just be unlucky in that regard, but everyone states buy the tank from dealer. Well its garbage, and there are some threads where a person has gone through multiple dealer bought expansion tanks that failed. So if the original one is intact I would leave it alone.
