If you have not watched the previous video please do so that you are caught up and can perform what is shown in this video.
Link: • HOW TO: Remove VANOS +...
In this video, we continue to remove VANOS components while still maintaining your engine timing. Our timing chain guide was actually broken and needed to be replaced. We are replacing the Exhaust and intake hubs because they were prone to having the teeth/tabs breaking off- causing catastrophic engine problems. We are also going to remove the Camshaft gears, timing chain guide, camshaft hub bolts and freshen up the head for any other damage. To replace the timing chain guide, yo must access the timing chain tensioner on the passenger side of the block( as shown). You may find problems with this tensioner like us so be prepared! We recommend replacing all these components being removed because they are prone to failure, and DR. VANOS offers the best solution.
This video shows complete install of the new timing chain guide which we recommend replacing as it is plastic and at this point guaranteed broken or brittle due to time. In the following videos we will be replacing the cam gears, hubs, bolts, and performing maintenance on the chain tensioner as well as the oiling system in the head. The VANOS is prone to leaking. So now is the time.

Dr VANOS timing chain guide
The VANOS has been a known weak-point of the E46 m3, so much so that its just as legendary as the car haha. Here at Fatboy's Garage we mean to correct that problem. In this series, we are showing you how to bulletproof your VANOS system on your BMW e46 m3 S54. Instead of rebuilding the OEM VANOS, we have chosen to completely replace it as well as other parts with upgraded components available from DrVanos.com These are the best on the market, so we highly recommend them above all others. They install perfectly and perform well, offering superior performance and durability.
An important thing to keep in mind when replacing the VANOS is engine timing, if dissassembly or reassemly is not done perfect, your engine will simply not perform.

this is the second time I saw a video in youtube on the broken tensioner guide, seem it a common problem and beisan got an upgrade one for that, btw good job for the detail diy...keep it up brother!!
Great vid 👍 Thank you!
Great videos! On my project, one of the studs that holds the valve cover unfortunately fell into the opening and I heard it clank pretty low. Any advice on a tool that could help me find it or advice on where it went potentially? My magnet stick had no luck. Thanks!
keep them coming brother!!
will you guys ever make a rod bearing video?
biagio lucci yes we will after suspension upgrades,after we are through with VANOS section we’re going to be moving into suspension upgrades, frame reinforcement and maintenance.
Simple answer though: definitely!👍
@@FatboysGarage I am looking forward to all these videos!
You guys do a great job on the "how to" videos. I really want to tackle my VANOS, but get pretty nervous because of the TIMING portion, and all of the little tiny steps. One question - what is the added benefit in switching out the Gear sets ? I would be terrified to touch the chain :)
the main benefit is to freshen the whole system up. so that you know its all new and can be confident in it. sometimes, when we leave old parts in and then those fail and we hav eto go back in again. Plus, we wanted to show how to do all of it. Yes- lots of tiny steps, but done right its worth it!
Beisan has an upper chain guide that is much better than the stock guide. It is rated for over 300k....fyi
What size socket is needed for the timing chain tensioner?
I'm just after this point, ready to put everything back on and when you do this, I guess the timing is ok but the hubs are off as well as the plate they screw into. I'm having a time figuring out where the spot is to line them up properly... I had to slightly rotate my exhaust cam to put it back in time with my timing tool. Yours fit like a glove with seems a bit disturbing to me for my engine. Hopefully I did this right XD
not being with you watching whats happening on your engine, I cant be sure! BUt compare and take notes in the following videos and lets see!
So I got the dreaded P0014 code for an over advanced camshaft. The car drives amazing and my idle when warm is perfect. Horsepower is there and everything is so much smoother now. I'm thinking that tool is just not built to the right spec and the camshaft maybe be 1 or 2 degrees off. It isn't a stored fault code but it does come back. I'm reluctant to take it all apart because I don't have the time to do this again.
Andy Freeman did you leave The way it was? Or did you take it apart again and fix the timing? I’m curious because I’m about to do this on my car and I’m debating whether to do it myself or have repair shop to do it.
looking for one in video
How do you tell apart the exhaust gear from the intake gear?
If you are talking about the larger ones( cam sprockets) they are the same gears. Or do you mean the splined gears?
What the engine making a loud slapping noise? Almost like a rod knock but not as aggressive?
I parked my car last night no problems no noises , not today there’s a loud noise://
Is it really necessary to change the sprockets? I didn´t do that on mine when i did the Vanos job...
Its not necessary unless you have excessive wear. We just did because they are often involved with the rattle you hear even with a healthy VANOS system, and we wanted a complete refresh. So no, its not always necessary.
can i get a link for that 32mm wrench?
please
there is a 32mm wrench from bmw/ecs that is the first link in the description. However, the one we used is a modified wrench we cut in shop. Buy a cheap wrench, and CUT it down to length required to fit in the area, a chop saw will do the trick. If any other questions, just let us know!
Did you just torque it down as hard as you could by hand? I read somewhere it should be like 70nm but it seems nearly impossible to get a torque wrench down there.
How much do you think a repair like this would cost (parts and labor)?
That depends, Are you asking about an entire vanos job? often when you go to a dealership and it has anything to do with VANOs, they dont bother doing the little things, rather they just install a refurbished vanos system and slap you with a 5k bill.
Where did you get the 32mm wrench?
Here is a 32mm/35mm wrench that doubles for a fan clutch wrench. Not the exact one i used but nonetheless.

The exact one we used is a wrench we just cut to fit. Worth it for the next car.
