We show in our own words how to setup and time the Vanos system on an E60 or E61 M5/M6 V10 engine. We show how to install and run the checks afterwards.

This is really great content and super helpful for us S85 guys. Tony is a wealth of knowledge.

Hello Brintech! Thank you SO MUCH for pointing out the "service" locking screw on the exhaust VANOS system on the S85. Many engines with loud noise and possible failure from improper disassembly. I paint my "service" screw in Yellow to avoid assembly issues. Cam bolts are stupid tight. Either I had a previously serviced engine, or on mine it was a middle mm bolt +/- 0.5mm from standard 6-pt socket. TTY bolts so they will be replaced. P-Chi

As some one else mentioned, you guys didn't explicitly show the short M8 bolt being REMOVED from the exhaust side VANOS assembly. Other than that this was a great video from some real pros, looking forward to more!

When do you take the locking bolt out of the exhaust hub? After the timing is done?

Thank you very much for your information. It would be great to know techincal information regarding the ideal piston ring gaps for this engine and also the ideal crank to conrod cap bearing clearances using plastigauge along with what manufacturer or type of bearings to use. For example acl, bmw or be bearings etc. Would be lovely to see or know how to overhaul a vanos unit also. Many thanks for your help its super helpful for me. Thanks

@BrintechCustoms - Is it possible to change the crankshaft and cams (inc. custom ecu) so that the firing order is the same as a Gallardo?

@jamesf2656 Жыл бұрын

One area of confusion: Tony quotes the 8mm-ish gap spec between VANOS unit and front timing cover. It looked like he just put the VANOS unit on and started to bolt it down without measurement. Obviously he did a visual check but what needed to be aligned in order for that gap to be visually in spec? In other words, what would be wrong for that gap to be wildly different from spec?

Great video! Any tips or areas of concern for reinstalling the timing chain to the gears?

Hi, I am currently in the process of rebuilding an s85 engine, could I get some help from you with a few questions as you are already after the rebuild and have a lot of experience. - Is a cylinder oval of 0.030 between the x,y axes acceptable? - Did you use any shells with more clearance in your rebuild? e.g. Be-berings or mehle motosports. - Is it a better solution to use forged connecting rods instead of om? Thank you in advance for your help.

Great video and great content, i love what you guys do 👍🏽, I am in the process now of rebuilding my s85 engine, the mistake that I did was I when I tore it down, i didnt put a bolt behind the exhaust cam gear to hold the two gears, how do I do it now? I searched everywhere and couldn’t find any solution

Hi! I just got my vanos actuator units rebuilt but they didn’t tighten the only screw holding the cap on the cylinders. Does anyone know how much torque is needed to securely lock that screw in?

So the problem I am having right now is the exhaust gear is sprung pulling in (instead of pushing out like in the video) and intake gear pushes out. So to get the gauge in place I have to pull the exhaust gear out. When I let go the exhaust gear pulls back in and the plate with the 3 bolts will not rotate back and forth. It feels like it is sprung against the 3 bolts. However in the video here Tony simply presses and pull the exhaust and intake in and out without any resistance. Idk if I'm doing something wrong or not. 2007 e60 7:00

Have you got the 6x allen head bolts backed off?

@@BrintechCustoms Yes vanos unit removed and remaining 3 bolts loosened. Intake gear pushes out then I can move the adjuster in and out rotating the bolts between the slots. The exhaust gear however is pulled in by the spring and I cannot move the adjuster in and out to rotate the 3 bolts in the slots. Instead the 3 bolts feel jammed against one end as they weren't maxed before I loosened them but sprung against one end after I loosened them and are stuck there now. We've ordered another gear (used as new is $1k and and 3 weeks from Germany) and in the pictures the used one we've ordered in pushed out instead of sucked in. So I will disassemble this one now to try to figure out what is wrong and/or different.

I conclude that Brintech must have one of the earliest vanos exhaust hub designs (circa 2005 or so) which comes with a CW wound inner coil spring. The hub’s resting position is extended. One has to apply a force to retract it, which in turn loads the spring. When the force is quickly removed, the hub “snaps” back to the extended position. This is essentially what's happening when the rotating lobes of the exhaust cam pass TDC of the hydraulic valve lifters and the cam “jumps.” The result is the “popping back” of exhaust hubs seen in the video. BMW later changed the design of the exhaust hub (circa 2007 or so) such that the inner coil spring is wound in a CCW fashion. This hub’s resting position is retracted. One has to apply force to extend the hub, which in turn loads the spring. (You will see in the service manual that BMW states NOT to remove the bridge from the timing kit after removing the hub “because the hub is under tension.”) While cranking the engine, the exhaust hub will not pull in then “pop” out as seen in the video. It retracts slightly, then remains in somewhat of a neutral position (since its natural state is the retracted position not the extended position).
