- Project Cheapskate is starting to look like more of a bad deal with each repair. This time we have to dive into the motor to address an ongoing vanos issue. I thought after I found the broken bolts I was good to go. I wish that were true.... While I was in there I also replaced the eccentric shaft sensor and inspected my cam ledge seals on the intake cam.

So glad it started ok! 👌🏻 I was nervous with you 😮
I’m glad too. Just wish it was fixed. Ahhh this car.
hellow
hellow, my name is mussa and I am from Tanzania. I have encountered the challenge of engine N52 of bmw x3. when you rotate the engine, camshaft all work fine, but the vanos rotates for a while and then the camshaft rotates, then the vanos rotates, what should I do to help you
@@MusaSudy Hi, The vanos and the camshaft can move independent of each other without oil pressure. Is this happening when you back the engine up and then rotate clockwise?
We are going to figure this out!!!! I mean I’m sure you will 😅 I’m just here to cheer for you!
Thanks. I’m gonna get it I’m sure.
Hi mark from south africa check the vanos filters or install the vanos plats that was supplied with the vanos set it mite be thiker on the matting service
Thanks for the feedback. I’ll look into them.
I highly doubt that you torque the spark plugs to spec, considering that you use a regular ratchet.
It’s not shown, but I do always use a torque wrench on all my plugs.
Does anyone know if there's a difference in the intake and exhaust vanos Phaser?
I bought an x3 with exhaust Phaser codes. Pulled the valve cover and both phasers have the same part number which come back as intake phasers.
The intake and exhaust phaser/vanos units are different(intake-11367583207) (exhaust-11367583208). The impulse wheels are the same.
Great video. Doing this job soon.
Shouldn’t you be able to slide the pin into transmission once both QR codes are on top?
In a perfect world yes. But even with both QR codes up there is a few degrees of manipulation possible, especially with age on the timing chain. That being the case I get the cams close, just before tdc then from underneath I rotate the crank, slowly. There is another opening just before the tdc pin that you have to watch out for. Once the pin drops in I go back up top to verify the timing tool drops on. Sometimes, depending on your vanos unit wear you may have to advance one or both cams slightly to line up. But just a little bit.
Thanks for your reply. It’s a hell of a job and this video really helps.
When you turn the engine by hand, should the cams and all belts rotate straight away? I tried turning mine and only saw the vanos to turn but not the cams.
@@miketurin5233 That depends. The belts yes. The timing chain yes. The cams, maybe. Because they have the ability to advance/retard timing around 60 degrees they may be advanced when you pull the valve cover off. Meaning you'll start turning the crank and they may not move just yet. Especially if the vanos units are worn internally. What I would do is rotate the engine by hand 1-2 revolutions to bottom out the adjusters. Then everything should move together. I wound up doing this job 4 times on this car because the vanos units I installed from Ebay were junk and that took a lot of diag to figure out. A video about that will be coming out later.
This seems to be a straight forward job but the PIN locking drives me nuts. 😂
My pin locks much later when the QR codes passed the top position and both plates are tilted on the timing tool to the right. How far would you say could I turn the camshafts back so they align with the timing tool? I would say they are half an inch away when looking at the plates. Yours were only a little
I am also wondering if I really have to lock the flywheel if I already locked the camshafts?
Hello, and what's going on, I bought a whole set of chain and vanos and I will be replacing them.
Nice. My chain didn’t seem to be loose and the guides were in good shape. Perhaps later I’ll replace those too.
@@DrivingForwardBuilds Hello! Have you already solved this problem? After replacing the timing chain and Vanos gears, after starting the engine it ran smoothly and quietly, but as soon as I started it started to wave and it was impossible to drive it, I read the errors and error 2A98 appeared. I replaced the solenoid valves and error 2A87 appeared :( I don't know what to do anymore, do you have any ideas? I will add that before replacing the timing and gears of the Vanos, I had the error 2A82 in the Vanos intake. I cleaned the Vanos filters, they were terribly dirty. After cleaning, no errors disappeared they didn't appear and I drove for a week and everything was fine. Only after replacing the chain and Vanos wheels, such things happen :/ I don't know what to do with it anymore
@@adamus0909yes I have fixed it. It turned out the Vanos units I received were faulty. As they warmed up they got tighter and would bind. I ordered new OE units from FCP Euro and they fixed my issue. If you have quality units I would look into other areas first. Did you inspect the cam control oil rings? They are either steel early design or teflon the updated design. You want to make sure the caps aren’t heavily scored as well. The oil filter housing would be next(is the stem and seal there), and if your vanos filters were really bad even an oil flush can help. The vanos/oil system is sensitive to flow.
@@DrivingForwardBuilds Ok, thanks for the info. I thought that maybe the timing had changed, because before replacing the timing, Vanos gears and cleaning the Vanos filters, the car had no errors, only after replacing the timing and Vanos the errors appeared. Do you think the timing could have changed in some way? Everything was adjusted on the locks, etc. The oil filter housing was also replaced, and the vanos solenoid valves were also replaced with oem BMW ones.
@@adamus0909 Is it possible you have the Vanos solenoid connectors on backward? They are interchangeable and would cause some weird errors. I would hook a scanner up and log the Vanos values. You want to see the requested value and actual value to confirm they are working properly. Then go from there.
How many miles on this engine?
178k miles.
@@DrivingForwardBuilds Thanks. Good detailed videos!
Thanks. Appreciate the comment.
Mine has 75.000 miles and the same issue. This can occur at any time I guess.
@@miketurin5233 This is true. I've read reports of it happening at all sorts of miles. It does seem unique in this case that these were still original adjusters at 178k. I guess I'm lucky, or unlucky since I just bought this car. lol
