      Quick question: What happens when you reuse the camshaft bolts?

    • @BimmerZen
      @BimmerZen  3 วันที่ผ่านมา

      @ensonlwesya4879 Nothing, if you are lucky and don't drive the car hard:) Otherwise, Vanos units can slip, causing timing errors. Worst case scenario they break; causing serious damage. In a pinch you can reuse them, just to get the engine running (very light driving), but I would never drive the car in everyday scenarios, given what is at stake:)

    ATTENTION ⚠️ Please Read This:
    It's very important to extra tighten the Zip Ties. Really tighten them very very good or better use even 2 Zip Ties. Like Jeff said please take care of the "Spring Legs" rested in the V-Shapes (8 times). This is super risky if the Zip Ties aren't tighten enough. And be really gentle with tighten down the bolts when putting back the whole thing. Do it in many steps/turns. First 4NM, then 6NM, then 8NM and finally 10NM. Bimmerzen thank you so much for your detailed videos. Really appreciate.
    Story; unfortunately in my case the whole structure fell apart. I had to manually put in the inlet Camshaft and the long rockers and the super heavy springs. Nothing broke but hell of a project.

    @ 4:45 - re making sure first cylinder is in TDC, with the @ 4:53 cutouts in the exhaust camshaft being on the 'passenger' side, well, that's country dependent! :-( Allow me to suggest to viewers that the message here should be understood as - make sure the cutouts in the exhaust camshaft are facing the exhaust side of the engine. :-) Thanks for these videos BimmerZen.

      Hi there. If you could help me with my situation. I followed the instructions by setting the 1st cylinder in TDC and then locking the inlet camshaft in doing so I can't seem to position exhaust camshaft in the exhaust side of the engine therefore, I can't lock the exhaust camshaft. any help is much appreciated thank you.

    • @Valden23
      @Valden23 5 ปีที่แล้ว +1

      Adrian Barraca Hello again Adrian. I think I know what the problem might be. The crankshaft turns two revolutions for every one revolution of the camshafts. You might need to rotate the crankshaft one full turn to get the correct TDC in place to align the camshafts where they need to be. Report back and we’ll get this sorted. 🙂 Edit: Provided the timing is as it should normally be, the correct orientation of the inlet manifold for locking is when the domed or rounded surface of its rear end is facing upwards. The other surface at that end is flat, and should be facing down. When you have this lined up, with TDC cylinder 1 locked, you’ll find that the exhaust camshaft will also be ready for locking, though it might need to be rotated clockwise slightly with a 30mm (I think) open ended wrench, to allow the exhaust cam locking tool to settle into place. Give it a try. 👍

    Hi, Thank you so much for this. Very good and clear.
    I have a badly leaky number 2 cylinder spark plug sleeve which is captive under the valvetronic assembly. do you think it would be posssible to remove the valvetronic assembly or lift it far enough to replace the sleeve without removing the inlet cam? Can I zip tie the rockers to the eccentric shaft but leave the inlet cam in the car still timed?

    • @TheAnthroheart
      @TheAnthroheart 6 ปีที่แล้ว +1

      Just found the answer to my question above. For anyone like me wanting to replace the captive sparkplug sleeve on plug 2 or 3...You have to do the whole cam removal as in BimmerZen's video. See: www.newtis.info/tisv2/a/en/e87-120i-sha/repair-manuals/11-engine/11-31-camshaft/3z6r31q

    • @BimmerZen
      @BimmerZen  6 ปีที่แล้ว

      Tnx for answering your own question:)
      You are correct. In order to lift the VALVETRONIC bracket you have to secure the whole assembly and cam with zip ties otherwise idler arms will fall out of place due to spring tension. If that happens you have to reassemble the whole thing and check that it fits correctly (PITA). If an idler arm slips it WILL damage or possibly destroy your engine!
      I try to "just lift" the VALVETRONIC assembly without securing it with zip ties in this video: th-cam.com/video/D6dNF5Yr3qQ/w-d-xo.html
      That "click" sound is when the idler arm falls out of alignment!

    • @BimmerZen
      @BimmerZen  5 หลายเดือนก่อน

      Yes, in general it's best to rotate the engine CW - keep the oil pump pumping and chain tight. But during this repair you can rotate the engine CCW because you also have to hold the chain tight against the crank sprocket.

    Hey! Thanks for the help, I have the same problem and have ordered all the parts. Would you recommend replacing the timing chain whilst everything is out for preventative maintenance? Or is it too much of a hassle

    • @BimmerZen
      @BimmerZen  6 ปีที่แล้ว +2

      Chain can wear and stretch over time and the tensioner loses spring tension. If you hear short rattle on cold starts (engine 12h in rest) I would recommend changing the chain or at least the chain tensioner (with improved version). More problematic are the plastic chain rails and guides. They get brittle over many heat cycles and can break, causing the chain to skip, valves getting bent and so on... If you want to be 100% just buy the whole set (chain, tensioner, guide rails, VANOS and crankchaft bolts) and change everything. It's a lot of work, but much less if you do it now...
      I already bought a set and will be doing the chain replacement on my N42 car so stay tuned for a DIY guide on that:)

    • @BimmerZen
      @BimmerZen  6 ปีที่แล้ว

      Are you sure you need this job on such a low mileage / new-ish car? Otherwise I would recommend also replacing vacuum pump seals, valve cover gasket, VANOS solenoid O-rings. They all go bad after 10-15 years. I will have a video on the vacuum pump seals replacement soon:)

    • @rohantait205
      @rohantait205 6 ปีที่แล้ว

      I scanned the car with a code reader and I got the code P0430 which is a code for the catalytic converter which could be from the excess oil going through the exhaust? I also got the code P1129 which is the downstream oxygen sensors which could also have been affected by excess oil going through the exhaust. When I got the car I drove it 1000KM in a straight shot, I started with the oil level being full and 3/4 through the drive I got a message saying I needed oil. I know BMW's use quite a bit of oil but not this much. You can smell the oil out of the exhaust and sometimes when I accelerate from a stop, a white cloud of smoke will come out the exhaust. Could be and hopefully is the CVV but the forums point to it not being that.

    • @BimmerZen
      @BimmerZen  6 ปีที่แล้ว

      Valvetronic cam carrier cracked?? I'm really interested in this failure... If you find the time, I would really appreciate it if you send me a photo to my email bimmerzenchannel@gmail.com:)
      If I had the same issue I would first try to replace the Valvetronic carrier from a same year engine model (just in case). Valvetronic disassembly and reassembly is very tricky, so you need some experience. All components must be put back in to same position, and eccentric shaft bearings ideally replaced.
      If you can get whole cylinder head for a good price, then replacing it could be a good alternative. Still a lot of work, but you can sell the good parts from your old head.

And every time it does,i can see the chain bounce up above the chain guide. Is it skipping a tooth? I just needed to get to TDC.

    • @BimmerZen
      @BimmerZen  4 ปีที่แล้ว

      If your chain guide rail is not broken, then the chain should not be able to jump. There is a small leaf spring at the bottom of the rail near the crankshaft sprocket that keeps the chain under tension (th-cam.com/video/Pi9fWWNf0gA/w-d-xo.html) even if the main tensioner is removed. I think you are "feeling" the cams compressing the valve springs. Does it feel like you are compressing a spring?
