Bro...this is very very helpful video. You have shown in details on how to do the timing adjustment using the locking tools. Your step by step procedures were easy to understand for DIY mechanic like myself. Thanks a lot.
Hey BimmerZen .. I´m a professional mecanic and engine tuner .. I want to Ack. you for a VERY fine good and helpfull video, that all people can understand .. Very good job !! :-)
I cant time my engine, my camshafts are 90 degrees apart, when the engine is top dead centre the flywheel bolt doesnt go in, and the intake camshaft is 180 degree upside down
Thank you for your clear instruction video man. I really would love to do this myself but I'm too scared to screw something up. But I'm still considering changing the stem seals. The high usage of oil keeps frustrating me
Even with service manuals and YT videos it can get confusing and complicated. If you do this yourself, make sure you are comfortable with procedure and have the necessary tools. Take extra care with reasembly and timing as some people had issues with broken springs, sliped rocker arms, incorrect camshaft orientation and valvetronic system coming apart... It's sort of an open heart surgery really :)
@@BimmerZen Hey BimmerZen, thank you so much for your reply! I really appreciate RUclipsrs like you! Pure quality content and everything well explained. And yea, I replaced almost all main oil gaskets and everything went well. But this is just another level. Thanks, still considering. I will post a comment here on your video if I did the job and succeeded! Again, thank you very much. Cheers
I am happy with your video doing timing n46 but I have a problem my engine runs at first start but lacks power and shows something like gears and valvetronic , what can be a fault please also explain clearly how to to install and set valvetronic and balancing shafts. Thank you Evans
Precisely what I was looking for :-). Super video. Thanks a lot. I was thinking of doing the job on mine. Big thumb up for the effort and clear explanation. Cheers
The former owner of my car has change the valve stem seals and I suspect he's done it without the locking kit,What I've seen in my engine in that cutout from the exhaust cam was facing towards the admission gallery and not the exhaust and those two vanos holes where completley missaligned,I'm working on it now and I hope I'm going to figure it out...
Hello! I can’t find Top dead center. I removed the little panel protecting the flywheel. I can see the hole when rotating the crank. I can’t get the pin into the hole. Please help.. i only have a few days left to do this job..
It's there, keep trying. Try to apply a little bit of pressure on the pin while carefuly rotating the crank near the approx TDC (determine that with a stick through the spark plug hole)
I did everything like you, but I have vibration on idle and knocking in high rev… also errors 2A88 and 2E97. I think it’s from bad timing tool, what do you think? Because before chain replacement I put in TDC and then place every timing tool except Vanos bracket, it couldn’t get in for maybe 1-2mm and I thought it’s bad timing from previous, but it wasn’t..
If it is correct, you can get the timing without a tool, by locking the flywheel with a piece of iron and locking the valve shaft with two locking pliers, holding the rotor (the metal part on the cvt) at a 120 degree angle, and tightening the cvt head screw and torque. Please tell me if you know the exact amount of cracks between the fixed crankcase and the movable crankshaft to the connecting rod and the cylinder head to the cylinder.
Hey man, here to thank you. Your videos have provided so many easy to understand and clear solutions to my problems. Now my car isn't starting and after measuring the compression I will move on to this.... Now just to find someone with the ridiculously expensive timing tool or then it is off to the scrappers with this piece of shit joke of an engine.
Please forgive my question which may sound dumb but I've watched this and the other videos about changing the valve stems seals and can't actually see how this is aligning the camshafts into their correct positions. On older cars you had notches on the pulleys to show where to align them etc but I can't actually see these camshafts moving into their correct positions except when they've been placed onto the head. If I've missed something please forgive, I need to do work on my cams so want to make sure I don't make any mistakes.
There are no "notches". During timing procedure the cams have to be locked with locking tools at the back, crankshaft must be locked with a lockig pin on the engine block and flywheel. Then the final timing is set with vanos impulse sending gears locking tool. In this "timed" position you then tighten the vanos bolts.
@@BimmerZen Ah ok, so the locking tool at the back will only fit at a certain point and that determines that the cams are in the correct position when the engine is at TDC?
When I put the pin in the flywheel I was still able to move the crankshaft (piston) 1 cm (or less) up and down. Is that normal? Mine is automatic. I think i didn't put the pin in the wrong big flywheel hole. The engine work looks normal after timing like that.
If you timed the engine with the pin in the wrong hole, then your timing is off. ECU can adapt the engine to work, but you will have lower power, lower efficiency and higher consumption. I highly recommend re-timing the engine correctly. When the pin is in the correct hole, you will not be able to rotate the crankshaft for more than a fraction of a degree, it's pretty tight;)
Check the manual here: www.newtis.info/tisv2/a/en/e46-316ti-com/repair-manuals/11-engine/11-31-camshaft/DpNzXt9 Look at the "Checking locking of intake adjuster in initial setting" and "Checking locking of exhaust camshaft adjuster in initial setting" section
hello, i've watched all your vids and several others on this topic. i've replaced the timing chain but now the engine just cranks but wont turn over so the car wont start. what would be a good place to start looking? there are no error codes, no blown fuses, fuel pump is working (spark plugs getting petrol and they spark). i'm really lost :(
Hi BimmerZen! What to do best when the locking tool on the intake camshaft has about 2-3 mm play after checking the timing right after a fresh chain replacement procedure? How to time it correctly when everything chain related is already put together and tightened? What problems will occur if I would leave it like that?
Hi, I have a question. Do the chain between the two vanos should be able to move up and down or should they be in tension against the chain guide ? Thx and great vid
Ideally it should be nicely tensioned between sprockets and rest firmly on the chain guide. Check the chain tensioner if you have the newest revision (pn 11318685091).
thanks for this video, my 316ti had an engine light come on last week to do with camshaft position sensor, replaced both but car isnt back to normal, did some research and apparently its the timing chain tensioner, my engine has 56k miles on it,do i need to do this whole procedure or just the tensioner? thanks
Try new chain tensioner first. If that does not help you will have to check the timing by removing the valve cover and using timing tools to check... Could be that your chain jumped due to broken plastic chain rail so take special look at that rail.
@@qassims6907 Not necessarily. Usually the plastic rail breaks first, and then eventually the chain jumps a tooth. You can usually also hear the chain rattling a little bit when the rail is broken...
Very strange. If the timing is off, the usually all 4 cylinders have lower compression. I guess it's best to perform a leakdown test and check where the compressed air is exiting...
@@alihasliel666 did you check with INPA? Or a scan tool that can read N42 ecu? Also check for vacuum leaks, vanos solenoid intake/exhaust connectors being mixed up, vanos adaptation should be aprox. 120 intake and 55 exhaust.
Not worth thinking about that. Just get the locking tool kit from ebay or something simmilar... It's not that expensive (i got it for 40 eur) and you can sell it if you dont need it anymore.
Quick question: I might need to do the head gasket on mine soon and in the process will probably do a new chain as well just to be on the safe side. Have you replaced your timing chain already and if so how/did you set the timing on the oil pump? I find only conflicting information on this and somehow the manual is also not clear (At least the one I could find online).
I haven't done a chain replacement yet. I have new one ready and I am just waiting to have some free time. There will be a video of course:) When replacing the chain you must remove the crankshaft bolt that also holds the oil pump sprocket. That sprocket also drives the two balancing shafts which means they can get out of position and mess up your balance... That's why the manual says you must remove the oil pan (PITA) and use a special locking tool on the balancing shafts to keep them in the right position when reinstalling the crank bolt.
@@BimmerZen do you have a source on that or anywhere I can check for more info. I'm about half way through a headgasket replacement myself and changing the chain at the same time. The thing is that I know that the enigine has been rotated when the crankbolt has been out, could this be a problem?
@@alexandersoderlund7279 it seems that if you rotate the crankshaft without crankbolt holding the oil pump sprocket, you could put balancing shafts out of alignment... I plan to release the crankbolt with locking pin inserted, carefully change the chain and reinstall without rotating crankshaft or rotating oil pump sprocket.

Hi Zen, is removing an oil sump a big job? I have bmw 320i 2006 with N46 engine. Will be doing timing chain and guides replacement so hopefully its a DIY job.
It's quite a lot of work... You will need a support bar to suspend the engine from top while you drop the front subframe. Then you will have to be very carefull when removing oil pan bolts as they can break off. Happened to me and i spent 2 hours just drilling out the old bolt and cutting in new threads. I recommend heating the bolts with heat gun. Also, remove and clean the oil pickup tube and inner screen. I found some debris and pieces of old gaskets in mine:) Replace oil dipstick/oilpan o-ring.
Changing the chain and rails is also a big job. Make sure you have all the tools and take your time. Read the service manual so you know the whole procedure.
I was wondering if you could give me your opinion on codes: P1061 and P101B that came on my bimmer. The car was loosing lots of oil and now it wont even start, just cranks. There is spark and all cylinders have 150 psi compression. Initially I was leaning towards faulty sensors or vvt motor but when I have opened the rocker cover I found that top timing chain guide is broken and some pieces are missing. The chain is still tight tho.
I have ordered timing tool kit and will check for timing. But I guess there is no way to go around it and will have unfortunately remove the sump and replace the chain and guides from the bottom.
I have a N46 engine, there is NO pin hole, i disassembled the engine, there is NO pin! not under the starter, not above the oil pan, nowhere. There is a gap on the lowest part of the flywheel but is just that a hole so you can lock the flywheel but not a circular hole for a pin to be inserted trough
@@BimmerZen found it, it was like really really deep inside. I had to kneel down almost all the way to see it but damn it's hidden in there. There was no plastic cover on it so yeah.
@@BimmerZen Okay so everything is back together, I changed the oil filter and I found small black plastic pieces Inside the oil filter and inside the oil/water heat exchanger. What could it be ? Chain guide? Can we chat somewhere more please ?

You need to remove the VANOS bolts and redo the timing procedure. VANOS bolts need to be replaced.
