I've done the oil pan gasket before i started making YT videos, but maybe i will do it again when i do the chain replacement video.

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 KZfaqrs 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

Try Forte Seal treatment. It should fix the valve stem seal issue.

@@anton.basanisi I've already replaced my seals.

Peux tu m'aider à comprendre la vidéo je ne comprends pas l'anglais SVP

Register at newtis.info and you will have access to the online manual.

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.

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

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 know its a bit late but here it is: kzfaq.info3sTCKt5Oh00?si=tsWmWUGCZkd-isey

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 thank you, I think I must have missed the final timing part on the video

@@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?

@@wizzywilson Yes. Also, note that both cams have to be oriented so that the rounded side of mounting lobes at the back are pointing towards the top.

@@BimmerZen Thank you very much, you've been a great help

contact me on email listed in my channel's description.

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;)

@@BimmerZen that's also what I thought. It's not exactly how it should be, It runs but not fluent.

So the crankshaft is not turning when you start the engine?

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

Sorry, don't know exactly what you mean? Can you be more specific?

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.

@@BimmerZen so if the plastic chain rail is broken thats a clear indication that its jumped teeth?

@@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...

@@BimmerZen there’s definitely a noise coming from the chain, it’s more of a knock than a rattle though

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).

@@BimmerZen ok thanks a lot for all the information. I’m going to check for the reference and replace if needed. Thanks again

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...

@@BimmerZen thank you for the reply will look into that 🙂

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.

Manual here: www.newtis.info/tisv2/a/en/e46-316ti-com/repair-manuals/11-engine/11-31-camshaft/Fm9WV6P

Check out Sarka on the Ring channel for N42 teardown and rebuild: kzfaq.info/get/bejne/mpd1Zrdy2pPTfJs.html. There you can see how the balancing shafts work.

It depends on the country you are in. You could have N46B20 or N43B20: en.m.wikipedia.org/wiki/BMW_3_Series_(E90)

@@BimmerZen in my country it's n46b20... thank you

Not sure what you mean... you mean the front VANOS locking tool?

@@BimmerZen sorry I’m talking about the locking Pin that goes into the small hole in the flexplate

@@jovanthompson9669 There is a way where you can set the TDC on first piston using a measuring gauge: kzfaq.info/get/bejne/f7-earlkrbuvaX0.html

Yes, same part number.

@@BimmerZen thank you 🙏

Check for codes with INPA and check everything is connected correctly.

@@BimmerZen i have checked it with scanner no codes nothing and everything looks altogether and no engine lights on clock

@@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.

One bad scenario is that the balancing shafts got out of timing...

it can be balancing shafts.. im going to sell my car because of this

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.

@@BimmerZen okay thank-you so much

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.

Hi Zen, thanks for your quick reply.

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.

Sorry for the late reply! Did you check that the rocker arms are sited correctly on top of the valve? They like to slip off the when reinstalling the valvetronic unit or exhaust cam.

HI! Sorry for late reply! There should definitely be there but it's hard to find the first time;) You have to go by "feel" and use plenty of WD40 to wash of the dirt.

@@BimmerZen it was there took me at least 1 hour of trying to find it. took the high pressure air and made the diameter smaller.

@@FSandberg great!

What is the production month/year and model of your car?

There should definitely be a hole there: www.newtis.info/tisv2/obj/46sLKOC

@@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.

@@iOBBY227 Great! The world in back in order:)

@@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 ?

Yes, this is only the timing procedure, you can find much more info on replacing the chain in my other videos: kzfaq.info/get/bejne/hs9pmbqIs8yUl3U.html
