I am putting a comment here so people cna learn from my mistake, make sure you already locked your timing for exhaust, intake and crank. Put the intake gear first, make sure you pull the chain all the way up and spin the intake gear anti clock wise as you insert this. This is to make sure that you don't leave any slack. Then do the same for exhaust by pull the chain to the top left and spin the exhaust gear as you put it back. Don't reinstall the colar screw until you put the chain tensioner back and put it to 65 nm torque. Put in the front lock tool and then put the OLD colar screws and torque them to 20nm. Remove all the timing tool locks, then do full rotation of the crank clockwise. Put all the timing lock back. They should all fall into place without much force. This means you are in perfect timing. It's time to put the new colar screw in and torque them to rhe specifications.

Great video, but where were you when i did my compact, i had to do so much research on my own and you have it all. Your videos will help many, keep up the good work man.

If you use zip ties (or metal clips from special toolkit) to lock everything in place and just remove the VALVETRONIC bracket, as one unit you don't need to reprogram anything. When you reinstall it back, everything is in it's original position. Usual symptoms of bad valve stem seals are blue smoke when pressing the gas paddle after idle and the engine is warm. For example, pulling from red light scenario.

Hi, firstly, I purchased your tool to compress the valve springs, best investment for doing this job so many thanks! Secondly, after doing the job the car now has a misfire. I think it could be a stuck lifter but I did have to wind the Vanos screw a few turns to get my camshaft locking tool out. Does my Vanos have to be reset if it was moved? It seems to have spark on all 4 cylinders. It starts from cold fine but as it warms up it’s a constant misfire. Any help or advice is appreciated. Also, no lights up on the dashboard, all good there.

Great videos! My sons 318i from 2006 are have the same sympthoms, so I am goin to do the sam job as you. I have a question: How are you locking the engine when you put pressure in the cylinder to avoid it turns? I have borrowed the right tool inc the locking pin to the crankshaft. But it is difficult to locate the right spot?

When placing the locking tools at the back, only one fits. Cyl #1 is TDC, exhaust lock tool fits but not inlet lock tool ?

I am doing mine tomorrow with two exBMW techies. The guide is broken and there are possibly bits in the sump. Two questions though. Would you suggest doing the sump work first and putting it back together and then replacing the timing chain or leave it open while doing the timing chain. What I saw was the reverse torx bolt behind the engine support mount will be inaccessible. I guess it could be taken out first. What would you suggest? Also, the exBMW guys made me buy the Timing Chain Service tool to rotate the crank in addition to the camshaft locking tools. It has three holes and two flat pieces for measuring. Was this really required? Wish me luck though.

I would suggest removing the oil sump first, then remove and clean out the oil pickup line. Make sure there are no pieces of plastic or old seals on the mesh. Also inspect the bottom part of the engine for any debris. Then put back the oil sump with just a couple of bolts to protect the inside of the engine from contaminants. Then do the timing chain and guides. When you are finished timing the chain, replace the old oil sump gasket and reinstall the sump. If anything accidentally falls in to the engine you will be able go retrieve it fairly easy. I never did a full chain replacement so I don't know this procedure or exact tools required. The manual (tinyurl.com/ybho4n8s) shows you need that timing chain service tool with three holes to release/tighten the central bolt while on full torque. Locking pin may only be used to release the remaining torque ( All the bolts are accessible via plugs in the block. Its a good idea to change the front radial seal, VANOS solenoid o-rings and plug seals while you're down there. Also don't forget to change the oil dipstick tube o-ring that seals to the sump. I plan to do a video on how to change the chain and guides and already have the new chain and guides ready, I just don't have the time to do it. Good luck and let me know how it went:)

I am so waiting for your vids. Don't you do any other car works? How about interior? Anyway, I did vanos work, guide seal work, valve tronic work. I could do all these works because of you. I really appreciate it.

@BimmerZen

5 жыл бұрын

Yikes:) I'm not 100% what happens if you do that. If you didn't install the VANOS/chain and the camshaft was rotating freely, then I think the valves should be fine - the resistance is from the valves that were under spring tension when the cam tried to rotate. Best thing to do is to check all cylinders for leaks if you have the leakdown tester tool...

@@nigellawes7902 When you unplug the eccentric position sensor, car goes in to VVT emergency mode and puts intake valves in full open position and throttle is regulated by ICV flap. Thats why engine runs "ok" with disconnected sensor. It is possible that eccentric shaft lobe, lifter, rocker arm or intermediate lever on cylinder 3 are worn so the valve doesnt have enough lift in idle when valvetronic is active. You can remove valve cover and inspect wear and valve lift.

Dude, soon I will be doing the same job + replacing timing chain.. Am I right understanding that doing valve stems job first is correct and then moving on to phase 2 and replacing timing chain with guides...? Also I have heard that if the guides weren’t broken, there is no need to remove the sump. Also the same guy was releasing the central bolt just with impact wrench and without a special blocking tool with three holes...So the crankshaft was blocked with a locking tool and then the central bolt was released and chain replaced... any thoughts? :)

@BimmerZen

I never changed the whole chain so i don't have direct experience with this job. I would say that you don't need to remove the sump if nothing is broken. I would suggest removing the cams before doing the chain, so you cant damage the valves if you rotate the crankshaft. Using impact and locking pin to release the main bolt might work just fine.

It took me about 10 hours without changing the chain. Professional technician with the right tools and a lot of experience can do it faster, probably in around 8 hours - if nothing goes wrong - which it often does on these older brittle plastic parts. I don't know how long it takes to do it with changing the chain. From what I've researched you have to remove the oil pan and make sure the balancing shafts are aligned properly (there is also a special tool for that). I would estimate it takes about 5 more hours. Oil pan can be a big PITA. You have to suspend the engine with engine support bar and drop the subframe (on E46 series at least). I've broken a bolt in the block while changing oil pan gasket it and it took me 1 hour just to get it out and cut new threads. Make sure they also change the valve cover gasket, vacuum pump seals, VANOS solenoid o-ring seals, oil level tube o-ring seal, oil pan gasket and clean out the oil pickup line filter mesh if that wasn't done before.

Thank you! If I understand you correctly you have slight smoke coming from the engine bay area and a smoke smell in the cabin cca. 30 sec after startup and then goes away? If that is the case, then you may have to replace the vacuum pump o-ring gaskets or the valve cover gasket. After 10-15 years they get hard and oil starts leaking on to the exhaust headers. That vaporizes the oil in to smoke wich gets in to the cabin.

Your symptoms are consistent with bad valve stem seals. There is a lot of vacuum in the intake manifold during idle which causes oil to be sucked pass the bad seals on valve stems in to combustion chamber. When you accelerate the oil burns away causing blue smoke and large oil consumption. I recommend you first change the seals and if that doesn't help go to the piston rings. It is still much easier to do valve stem seals first than changing the piston rings.
