I think for most people the way to do this would be to check the valves are fully shut by using a cheap USB endoscope (you can get one for under £10) and rotate the engine by hand via the crank pulley. MUCH quicker and easier than trying to remove the cam cover which is a nightmare of a job on these engines, especially while it is still in the car. All modern diesel engines are a pain to maintain properly which is why I tend to avoid them.
Hello, great video - thank you. I'm doing a job that required taking off the intake manifold covers but the engine is in the vehicle and difficult to ensure the valves are closed. How bad is it if carbon debris gets past the valves and into the cylinder? And once this has happened what's the best thing to do about it?...Can you spray something in there to help burn it off?
Petrol engines can be almost as bad if the PCV valve is low slung on the block. Those can slurp engine oil into the air intake manifold. When mixed with the incoming EGR gases you get a nasty sludge at the ports. On my Toyota some of this sludge mix falls back and clogs the EGR ports. Oil catch can will relieve some of this issue. Great tutorial.
I saw a US video of them jamming a load of plastic zip ties into the drill bit, instead of the brushes. They don't get clogged up and are safe to use. But apart from that... They did it in the exact same way! Thanks for the video.
Wish I found this before I paid BMW $950 to do it for me!! They required I pay for it prior to them completing an EGR cooler recall on my 2014 328d Wagon. Thanks for a great video George!
awesome video i have a speed 3 and wanted and alternative to walnut blasting ($600au minimum) and scraping and was thinking about this today the exact same method. Champion
Thanks, I’ve followed your instructions, they are really close to perfect. Only missing bit: how to disconnect all the little sensor plugs without breaking the little clips...
Simply, clear and understandable illustrations. Thanks dude literally just ordered those brushes as l was watching the video.l had removed and cleaned the egr valve and intake manifold and was racking my brains trying to figure out the best way of cleaning the port and wala l see your video.

Now, in the spring of 2023, I think of solving this problem in my, in January bought, X3 30d 2011 with 246,000 km (160,000? miles). So now I have to gather information and knowledge of how to perform all this.
George aren't you turning the engine the other way around? I mean it should be rotated clockwise from the timing chain side so from the pulley side it should be anti clock right?
Hi! I have the same problem as mike hh. Don't know if there is a way to be sure that the valves are completely closed apart from visual inspection from the intake ports. And then, how do we know that we have rotated the engine 180 degrees exactly? Is there any easy way without disassembling the rocker cover? marks in the pulley?
Hello George ! Thanks for sharing this helpful videos ! I clean my intake manifold on my 320d 2011 , and now I arrive in the point to clean the intake valves like you do , but I see you have a special tool to crank the engine pulley for closing the valves , and I don't have it , it is another method to Crank manually the engine ? Thanks!
Hello George! I have a 118d N47 and want to clean the intake manifold, intake ports and valves. The big problem for me is the procedure to clean the ports and valves, because each valve should to be close when is cleaned. Is possible or easy to check through the intake ports the status (open or close) of each valve? And another question, if I rotate the crankshaft pulley to clean the valves, finish the job and the valve of the cylinder 1 is not in the exact position to the ignitión, this could be a problem or the digital electronic adjust it automatically? I don´t know if is possible desynchronize the distributión sequence making this job. ISTA+ recommends start to clean the intake port of the cylinder1 and them rotate the crankshaft pulley 180º to clean the next (cylinder 3), etc. 2 rotations in total to back to the initial position of cylinder 1 but this position never will be exactly the same. Thanks for your work with the canal, is very useful to me.
Already cleaned the intake manifold side and also fixed the oil solenoid wicking issue. Restored oil pressure and was enjoying a long awaited drive and the oil cooler seals went. Definitely a love hate relationship with these cars. I enjoy the learning curve and the mech work. Since the front ends off I'm bullet proofing common issues replacing seals/orings etc. And away to clean the carbon build up on turbo/exhaust side. Unfortunately I've found bust valve seals but cannot afford to fix and not confident enough to tackle them. In the meantime, while saving money, going to run the risk with thicker oil 5w40, forte conditioner treatment and a small amount of lucas engine restore. Hopefully it's not piston rings and will see it through until I can afford the fix. Let the games begin.
Hi George, can you turn the crankshaft manually with a breaker bar when the engine is in the car? I plan to DIY clean my intake and not sure if I should just skip the valve cleaning because I can't guarantee which valves are open/close without also removing the rocker cover etc. or using a camera which I cannot be bothered buying.
@rafh2753 Like George said, Yes you can be bothered. If you want the job done that is. Also, in America, our mobiles have cameras built in. No need to purchase. 👍
Man how can I find that extension for the brushes seperately? I have my brushes but I need an extension. What is it called? And second question is do I have to remove that top and see camshafts to make sure the valves are closed or can I see it by observing through holes?
There is a nut on the crankshaft on the bottom of the engine. Just find the correct size socket and turn it to crank your engine manually. *Make sure only to crank it in the direction it's meant to go**
Cool, I enjoyed the vid and also your other 1 cleaning the manifolds which I'm guessing are connected along this system. Now I'm not a mechanic, just in a situation where I'm having to learn how to do as much as possible as very limited supply of good and trustworthy, and affordable mechanics in my area I moved into a couple of yrs ago. So back to your vids and my Qs, ok, cool vids, and straight 4ward enough, makes me tempted to have a go myself, just saw a guy a few days ago and he recons this be the main problem with my van, but he not in a position to do it and if he was, he gonna charge me a fortune, and whenever he's got th time. But on this carbon clean. Suppose ya just do an engine flush, ok it's probably not gonna be the same as this quality carbon clean, but it's working on th same part of the engine and removing a lot of this crud? Or not?
Ok thanks 4 tha. Twas jus tha a "good mechanic" was telling me about th need 2 clean my intake valves and I'd wondered. Thing is tho, he also reccomended an engine flush which is something he regularly does with his clients cars, however I since learned that more often than not, an engine flush can do more harm than good to an engine, especially an older engine, so wondering what your thoughts might be on this?
Just done this on my Nissan QD32 which has 120,000km and man was it nasty, probably 25%+ blockage. EGR delete now done as well as venting the PCV/catch can to atmosphere instead of back into the intake hose right in front of the turbo. I did alot of manual scraping first with a variety of plastic and timber tools.
@@Boz1211111 the PCV routes oily gas back through the intake system, so a catch can will prevent that. However, I read online that adding a catch can, can fuck with back pressure and stuff and can cause rough running.
@@ZintomV1 yes, it ruts oily gas back in, but oil itself will just make it oily, as it doesnt get soot to cake up after egr delete, so venting pcv in atmosphere is pointless. And yes, if you do run egr some look into catch can but it adds resistance to the flow, and sometimes that causes issues One more issue of catch can is that some of them dont separate that much oil anyway so it can just help, but never solve the problem
So long as you make sure the valve is closed you shouldn't have an issue with carbon falling in, if you're talking about a small bit of carbon, it will get combusted and spat out of the exhaust most likely.
Just bout my first 328d couple weeks ago, and it threw couple codes P2004 (intake manifold stuck open ) and P2453/2454 DPF differential sensor circuit. There is also recall EGR cooler recall by BMW. What do I do ? Is it the soot builder up in the intake???
@@GeorgeAusters The only coke I worried about when I was young was the one they sold on the street. Now I'm worried about the coke in my intake. I tried Seafoaming it but still am not happy. I have full emissions on for reliability and because we have strict laws for anyone who removes um but I'm tempted to block the EGR
Can regular house cleaning vacuum be used to suck such a nasty carbon gunk mixed with solvents? I don't think so. House cleaning vacuum is not intended for liquids, plus the carburator cleaner can eat away plastic.
@@batchimed7392 I didn't hear him specify that it must be a 'house cleaning vacuum." I believe you should use whatever you are comfortable with. Perhaps someone can come over and hold your hand while you attempt to suck.
Hi George, due to fit an egr blank to a 2011 plate e91 320d, 84k on clock, fsh. I have been flooring it and hitting the limiter regularly to try and clean some carbon. Reckon after the egr blank is fitted if I continue to drive it harder the intake manifold and intake ports will "self clean" themselves to a respectable level? Or am I better to just remove Inlet and clean it manually. I've read that some N47n don't have as much crap In the ports? Worth pulling off to check?
