BMW says that you can address carbon build up by running the engine at 3k rpm for several minutes, especially if you do a low of low rpm driving. I make sure to take it out every few days and work it to 3-5k in sport mode for a bit. Since I began doing that, the engine is performing like a rocket. Also, I have begun. at 138k, a slow investment in the motor, shaft sensors, seals, belt, vanos, OCV, and soon, the DISA. Ill probably keep investing. The mechanic’s son told me, “I think this is a fantastic BMW, it drives so well.”. The 52 is a marvel of efficiency.

I drive a 06 BMW 325i with this engine, only smaller displacement. Had to replace the expensive water pump once and the oil consumption went down to zero after replacing all these gaskets. This engine is - even after 17 years and almost 120k miles - as smooth as on its first day. By the way: since I had the above mentioned issues I looked across youtube for videos explaining parts of this engine and this clip is by far the best !! 👍

06 525i : same history - very smooth.

This engine is actually pretty reliable and fault-proof for how complex it is - aside from direct fuel injection it got EVERY thing you can think of for optimizing that natural aspiration... It's main problem (just like every BMW) is usually it's oil consumption, but then it depends on how it was driven and maintained. What really amazed me is that i seen engines having their head rebuilt yet required no work on pistons/cylinders after 10-13 years... Although their design/materials do contribute to that oil consumption somewhat. Otherwise the only thing that kept annoying me was DISAs, but mainly because you have to crack them open to service them and they tend to fail without you knowing yet they affect performance greatly.

Yea. I've had an E46 M54B30 and currently have an E90 328i with the N52B30. I can take that M54 and tell you everything about it. This engine is a bit more complex. I am mixed on the port injection vs direct injection only due to the fact that I don't have to worry about carbon build up on the back of the valves. I had a 2016 Malibu Limited LTZ with the 2.5L ecoboost. Had put 152k miles on it and the valves had a bit of carbon on the back. My E46 and E90 have clean valves at 230k and 192k miles, respectively. Overall, the N52 has given me very little issue. I just got the part to change the OFH gasket, but the process actually looks easier than the M54 one.

Unfortunately, I had to learn how it works because I had to replace the eccentric camshaft and the valvetronic motor on my N55 engine... Fairly disappointed that BMW decided to put a plastic motor inside the engine.

I can tell you exactly why this failed, not sure why someone would ditch this engine because it was 100% repairable. Notice how at around 5:10 the intake VANOS gear basically came apart. That's not supposed to happen. On the N52 engine specifically, the VANOS gears are held together with a "safety" or "tamper proof" torx bolt setup, which are very prone to shearing off. This causes the engine to have a crank no start condition due to the camshaft no longer turning with the engine. It can be the cause of a lot of misdiagnosed "faulty" engines as well, due to the camshaft being stuck in one position resulting in no compression during crank. That's likely why this engine was removed from its home. Seen it a lot, and replaced quite a few VANOS gears in my time for this exact issue. Engine looks pretty healthy, all it needs are the VANOS gears and to be re-timed. Edit: you can see the bolt heads in the oil pan at 19:17

One of my favorite engines, had one in a e90 from 70k km to 150k km did 4 oil changes 1 radiator 1 coil pack and 6x spark plugs I was super pleased with the motor and oddly I never had an oil leak was still very tidy under. I have since upgraded to the newer B58 I-6 3L single T and boy do I get similar vibes in the robustness

Like you mentioned, these engines were sensitive to proper oil pressure- so make sure you don’t have run low on oil, or even overfill the oil level. A really nice engine, overall.

I got this engine in my F10, 5000 km since I bought it and I can say it has enough power for smooth daily driving, the sound is also very nice. I also have the oil leak from the valve gasket cover and now I know how to remove it :) Thanks, great video. Saved on my playlist for future garage repairs!

Nice video using the proper information! What I like about BMW's are the online support community and the easy availability of actual engineering and mechanical data. Thanks for a proper tear down!!!

I got this motor in my 2006 3 series. I got it six years now and its been pretty awesome. Enough power, smooth as butter and it handles great. Mainly because its my first rwd car, I've had 5 fwd cars before the 3 series. Just gotta be handy with a wrench. If not its best to get a Toyota.

Awesome video man, I was trying to learn very details of n52 since I am a fan of last naturally aspirated BMW 6 cylinder engine. Thanks again.

This video was very informative, well put together. Learned a lot of new things about my engine. Thank you !

Thanks for this N52 teardown! I'm an owner of a BMW 328i X-drive with N52 engine. Yes, I have done the valve cover replacement including the gasket. I've also replace the oil filter housing gasket. And replaced the coolant hose attachment (plastic) located at the oil filter housing. I replaced it with a aluminum one. I've also put in some AT-205 to stop oil leaks on the other gaskets. This seems to be working quite well. The engine itself is covered in grease and dirt. But it runs well and I enjoy driving the car. It is unbelievable how many rubber, plastic parts there are in a BMW. Lastly, BMWs need to be driven hard. So that the carbon build up goes away. Give the engine an Italian tune often and it will last longer.

I find it very difficult to get good fuel economy in my e90 328i 6mt because I just can't stay out of the throttle, I'm so tempted to floor it and row through the gears everytime the road is clear.

@@spicysnowman8886 yeh it nice to ring the engine out because of its linear power delivery.

thank u so much from spain!!!

Love the N52 I have in my E90. Lovely with a 6MT. Seriously looking for another in the form of a 128i Cabriolet with a 6MT. A few tasteful mods and it's a great summer car....

I had a few days with this kind of engine in a 125i convertible. Amazingly smooth, eager to rev and the sound was pretty good for a stock engine. Getting into an old school, NA 6-cylinder BMW when you're used to 4-pots is quite an eye-opener WRT smoothness and general "engine manners". It did feel a bit underpowered, despite its more than decent hp-rating, but that was probably just the car being overweight.

Awesome video

Love the video dude I’ve got 2007 bmw 335i it’s still ok other than the valve cover gasket coolant bottle elbow on the front of the engine it’s an n54b30 turbo motor 6speed manual

I also did not know the oil sensor also analyze the quality of the oil. Awesome.

Nice video!

Got this engine in my 328 and I've been very impressed with it. Never had a leak anywhere (knock on wood) and I've had it for well over two years and about 35,000 miles I put on it (182,000+ in total). I would actually recommend a 328 with an n52 as a first car if they want to learn how to work on something different and unique!

Best channel on KZread.

you're realllly funny . . . in a verryyyyyy sneaky way 😁👍👌 , nice video mate, you flow like a river without wasting a MOMENT of time on unnecessary chit chat or losing focus by dwelling on off topic chit-chats, you COVERED a TRUCKLOAD of information about this engine in possibly a 4th of the time it would take rookie engineers to explain the EXACT same thing, keep it up 😁👍👌 !!

19:02 You can spot in the oil pan two broken screw heads from the VANOS gear.

Great engine and great vide as always! I would love to see you do a dissection of an M50/52/54, the evolutions of which ran from the e30 to the e46 primarily. They don’t have all the fancy Valvetronic stuff but they’re stout and “classic BMW”

Wouldn’t call a magnesium engine great. Built in obsolescence Your better off with the M54, at least you have a fighting chance of repairing it

Awesome vid!

Thanx for your very clear and interesting dismantling and explanation of this engine. I enjoyed it very much. It is unimaginable that this combustion engine technology is both ingenious but so very flawed at the same time. Humanity has taken over 120 years to perfect this, but it goes this far and no further. It never gets better than this. Personally, I'm glad we're going to electric because it's many times more reliable than an internal combustion engine with only a tenth of the moving parts compared to an internal combustion engine.

Got my third n52 I also had 4 m52 and 5 m54 as well as 2 n55 and 1 n54 and 6 non r6 engines Great engines, enjoyed them

that's exactly why I wanted a car with small, normally aspirated inline 4 engine, in 2017. Luckily, Mazda had me covered :)

While this actually isn't the last NA I6 BMW has produced, they aren't far apart. The last NA I6 BMW made is actually the N53, which came in both the N53B25 and the N53B30 variants. It's basically a slightly altered N52 engine, with one of the big changes being direct injection instead of piezo injection. Since we've owned a N52 E61 and now a N53 E60, I can definitely confirm the oil leaky part about it ;) hehe. The video is super great though, and thanks for going through it in great detail! Cleared a lot of things up! Always good to learn new things about your car!

N53 wasn't available in all markets whereas the N52 was which is why it it often said to be the last NA inline 6 from BMW when actually it wasn't in some markets. On the whole though I think the N52 is better without the direct injection of the N53.

@brianlobo1512

@@joebloggs4191 Agreed. The N53 didn’t have the 3 stage intake of the N52, IIRC. The simpler valve cover and port injection are a plus of the N52.

happened before N52->N53 switch, later N52s (N & K variants) also lost the 3 stage/DISA intake and therefore some power, somehow with all this they managed to make the whole plastic valve cover with pcv integrated setup that was both less reliable AND cost more, smh @ BMW

Any idea on a secondary air injection failure bmw said my air ports are clogged which ones would that be near the head?

thank u for sharing❤️❤️❤️

I have an 04 530 with an m54 and 200k miles later its still going. Now I'm looking into getting a 128 and I've been hearing great things about the n52

Get one bro, I got a 130i with lots of miles and it still runs perfectly fine

This is a good engine, just keep up with the maintenance and check the plastic parts regularly.

Would love to see a review on N57. With special emphasize on road bearings failure. Lots of mystery around the cause. Oil Pump, Weak bearings, Bent shaft, etc...

I was hoping to use a oil siphoner but I'm thinking it's not possible. Do any of those holes in the oil filter housing lead to the oil pan? In regards to using a oil siphoning tube

please do a similar video on the 6SP gearbox. TY!

Great Video the N52 is the last BMW lightweight and technologically advanced I6 Naturally Aspirated Engine that makes 195kw/315nm that's a lot this engine is starting to get a lot of recognition lately or it's just KZread algorithm because when it came the N53/ N54 took its spot light and its proved its self as a reliable unit.

Nice short briefing.

Its the last NA inline 6 engine anywhere, but its not the last inline 6 gas engine. The turbo B58, which powers any M40i vehicles and the Mark V Supra, came soon afterwards. This was followed in 2017 by the Mercedes Benz M256 engine, then in 2022 by the Stellantis Hurricane 6. Then there's talk that Mazda will come out with a Skyactiv inline 6 for the next gen Mazda 6, an engine that Toyota is said to be in talks to use for itself. I don't know if the Mazda straight 6 is naturally aspirated or turbo or comes in both. Great video by the way.
