Hi man. Whats your take for N53 comparing to N52? do they share similar issues?

[@CesarPerez-ck7ci]

@@stevet8607 I'm sorry for the extremely late reply, those valvetronic motors rarely go bad. Put a sensor in it. It'll fix your issue, obviously to be 100percent sure it would have to be tested. I have never seen the motor go bad (not saying it can't happen), I have done countless sensors for valvetronic faults.

[@evanupshur]

Awesome video! I have put nearly 100,000 miles on my n52 after buying it with 105,000, and I run it hard! ... I take care of it though; I warm it up, change the oil, etc. Absolute awesome engine. A true gem and the last of it’s kind from BMW. To add: It’s easy to mistake oil leaks around the valve cover gasket area. As Gareth mentioned, there are several areas on the valve cover gasket that can leak, so if you can rather than just replacing the valvtronic motor gasket or the valve cover gasket, etc., it could be the oil separator which happens to manufactured/integrated into the valve cover. It’s very difficult to differentiate where the leak is coming from, especially when there’s potential for the leak to be located in the middle of the valve cover where the spark plugs are located. Since all of these issues associated with the valve cover are common, I recommend replacing the whole assembly and saving yourself the hassle of trying pinpoint the exact leak point.

[@fcpeuro]

That's awesome to hear, Evan! Glad you like the video and thanks for the tips!!

[@drakyrra4565]

Hello there ! Great to know about , I need to know if the separator is integrated in all the N52's , or maybe only in N52K , N52B25AF ? I don't know if mine is in this case or just the separated one , I have the N52B25AF (BMW 325I e90 from 2006 , phase 1 not relifted version) just to know ^^

Thanks for the overview, Gareth! I've had to replace all of those items on my N52s except for the VANOS items (fingers crossed we are good there). But at 200k+ miles, my E60 has never run better. The E70 is hanging in well, too. One thing I learned the hard way from my water pump failure: flush the system (an extra gallon or two of distilled water is worth the $1) to ensure any bits from the old pump's find are out. I had one jam up my pump (which I bought elsewhere), so I made sure to do the flush before installing my FCP pump. I have an E93 with the N54, too; doing the clutch, brakes, oil and air filters this Saturday. Thanks again!

Excellent info! Have already addressed a number of these components on our 2010 X3. The oddest one was: we bought the car with a bad oil filter housing gasket. It had been leaking for a very long time. The whole front of the engine was saturated in oil. Replaced that and bought a new serpentine belt. Was kind of lazy and didn't get around to replacing it. During one long trip, the belt completely shredded itself. luckily it didn't take out the bushing mentioned. The moral of the story, replace an oil-saturated belt no matter how good of shape it looks. This one looked fine.

Remember oil cooler gasket and Valve stem seals (these go out from either drying up and shrinking or ripping and is usually a culprit from extended oil drains or age and wear like 20 years worth from factory year).

Thanks for all the help. My son has an 08 328i, 6 spd manual. 182k miles, previous owner completed most of the common failure parts, and kept it serviced properly. Still running strong, and is a super clean example inside and out. I love driving it when he lets me. I’m more of a motorcycle guy (and boring Toyota cars), but it is a blast handling the country roads. Had 1 bolt fall out of the power steering pump pulley and another one loose. Caused the serpentine belt to wobble and start to get shredded. Luckily he pays attention to noises and caught it before it broke completely. Got the bolts, belt and pulleys/tensioner from you all. Was an easy repair. Had the starter go also. Got the new (not reman) Bosch from you all also for a great price, along with the needed bolts and gaskets. Used your guys blog instructions to replace, very detailed and helpful. Wasn’t mechanically difficult, but was a lot to remove to get to it. Anyone considering a used BMW, would recommend an OBD2 tool with BMW software. Very helpful for research of issues, resetting codes, and used it to register oil changes and a new battery also.

There were tons of these sold. What do you mean not very popular? There are more out there than N54. Maybe they aren't popular in the enthusiast community.

[@MandusahRamirez]

I have 235k on my 08 528i sport package and still going strong!

[@dougrobinson8602]

So, bottom line is don't go 22,000 miles on your oil like the CBS will allow you to do. I drive mostly highway, but I won't go past 8,000 miles between changes. I've already done the oil filter housing gasket, which is a piece of cake. I'm steeling myself for the VC gasket and oil pan gasket, which I will eventually have to do. Thanks for doing this series on the last naturally aspirated BMW engine. It's a great motor, if you take care of it.

[@fcpeuro]

We agree Doug, take care of your N52 and it will reliably take care of you. Staying on top of basic routine maintenance is key, and doing some of the preventative problem areas we discussed in this video will help. The oil pan gasket certainly isn't a fun job, but its very doable.

[@stayvigilant7856]

I had a 2009 328i n52 with 150,000 when I sold it was a great car !!! Never gave me a problem just a small oil leak

[@dammichsmith]

Thanks for the info on prioritizing the various gasket leaks. I just got both on my '06 E90. Gonna get the oil filter housing done first now.

[@fcpeuro]

You're welcome, Damian. Let us know how the oil filter housing gasket replacement goes!

[@sander_storm]

How about the DISA valves? Heard some rumors about those failing too. Is this correct?

[@nicholasvonrhine6311]

I just want to say I'm a bmw tech and I love those cars.

[@gail6904]

what should the pressure RPMS on the 328i waterpump, 2008 sedan? thanks great videos..also in my old waterpump were orange pinkish pieces of plastic clogging the impeller fins and stopping them from turning.where did these pieces come from? thanks hope u cna answer~

[@BossIchigo574]

Got my own n52 328i right before the pandemic made the car market go nuts. Can confirm have had to do almost all the maintenance mentioned. Valve cover gasket was leaking, so was the eccentric motor and sensor seals. Oil filter housing seal also was failing. Ended up getting a new belt and pulleys at the same time (car was at 65k when I got it, closer to 73-74 rn) plus changed out the "mickey mouse" fitting on the oil filter housing with an aftermarket metal replacement. It now runs like a top and with no leaks to boot. But between all that and doing the plugs and coils (switched to the eldor's while I was at it) and tires it has cost me a pretty penny. But for a Montego Blue 328i with only 65k on it, I think all in I have paid 7k for the car and about 2k in maintenance. 9k all in for a sorted bmw ain't bad. Besides the front struts failing from living on a dirt road lmao

[@d3admaub938]

There’s an e92 328i I’m looking at that has had almost all the mentioned maintenance done, he’s asking $9k. 97000 miles, auto. I can negotiate with him I’m hoping to get it for around 7-7.5, but do you think that’s a decent deal?

[@L-Noble.YT_Hi.Res-Soundminds]

Thanks for the video. I have purchased many parts from you. Thanks for the quick deliveries and the profesionalism. I like learning more about the n52 so that I can keep my car going strong for a long time. God bless you all.👍

[@fcpeuro]

You are very welcome for the video! Thank you for the support , we are glad we're able to supply you the parts you need in the timeframe you need them! We hope to have additional N52 coming so stay tuned!

[@L-Noble.YT_Hi.Res-Soundminds]

@@fcpeuro You bet, thank you I also subscribed to the channel to keep the support for FCP going strong. My BMW says thanks ✌. Lol

IM about to take a 2011 328i off a friends driveway with overheating problems, any recommendations?

[@ciscovip1]

this great info. Keep it coming. i have 2007 328xi

[@fcpeuro]

We've got you covered Ciscovip1! Hope your 328xi is treating you well

[@ohyeahthatdude1760]

Thanks for this! Every e90 owner should watch this. I really appreciate your content and learned a bunch from you dude! From brakes and rotors to sensors and pretty much a lot of bmw related stuff. I currently have no heat in mine and I suspect a heater control valve or a clogged heater core, I was wondering if you knew the Inner diameter of a hose needed to back flush the heater core? That would help a lot. Again thanks a lot for all the priceless information for us DIYers!!

[@papillion6741]

Thanks for the info and I would like to find out, I am driving a 2007 E90 325i and it sounds like a diesel. My mechanic believes it is an oil pump not working properly. Can you please advise?

[@fcpeuro]

You're welcome, Papillion. If your N52 sounds like a diesel, worst case is that it could be a failing oil pump, however it could also be a faulty hydraulic valve lifer. If it is the valves making the noise, you can try some LIQUI MOLY Hydraulic Lifter Additives to see if it quiets the engine down. www.fcpeuro.com/products/hydraulic-lifter-additive-300ml-liqui-moly-lm20004

[@BlueJazzBoyNZ]

Excellent presentation. Talking from experience..!

[@vicroy5603]

Great video! I have x5 e70 n52 SUV. Looking forward to more about n52 engines. Thanks.

[@fcpeuro]

Thanks for watching, Vic!

[@maxheadroom4796]

I have lack of compression in cylinder 1 before I changed both vanos and new plugs and coils but still running like a tank told it might be stem seals are there any other possibilities ie.fuel injector looking at second hand engine if so car is bmw 523.i petrol e60 2006

[@AlecKristi]

replaced water pumps in several n52s and n51... never a logic board failure, always gummed up and hard to spin (probably due to wrong coolant). n51 was first replaced at 200k miles. I have heard of logic board failures from a mechanic friend of mine, but the half dozen I replaced were all in various states of seized )

[@troymoralisTM]

I’m having a crank no start issue, no codes for any sensors like the ones mentioned, and it seems like my DME and EWS is not talking to each other. My key fob works but my scanner won’t communicate with all of the modules. Like it won’t let me perform some active test because “it can’t communicate” but other things like door locks and stuff can be actuated. Do you believe I need a new DME? How would I know?

[@battlehrfred]

Hi excellent Video and Explanation in depth, professional video!! I have a question.... i drive a 2013 bmw x5 35i, 3,0 turbo with 138.000 kilometers,This is a N55 engine right?? does this engine have these same "Inhereted" problems or are the revisions have "fixed" all of these issues with older engines ?? Also @1115 you mentioned "cold start rpm fluctuating ? i just purchased this vehicle 5 months with no problems on startup and only just now recently i notice that when i start this engine cold in the mornings, it surges up and down between 750----1250 rpm for about 10 Seconds and almost shut down, After that it idles and warms up normally without any problems for the rest of the day, but it only happen when the temperature is 2 degrees or close to freezing, i live at east coast of Canada ty for input

[@Nosamarat]

This video might scare me into not buying a used 128i lol great video though! Very informative

[@dl94lopez]

Excellent video. Many thanks

[@fcpeuro]

Many your welcomes Diego!

[@TheSoulshakepower]

Thank you for all these precious infos. Video and audio quality is just amazing!

[@justinmijnbuis]

On some models changing the oil pan gasket is a nightmare as you have to drop the subframe. I have heard of a shortcut where you cut the gasket in a convenient place so you can snake it in place and cover the joint with RTV. Any thoughts on that (other than the expected "don't do it" 🙂)?

[@alfredosierra6873]

I just learned how to change my spark plugs and coils. Now just need to learn how to change an Eccentric Shaft Sensor. I really need a video from you guys. This on 2010 E60 528I xdrive N52 engine if I am not mistaken. Thanks

[@fcpeuro]

We can certainly add that to the list of DIYs we are working on!

[@spongebob7296]

What is the part number and name of the angled connector with the heater in it? The angled part with the heater in it : is that for the crankcase ventilation system? Also I have a 2009 Canadian 323i. I’m pretty sure it’s the 2nd gen N52 for LCI models

[@Dallas4131]

Awesome video, very knowledgeable guy!

[@muhammadsuleiman6860]

Hello I have 2013 x1sdrive28i it is frequently smoke I get a smoke for 5 to 10 seconds when start the car not always only ones every 2 to 3 days. Thank you

[@krackNsmackk]

So glad i bought an 04 325i manual instead of a 2007 328i like my roommate did lol. His is still sitting in the garage broken down

[@cliftonsargent1572]

Oil leaks are a right of passage???? I’m about to pull the trigger on a 2006 325i but I’m not trying to buy something that is gonna leak. I’ve had Benz’s for years and don’t have issues. Is this a common thing for BMW? I HAVE to up grade the oil gasket and I’ll be fine?

[@saganworshipper6062]

These are certainly all the things I need to watch out for. I bought my 2008 328xi 6MT about a year ago with 83k miles on it. All I know is it was a 1 owner car with no accidents but I have no idea if anything has been replaced on the car other than the previous owner had all of the recalls done. So far I have been lucky that all I've had to do is put gas in it. I had my mechanic look the car over when I first got it and the only thing he saw was a tiny oil leak from the oil pan gasket but there is never a drop on the ground so hopefully that doesn't get too bad too soon because he said it is a several hour job because of the x-drive. So I guess my only question is, do I just wait for parts to fail or would you be proactive at this point and start to change things? I now have 86K on it. (I live right down the street from my work so I don't put a lot of miles on it) For example, I have no idea if the plugs have ever been changed or what type of oil it's run on for it's life. Would it be a mistake to put LiquiMoly in it or Mobile 1 if it's only had conventional oil in the past? This is my first BMW and the car still looks pristine and I would like to keep it running as smooth as it currently does. Also, I live in Wallingford, CT and you guys are great!

[@fcpeuro]

Hey Sagan glad 328xi ownership has treated you well thus far! We always suggest staying on top of your cars maintenance and preventing possible issues from arising that can prove to create bigger issues. That being said its not necessary to throw every part in the book at the car. Sitting right around the 80k mark is really where we most commonly see things start to go. For now swapping the plugs, potentially throw in in a engine flush and some fresh LiquiMoly or another high quality oil simply cannot hurt (our most common www.fcpeuro.com/products/bmw-oil-change-kit-5w40-e60-e90-e82-f30-11427566327kt-lm ). Glad to hear you are local, be sure to swing by the retail center in Milford if you havent already (well once the current situation clears up)! From there just stay in tune with what your car is doing, dont let things go, once you notice an issue move to the remedy (your cooling system especially at that mileage).

[@saganworshipper6062]

Will you do a video on changing the valvetronic eccentric motor on a 2007 bmw 750li e65. And how to adjust the range or rather relearn the valvetronic unit using a Bavarian tech scann tool???
