Thanks for the informative video! Applause from The States!

Your description was really accurate. Thank you for sharing all these informations. However, you missed just two points when comparing different N52 generations: 1- the downgraded versions of N52 (US specs) not only lacking the 03 stage manifold & the two DISA valves but they are not equipped too with the heat exchanger attached to the oil filter housing for engine oil cooling. This engine version is mainly dedicated to the 328i models designated N52N. 2- Not all new generation N52 engines equipped with plastic valve cover are lacking the 03 stage manifold. I have an N52K that was installed on a 2009 130i car is equipped with both: the 03 stage manifold with 02 DISA valves and the heat exchanger on oil filter housing. It is noticeable that these two are inter-related: 03 stage Manifold---->more Power---->more Heat----->additional cooling for engine oil is added.

So I got lucky I guess, I got a silver cover from (March) 2006 on a 530 e61, I am led to believe than not having direct injection they are both more sturdy and potentially accepting lpg conversions?

@petera8665

My 2007 E92 325i N52K have the oil heat exchanger installed. Could it be that the N51 is lack of the heat exchanger. I live in Denmark and all N52’s I have seen here have the heat exchanger installed.

Love your videos. I'm about to buy my 1st bmw. I've owned audi 3.2v6 and 4 2 v8 which I adored. I've owned mazda 3 mps also loved. Now I feel like a change and found 55 plate 130 m sport with 57k miles. My question to you is what should I be looking for at this mileage if anything at all. Pictures of the N52 look bloody clean but you're the expert.

Hi. I have a 2006 325I with a N52 silver cover and it has the disa valves. But its so slow. You mentioned MSV70... How can I have that updated?

What up, Dean! I got a N52B25 2.5 liters 218HP. My car has magnesium valve cover and intake manifold looks similar to yours with 2 disa valves. Is there any way to improve power in this engine without turbo, cutting the head or opening the velves? If I gain something like 30, 40 HP I'd be glad with my bimmer. Happy new year mate!

Your right about the N52 first Gen engine that it is one of the best engine. I want to ask you a question about the N51. Can I swap the N51 engine for a N52 engine and dress it back up with the parts from the N51 engine it is also a SULVE engine?

Hi mate, i have a 2006 630i sport convertible with the n52 268 bhp version 👌 mine has been tweaked and messed around with 😉however and its pushing alot more than 268, a true freight train 🚆 great video and info. Cheers

Howzit, just wanted to know if an E39 turbo manifold will be compatible with the N52. If not do you know any manifolds for my engine? Thank you!

So what’s the entire story with the bearing ledge wear? Only high revs during cold operation? Or is it lack of oil maintenance and cheap oil/filters?

U right bro , however the n52 with the black cover has improvements to the head so the ticking stops , and not forgetting camshaft was also improved cause of the bearing. My neighbour has a 2006 323i from new and bmw changed his engine under motor plan because off the same issues. So far his on 240000km only the ccv was a problem which he got someone to repair and re use his vavle cover. I believe the later n52 is more reliable , i heard a 2005 330i n52 and it had a very bad ticking noise.

bandity2k you then have the BEST N52 engine ever produced

How can a different valve cover effect the power, I'm looking at an 07 325i with N52, 2.5 litre and its 218bhp. Black engine cover, so supposedly n52n or n52k? Unless the official figures are over estimating....

Honestly surprised there is no decent aftermarket solution for the N51-52 plastic valve cover. There is an aluminum one, but I would not trust it. Plastic valve cover for N51 is now about $500+ so pretty wild.

What would the possible cause be on my 2011 BMW 328i making it fill the intake with oil? Also, causing it to blow heavy smoke out of the tailpipe?

Hey i have a 328I 2007 with a N52N , I bought a 3 stage intake to upgrade and i was wondering do i need to change my valve cover so ccv is relocated under the intake

From my understanding the SULEV models here in the US have the three stage manifold but that it's not activated. I know they were sold mostly in California and I think a few other states due to emissions. I have an 09 328i 6spd manual with the sport package and premium package and love it. Its fast but I want to make it faster and plan on doing the three stage manifold and down pipe in the future along with a blue chrome vinyl wrap. My dream BMW is a 440i MSport though with the B58 in it. Great video and I almost had bought a black with brushed aluminum trim 07 330i 6spd manual but someone bought it before I could. That was the bimmer that got away.😔

The 318i is a four cyl engine Mate

it would really help if you told us what engine was in what models

I’m thinking about putting the n54 in my 06 320i. How hard do you think it would be?

BMW Doctor well could I take the turbo manifolds off of a n54 and put them on mine? 260 bhp isn’t that much for such a heavy car. I just sold my 300 wheel hp Chevy cobalt ss.

@@racer2k5x43 Put it out of your mind, it's not a good idea at all. They may look similar but that's where the similarities between N52 and N54 end. N52 was designed to be lightweight, the N54 was designed to be strong. There's a video on youtube from BPC Motorsports that analyzes in depth the engine internals for both side by side. Bottom line, no matter what angle you look at it from, you'd be infinitely better off starting off with a 335i to begin with.

They made a few other minor changes including the throttle body, the n52n's came with the throttle body that has plastic molded over the butterfly valve probably to impede airflow and down tune it even more.

never removed the throttle body on them mate but thats very good to know clearly they was restricting it as much as possible and my guess is im sure more people will come who have taken this one apart and the original engine and let me know if there are any more restrictions the reason its limited here is because we never got that engine like you guys did there N52 only ran for 2 years here and they got rid of it completely

BMW Doctor great vid btw man! Also, The intake box on the us model N52’s are very restrictive with a flat triangular shaped filter as opposed to the euro spec ones that had a cone filter.

ChewbaccaFetus yes mate that too it was all to lower emissions as this N52 engine was way over powered and they thought it was this causing to much emissions and to much stress on the engine which it was all lies just to restrict vehicles even further

Does a 2011 come with a ccv breather or its just the pcv built on the valve cover

Everything after the LCI meaning something like March 2007

I got a 1st gen silver top. It's beautiful

You forgot the headers. They are a lot better in this early model. True 3-1 design with equal length piping. Later models have pressed sheet metal design and are more restrictive.
