Installing The BMW N52 Cylinder Head - New Head Gasket & Torque Sequence [BMW N52 Rebuild Part 16]

[@patrickcharest2050]

Damn!! So much details! Thank you for your awesome work! I hope your car won't burn oil ever again! You make me wanna do the same and follow all of your steps and don't repeat your errors when you show them! Again, awesome work mate!

[@buildanddrive]

Thanks so much for the kind comment. I hope these videos can help others because there isnt much info on the n52s on KZbin. Feel free to share with the n52 community! 🙏🏼

[@patrickcharest2050]

@@buildanddrive of course!! And i can't wait to see how you'll time the engine because as you said in that video, there are no very detailed video about timing on the n52

If anyone is doing this and you forget where the smallest goes its back left exhaust side.

[@buildanddrive]

Yep 👍🏽

Great video an amazing detail! I have not seen a lot of full n52 rebuild videos like these keep it up! Subscribers an views will come I’m sure !

[@buildanddrive]

Thanks Chad. Rebuilding the engine was tough as I had to pull information for all over the web. I hope these videos can help others, feel free to share them with your n52 community! 🙏🏼

[@SKWDMDYT]

I have been enjoying all your videos, but never will be doing a rebuild. Living vicariously through you. Still enjoyable. So my question, at minute 15:30 . Three of the four bolts in my N52, are broken. I can't see the fourth small guy so that might be as well. I replaced the external one because that is accessible, but the two under the valve cover might be too difficult for me. So what exactly do these bolts do, and will something terrible happen if I don't fix it. The car is my daily driver and can't put the valve cover back on until I find a solution.

[@buildanddrive]

Thanks for the kind comment! I assume those bolts hold the cylinder head together to keep the oil passages on the front of the engine (vanos, timing tensioner etc) held together tighter. Is your engine leaking oil at the front of the block anywhere? If not then maybe these bolts are just extra precaution designed by the engineers

[@iamurnamann8662]

Below the solenoids where the head meets the block seeps a little oil if those bolts you fastened at the end break or aren’t torqued correctly. You said you weren’t worried about the torque settings on those four bolts, but if they loosen over time, you’ll get the slight oil seepage. There are a couple of KZbin videos stating the bolt under the manifold is the culprit because the head snaps off, but I’ve seen that bolt in tact and it turned out to be the four internal bolts that weren’t correctly torqued.

[@buildanddrive]

Very possible there could be oil seepage over time. The bolt in the middle under the timing chain was broken when I took it out the first time. But I don't think it was leaking that much. More from the disa solenoids than the block itself

Waaauw great job !!! Ik have a N52 630i same engine (...White Smoke) can i do this with the engine in the car and do i need to remove the automatic gearbox ?

[@buildanddrive]

You can replace the head gasket with it in the car 👍🏼

[@Tinus001]

Thanks so much for you’re video’s helped me out to order the right tools. 1 thing i found out jn this video is that you torque down once. In the manual say’s torque down all bolts, the first bolt i could do another 45 degrees after all bolts. I walked all bolts three times to klik them instant.

[@buildanddrive]

I will have to watch it again to double check ✅ but I remember torquing them properly

[@LASVEGASAUTOREVIEW]

I'm having issues with my e90 right now ! Just waiting for the timing video to drop to make sure I can time mine correctly and to see if theres any issue other than that because it goes into limp mode after I start it ! But wont if I keep it above 2k rpm it's weird but then at idle it dies!

[@buildanddrive]

What codes is your car throwing?

[@dusanveselinovic7514]

I started to rebuild engine from cylinder head. When i remove valves intake and exhaus, i cant find to buy exhaus because they are 5mm and all n52 have about 6mm valves that is i think standard to this engine. I started to replacing valves to 6mm because that valves i can buy in my country. Can you tell me in your engine is it diffrent valves spring thickness for intake and exhaus or they are similar?

[@buildanddrive]

My valves were 5mm BMW 11 34 7 539 920. You can buy exhaust valves from your BMW dealer. Give them the part number. Or you can ship from Germany. I ordered from Leebmann online

[@getitdone6694]

Have a question the area where the head gasket goes on the block has both black(outer edge) and silver(towards center) shaped channels that includes the cylinders. On mine the black is not flush with the silver, I can feel it when running my finger over it. I noticed you did not actually remove it so I assume it is part of the original way the block is molded. My black area has some portions of it a bit worn off, you can see silver underneath will the head gasket cover all of it without having to resurface the face of the block?

[@buildanddrive]

Can you send me a photo of what you mean on Instagram? What time stamp in the video are you referring too? All I did was clean the block as best I could with some scotchbrite pads and a bit of sandpaper. You don't want to warp the block. The head gasket itself is about 3mm thick so I can fill in some gaps as long as it's clean. Send me a photo of what you are looking at. I still have my old head gasket I can look at.

What is the thing called you wrapped the blue tie around?

[@buildanddrive]

I have no idea, but its just a spot to attach the wiring harness too.

[@aphrodisiacbeyond9490]

Hi , do you changed your plastic guide or no ? If not , why

[@buildanddrive]

No, didn't change them because of budget.

[@DanielAlvarez-zi1yf]

Hola tengo n52b25 y me consume aceite mucho aceite, cada 300km me pone +1 litro, quiero repararlo, los anillos de los pistones cuando lo has cambiado has tenido que modificar cilindros ? O has metido anillo que manda el fabricante

[@aombarbor]

Is n52b25 cylinder head interchangeable with n52b30?

[@buildanddrive]

This is a good question, I assume they are the same. Hopefully someone else can chime in here to tellm I've never worked on a an n52b30 head.

[@jamiestanley8774]

Hi can anybody explain why all this + 90° + another 45° When your using a torque wrench . 2 different people will have slightly different ideas on 90° OR 180° ? yet bmw are so strict on tolerances. Thanks

[@buildanddrive]

It's 90' two times so the bolt can stretch, from what I understand

Oder kannst du mich weiterleiten wo du die Daten bekommen hast? Vielen Dank im voraus!

1 - Alle Schrauben mit 30 Nm . festziehen 2 - Drehmomentschrauben (nur #1 bis #10) 90 Grad 3 - Alle Schrauben um 45 Grad anziehen 4 - Bete, dass es richtig ist 😅
