BMW E90 335i N54 Head Gasket Install: Finally Getting The Motor Back Together

[@dbnpoldermans4120]

Amazing to see the engine, so clean! That torque wrench is hot fire! Wow, like shift lights coming on! So cool. Thanks to Jake, you were a beast at putting the engine together! Now if something breaks we will blame you! Of course not. Also again thanks to all of the commenters here. Love reading your comments with tips, thoughts, questions and background information!

[@ZeroTo60Tube]

Hehe, yes Jake has offered a full warranty on the engine....:: I think hehe

[@NOne-yt1tj]

Good job! Been waiting for this for a while now. Nice to see the progress. I genuinely enjoyed this video; I've never seen an N54 head install

[@micraw714]

Can't wait to see this baby back in the road, you guys have come such a long way! I'm so tempted to order the same turbos 😁 💯

[@yezzusaguilar3097]

I love seeing the engine just out like that.

[@maxmoughal5183]

Whoop whoop! Major milestone there mate, cant wait to see it in the car!

[@ian.M440]

Very interesting seeing it go back together 👍

[@Fix_It_Again_Tony]

Glad you resolved the head gasket question. I see you didn't put new oil on any of the bolts internal to the engine. I have seen this as a step in quite a few other rebuilds, but not necessarily the N54. I can see how lubricated threads and bolt heads would impact torque, but maybe this isn't a problem with torque to yield (angle tightening) bolts? To your comment about BMW loving angle tightening, torque to yield bolts are annoying because they are typically considered single use, but they are great from an engineering standpoint because they assure even clamping force across the head or cam boxes without relaying on the technician to get the torque perfect or other variables that impact torque like lubrication or surface finish. The bolt is actually stretching and because they all have the same diameter the same clamping force is developed. This way each bolt is applying the same force and the head and cam boxes will remain flat and not warped.

[@ZeroTo60Tube]

I personally can't answer with any substance regarding lubricating the bolts. Jake has done it the way he was trained at BMW, but that doesnt always mean its the "best" way just because a manufacturer does it.

[@chrisrobles2012]

You bring up an interesting point about lubing the bolts. Bmw doesn’t want you to apply antiseize or oil to spark plugs while tightening them. If applying oil or lube to a bolt Ganges the torque spec , then does it cause it to be under or over torqued?

[@Fix_It_Again_Tony]

@@chrisrobles2012 Lubricating the threads would cause more clamping force (bolt tension) for the same torque because it is easier for the threads to slip past each other when lubricated. This would also cause more stress on the threads. It is very important when torqueing bolts to install then correctly, lubed or not lubed. Anti-seize should also be avoided on wheel studs because when lubed the same torque produces more clamping force and stress on the threads. See here: www.engineeringtoolbox.com/torque-lubrication-effects-d_1693.html I think Jake is doing it right. It just is interesting to me because you see the recommendation to lube the threads regularly, but I don't think it makes a difference for torque to yield bolts. I trust his method. I am sure he has rebuilt engines before with success. They took down NewTIS so I can't check what BMW recommends.

[@JerainJezza]

After seeing all the work in the last few videos with the broken engine, I'm more and more convinced I will never get upgrade hybrids and just stick with the fastest stock turbos OTS MHD V5 E40 map... :D 7 sec 100-200 is more than enough and I love the low rpm response for drifting.

[@ZeroTo60Tube]

Haha, i dont blame you. I think we need to see a dragy or vbox verified time, your car would be the fastest stock turbo N54 car in the world and its not even a custom tune.

The cam ledger has updated teflon seals, you should have replaced the old ductile iron sealing rings. The motor does look nice and it should run like it looks great work

Yessss! TeamN54! 😎

[@ZeroTo60Tube]

Soon soon!!! I dont want to jinx it by saying a timeframe i want to get it back together. But i'm hoping i get the motors swapped faster than i fitted the turbos!

@@ZeroTo60Tube take your time mate, better to do it properly than to rush 😉

[@cjlomax2156]

So now you can pull the old engine and see wazzup with that and possibly repair it for a spare. The cam box seal are a pain when they grove like that. Hopefully you can find some much cheaper ledges without a time crunch involved to fix that issue in the future. You'll be a pro by the time this is all said and done! :) Great content BTW!

[@ZeroTo60Tube]

Thanks man. The plan is to run this engine in stock form for a little while, the. Assuming the e92 engine isn’t too bad let damaged build that one up with some forged bits and other upgrades.

[@dodimolina]

I know this video is old but do you remember what was the final torque for the head bolts ?

[@ZeroTo60Tube]

They are done degrees. So its 30nm, then 90, 90 then 45 deg.

[@derekkchung]

3:31 WRONG!!!! of the 14 bolts inside, only the inside 10 are 30NM + 90 + 90 + 45. The outside 4 (smaller) ones are 30NM + 90 + 45. Google it! Don't strip your block!

[@nicenvall1842]

are the 4 smaller head bolts on the outside the same torque specs?

[@yiovanyrodriguez5656]

You should have still changed the metal ring on the cams to the new Teflon

[@ZeroTo60Tube]

Yeah, I probably should have. 2 reasons I didn’t. This motor is only temporary. And because of the wear already I was concerned that the new seal won’t seat in to the damaged ledge properly. Where the current setup the ledge and the metal seal have worn together.

[@crazygamer889]

You can get a whole new cam ledge kit for around $1100 usd on ECS tuning!!

[@ZeroTo60Tube]

Yeah, then plus freight and import duty makes it way too expensive.

[@Random-XP]

Good job. Did you buy new head bolts or you reused the old ones? Also did you say: 30n.m + 90° + 90° + 45° for the torque specs? And are the same torque specs applicable for reused bolts?

[@ZeroTo60Tube]

I used new Genuine on this motor, however this year i did another one using Nissan Diesel bolts. kzbin.info/www/bejne/mKW9fqKZeruXb9k

[@francoiscombrinck3884]

I have contacted a few stores hoping one would sell the insert however no luck, the best i could get was a bare bone block with a closed deck insert completed and machined. However that's in the USA and for the price you are better off just sending your block to het it done. That being said, if you can find a local machine shop to make an insert using either a 3d scanner and a cnc machine they could possibly make you your own insert. Then the shop that does the EJ engines could do the installation. It boggles the mind that stores are not willing to help. They want to sell you their services and that's it. It's not like closed decking is some sort of mystical dark art. It's literally just pressing a piece of billet aluminum into a block using the correct tools. Kinda like press fitting a bearing and machining everything to fit. After the story got told that the crank needs to be re clearanced i asked if the insert is going into the bottom or the top of the block 😂 and if its going into the top then why do you need to do any cutting at the bottom when using a stock crank. It's not like bmw will sell you a engine where the crank fouls on the bottom of the block. But anyway, just surprised by the replies. Will still keep trying, hopefully i get lucky.

[@ZeroTo60Tube]

Thank you so much for your efforts. I do kinda get why companies dont want to sell thier deck. If they sell it and someone doesnt install it properly they may get the blame when it fails. But still bloody annoying none the less.

[@FoolSendRC]

Were the head bolt threads oiled prior to being installed and torqued?

[@ZeroTo60Tube]

I personally can not remember.

[@a1a272]

What did you guys use to clean the block and head from gasket material ?

[@ZeroTo60Tube]

I had crc gasket stripper, a rag and a razor blade. That was all. I know some people use scourers but i didnt want to risk damaging the surface. If you keep the blade even and take car its safe. However a muppet will also damage it with a blade. It took probably an hour to clean off. Been running for about 18 months with no issues now.

[@odie0815]

since you did reuse the old cam boxes did you stay with the metal sealing rings or did you use the new teflon seal rings with the old boxes? my N53 has the same internal layout and at 195k km (approx 122k mls) i suspect mine are worn quite simmilar

[@ZeroTo60Tube]

Stuck with the metal. I was concerned the teflon wont seal in to the damaged boxes. I figured the metal is whats caused the groove, so it should likely match up and and seal.

[@glennarnold3970]

nice job i don't think that scoring will play up with the vanos on a different note have you looked at your dads car yet were the detent springs broken what about the fan problem

[@ZeroTo60Tube]

Hey Glenn, the e46 is registered. Fan was missing the resistor completely. So ended up just fitting a replacement second hand fan, plugged it in, fitted the fuse to the correct position and BAM it worked. Haven't looked in to the gearbox, however apparently its normal SMG shift speed. And to be fair it just feels like a SMG 3 in full soft mode, so i bet it is right. The ac is now cold (somehow) and one of the headlights did need some wires inside replaced. Some turps removed the black paint from the guard flashers. But yeah, it didn't take too much to get it registered. Currently on the hunt for a manual gearbox. I think that will be first on the list of mods.

[@xavir8002]

Great vid guys . Just wanted some clarification here : does the N54 come stock with forged crank and conrods and if so does the N55 B3M0 have the same?

[@ZeroTo60Tube]

The n54 does have forged rods, crank but cast or semi forged style pistons. That said the forged rods in the N54 are not as strong as aftermarket rods. They will handle nice peak power. But too much boost too low in the RPM range and they will bend. People say the N55 is not as strong as the N54, however i really have only seen failures due to lack of maintenance or people, well, really its following BMWs maintenance plans which are ludicrous. In my opinion the reason the N54s tend to make more power is the stock twins will flow more than the stock single on the N55. So same mods on the two motors, the N54 will net more power due to its turbos. That said the N55, will probably be more responsive.
