THANK YOU for not adding any music! Allows viewers to concentrate on what you are doing. Great stuff. I am learning more about BMW engineering by seeing these things. I'm surprised you didn't do more cleaning of the valves and intake chambers.
I wanted a more mechanical, raw videos, so I'm glad you liked it! I did some cleaning on the valves and the intake chambers, but I couldn't get to everything without a proper parts cleaner booth. It's been running pretty smooth so far, though!
@@1ROWDY35I think he mentioned it took $3k to rebuild. I am not sure but in $3k you would get an engine that’s at 300kms I think. Rebuild would be a brand new engine so yeah
Incredible video. I remember watching the individual parts and that was cool, but as someone that probably will never rebuild an engine, I watched this one all the way through and thoroughly enjoyed it.
Done well do far except the bedplate sealant, the proper way is to install and torque the bedplate and then install the front and rear seals, then use the syringe and push the sealant through the channels in the side of the block

Great Video compilation. I actually watched all the actual videos, and used the material to rebuild my '11 x5 N55 engine. It spun a bearing, number 2 cylinder. I replaced the engine, with a newer model, but kept the bad engine and rebuilt it. Now i have a spare engine. 😎
Nice job ! It's great to discover/learn more about our engine architecture. (here for me, injector seal replacement and installation. Never seen this before in any video) ) Why you didn't tackle some other weak points of the N55 during this rebuild ? Cost maybe ? I'm thinking about the water pump (more difficult to replace while the engine is installed in the car) And install a protective plate behind the harmonic pulley to prevent damages if the serpentine belt is escaping. Finally, what is your exhaust ? It's sounds so sweet to my hears. Love it.
I mainly did this to learn exactly how engines work and to challenge myself to see if could do it. The cost was definitely a factor as I ended up spending basically the same as it would cost to buy a used engine (although with 90k miles). The water pump was placed less than a year before I got this car, so figured there was no reason to spend $400. The protective plate; however, was something I wish I installed, but at the time I didn't know those existed :). The exhaust is COBB cat-back exhaust: ua-cam.com/video/Ue_d8Y6-EZE/v-deo.html Thanks for watching!!
it's kinda funny that you had no reaction to literally huge bits of engine parts just littered in chunks in the beginning, but having an audible surprise to a part beins heavier than expected. What are those broken bits anyway? turbo chunks?
the damage on the crankshaft and It bearings should happened due a low oil pressure, did you check the cams? it should be damaged too. The work that you did was great. But you had to change the oil pump, the piston rings at least and check the cams....
Thanks for the reply. Progress has slowed because my crankshaft would not turn well once torqued the bedplate. Machine shop has crankshaft and they say it is fine, I have identified 004 in of runout on the crank. Your crank was bent also right? How did you remedy this?
Great wotk... Just one question you prepared the whole engine but why you did not check and have a look on the other pistons and thier rings... Just replaced the the damaged one
No need when installing aftermarket bearings. I tested using plastigage to make sure the bearings I got worked for my set up and it was bang in the middle, so basically perfect. Thanks for watching!
Not sure why you didn't remove the pistons and clean them out of the cylinders so didn't deposit all of the crud into the compression ring grooves. Even if you weren't going to replace the rings, which would have been a good idea, it wouldn't have been much more work.
How many miles did your old one have before this happened? Also, how much more expansive would it be to do some sort of block guard? While everything is open? (For future high Hp applications)
Great work Can you explain at beginning of the video. When you started to fit bearing so you had two sets of bearing Sounds like you check clearance than you took off bearing than installed different bearing again. Not sure if I made sense 👍🏻
For both main and rod bearings I used my new bearings with the old bolts to measure the gap and make sure the clearance was within spec using plastigage. I have a video on plastigage if you want to learn more. Once everything checked out, I put some assembly lube and using new bolts torqued everything to spec. Using new bolts is vital as these are stretch to yield bolts and if you use old bolts, you won't get correct torque figures. Hope that helps! Thanks for watching.
Not that many special tools. You'll need a timing tool, injector tool and few other smaller items. I have a link in the description with stuff I bought for this project.
Could you show or add / send a link to where you found all the torque specs please! I’m in the process of putting my engine / subframe back together and I can’t finde torque specs anywhere…. Thank you!
Most of the bolts on this engine are torque-to-yield, which means they stretch as torque is applied. To make sure the 'stretch' is exactly as it should be, BMW says to use a torque wrench and tighten it to, let's say, 90 lb ft of torque and THEN add additional 90 degrees of rotation. This is what that tool is for, it allows you to add addition rotation of torque to the bolt.
@@SimpleCarGuy Oh, I understood the additional angular torque. I meant, just the actual bendy arm and gator clip on the angle indicator tool. Not sure of its purpose.
Hi! Yes, it's possible. Depending on the model of the car, you may need to drop the subframe (it's like 8 bolts) if you want to do the timing chain at the same time and you'll have to remove the radiator fan and a few things on top of the engine to remove the valve cover. I go into a little bit of detail in the video on the timing chain: ua-cam.com/video/-apNebfNCMA/v-deo.html Thanks for watching.
That’s the idea. If it’s done well, it’ll be almost like new. Obviously tolerances won’t be a as good as factory. In some cases, you can upgrade components along the way and make it even better than new. Thanks for watching!
Can you suggest where i can get a 2012 bmw 335i service repair manual? I also have an engine to rebuild here in my house. It’s so hard to find engine rebuilder in NC. Thank you much in advance
I had purchased a 2011 BMW 535i, with an N55 engine. The engine has rattlely noise when I start it, and scanner shows Camshaft Retard, Bank A & B error code. I've replaced VANOS Solenoid valves to no avail. I've just replaced spark plugs, and will be checking the timing chain. Hopefully these last two will at least provide an improvement to the engine.
@@brewyawn3394not good. I turned the engine manually when checking the timing chain. Put valve cover back on, engine oil etc, started the engine, cranks but won't start.
That measures the tolerances to make sure they are in spec. If the ‘squished’ plastigage is too thick or thin I wouldn’t proceed with the install and have to get different bearing etc.
I just bought the same exact car but convertible and I just found out there’s oil leaks basically oil gets mix with the coolant I spent all the money on this car now I don’t know what to do. I feel like I wanna cry
Hi ! Thank you for this awesome content ! Really enjoyed watching this !

(I mean why not larger or tighter eventually) 2) around 16'14" or some few moments you've used a torque wrench to tighten that long bolt then you kept tightening it with a circle paper with angle => is there any reason/recommandation for that extra tightening such I've seen that no extra strengh should be put on after the torque wrench click ? Sorry if those questions have already been asked but I didn't see them prior and for sure, thank you for the questions ! Cheers !🙌
angle torquing is simply a more precise way of measuring ... so its not off. 70nm would be something like double that by doing 360. gap clearance is chosen by piston manufacturer. read manual for proper end gap... most brands are a little different than stock.
And, never use a power tool to wind down mains caps bolts! the same goes for cylinder head bolts, always do by hand, but check the bolt threads beforehand.
That bolt is crazy! It's torqued up to 100Nm and then ANOTHER 270 degrees of ration after!! In the service manual, BMW states: "Breakaway torque of the central bolt > 600 Newton metres"
I don't do this as a job, I just did it to see if I can rebuild an engine. The second engine I bought was $300 as it had a spun bearing which required a full rebuild because the crankshaft was damaged. It's not really worth it to pay someone to rebuild it as it's cheaper to buy a used engine.
That was all parts of the engine.. the rod bearing spun and seized on the crankshaft and then the rod broke and sent metal pieces flying throughout the engine.

I used newtis and BMW software at the time.
One of your pistons did not get a bearing... If am not wrong
Clips were slightly out of order. I, of course, installed the bearing just like the rest. Engine has been running for 2-ish years
I never hear good Things about the n55 are they really that bad?
They are not a bad engine, but people tune them and drive them hard. I have a video on all problems to expect on these engines.
How much replacement engine n55 go for these days?
Probably around $4k, more with lower miles.

Yep, still in my car
My M57 just spun a bearing so am considering rebuilding it. It's not cheap. Would you rebuild over finding a used engine?
So much work.
Torque specs ? Where did you get them for the entire assembly
they have things called service manuals. amazing, really. tells you how to put everything back together.
You did injector the bed plate sealant wrong. Could possibly leak down the road.
