How To Replace Your Rod Bearings At Home | BMW N54 DIY

[@adamjones9648]

You are the reason I still have my n54, what a service you provide to all of us!

[@agusgolturbo]

you should accept donations and use them to reach/teach the limit of this n54.

[@kyleadams4156]

So pumped you dropped this. Just noticed a rod bearing issue when I did my oil pan gasket. Your videos have walked me though every thing I've done to my car. Inlets outlets upgraded twins etc I've done almost everything you've done. You're a savior man keep it up

[@jameswross2003]

Donation sent. Much appreciated for all the videos you've made in the past.

[@VehicularDIY]

Thank you very much!

[@deejaymikeskillz]

Dude good stuff. Don't be bashful about taking donations, you kill the DIY game for the N54. You deserve more than most. I'm a Helicopter Technician, and I'd be scared to tackle this one on my garage floor! And I rebuild jet engines all the time ! Lol. Thanks for your service dude !

[@nathanross963]

Love the content. I don’t think asking for donations is a bad look. I say if you have the money to support channels you like to watch then go for it.

[@SaroG]

This is one of your best videos to date: your concise explanations coupled with a quality camera deliver a fantastic guide/presentation. The N54 isn't exactly a cheap platform (which is a good thing) so it's not always feasible to dump money into it. There's no shame in asking for donations; a large majority of channels do it (re: Patreon) so no one can judge you for asking. You're very down to earth; a trait that clearly shines through ALL your videos. All your supporters & viewers know you're doing this because you enjoy it and want to share your knowledge with the rest of the world. Please keep going for as long as you can, we've got your back!

[@VehicularDIY]

Thank you!

Video quality, the information, the humble narrative, the details. It is just very good content!!

[@_Kaurus]

Vehicular DIY, I think you should re-asses your ideas of not taking funding from folks. Money is just money, and if someone really appreciates your effort and deems your time of value to them, they should be able to donate to you. It's their way of giving back and you true deserve the cash. Your videos are amazing to this community. Thank you.

I own both a 335i N54 and a F10 M5 and I wish there was even 1/3 of the content you put out for the N54 for the S63 platform. I have never donated to your channel but I have relied on it so much I feel like I owe you.. and I would have no issues donating to see some more of this content.. (and maybe one day hopefully similar content on the S63tu ??? )

[@VehicularDIY]

Not sure if you had seen but a few months back I picked up a 2015 XDrive50i with the N63TU engine. It's my wife's daily driver. It's got 62k miles and I'm sure it'll require a bunch of DIYs. Mechanically it shares some similarities to the S63TU.

[@alexgonzalez7395]

I’m running a st n54 setup. I ended up spinning a bearing. I heard it and shut it off. I changed my rod bearings with race acl with arp rod bolts. This was 4 months ago and it is still strong. Good thing the crank was still good. Saved a lot of money and motor 😂

[@Randymanrockssocks]

Still no bmw. Still watching all your videos

[@tomtom255]

Your stock bearings looked excellent, especially considering the mileage and power the car is making. Just goes to show you how important proper maintenance is and the difference it makes over the life of the engine. I've heard nothing but good things about King bearings, but then again your stock bearings even with the tighter factory clearance.... I'm excited to see the car up and running again.

[@brendenbanks9293]

are you high? some of his stock bearings were smeared from oil starvation and the other were heavily worn and some scored from debris. They looked horrible.

Looks amazing. Thank you for all your hard work. Is it possible to briefly address the pros and cons of pulling the engine out and doing the work on a stand?

[@VehicularDIY]

Sure I can include a brief statement in the next video when I'm doing the chains etc.

[@JrIza_914]

i think the biggest con would be time it take to remove and install engine, pulling these engines aren't hard if you have the right tools, it's just time consuming. Pros would be space and you can change other components much easier while its out and you're not on your back.

[@oshtheld]

Very clean video work, appreciate the 4K uploads.

[@kenvanbuskirk7034]

If the cam tray idea works out with the amount of boost you are running you should also install ARP head-studs. Nothing like investing the time,money and effort that you have to only go a few more miles to lose a head-gasket

I had to change my rob bearings about 3 months ago as well and i went with king bearings. Really happy to see u using the same ones

[@hinse4231]

How’d it go?

[@humble1835]

Little trick for doing this, once the cap is removed. Screw in one of the bolts into the rod. This gives you something to manipulate the upper with. In the middle of a rebuild plus some 19t's so I'll see you next payday. 👍

Have you considered changing your crankshaft pulley to one for a manual transmission. Don’t think your failure was due to that but make me wonder if it will cause vibrations.

[@VehicularDIY]

Hey, I didn't really look into it. I just read that the auto one was a little heavier so I figured it wouldn't be an issue. Given the autos don't have the mass of the flywheel they used the crank pulley to counter the forces.

[@Koolicyde]

[@toddbookout3845]

Great vid as usual!! Great service for us n54/n55 guys!!

[@luyanoH]

As usual your content is pure gold for DIY guys ( like me ). MY helix has been making a really weird sound like the chain is shaking badly ( Specially when the AC is on...) I'll be doing a oil change soon and i am going to try to stick a camera thru the oil pan plug. Hopefully i wont see the plastic guides sitting at the bottom of the pan.......... after that it will be time to take out the motor and build it up. So far i have been pushing 32 PSI ( probably pushing close to 800 WHP since i made 710 WHP at 28 PSI with a 6870 docrace ) over 30 passes and the car is holding well.

[@VehicularDIY]

Damn 32 psi, nice. You running the 4x kit?

[@luyanoH]

@@VehicularDIY 3x kit. but the more i think about the really high pitch sharping noise, the more i think i am going to pieces at the bottom of the pan ( sound like the one you get when you first start the car but like at least 3 times faster ). I am using the JB4 and the timing is like 3 or 4, i rather have low timing with high boost than aggressive 9 or 10 with lower boost.

[@luyanoH]

Also, i forgot to mention that i am using port injection as well with e85 ( usually i get between e76 and e81 at the pump )

[@Fosgen]

If you use some MoS2 in engine oil, next time you will see nice green layer of MoS2 on crank bearing faces.

[@machtschnell7452]

I thought the color bearing code is embossed on the crankshaft? Plastigauge obviates that anyway. Commendably thorough. Accepting contributions for possibly doing unnecessary cam tray overhaul is totally appropriate. When did Teflon seals start being used?

[@VehicularDIY]

You're right, the block has the info for the main bearings.

[@bigdeal87]

Where should i find that color on the block?

[@dappa311]

I have a question, why do some N55's engine all of a sudden have spun rod bearings, I hear stories about engines failing randomly even when the oil changes are done on time? Should you change rod bearings on a N55 that has lets say 126k miles on it but runs fine , no issues? I have. 2012 BMW X6 , beautiful truck I have it on 22's , love the styling and look, but worried I might be driving one day and the engine goes caput. It drives fine and idles smooth , no noise or knocks, I use Liquid Moly 5-40 and Installed a metal oil filter housing. Truck runs great , just would like to know if changing the rod bearings is something I should look into as a maintenance and if so what type or brand should I get to give a little more clearance to avoid future problems? Looking to keep for another few years and by the way what causes these random failures if you know?

[@samthing4thetrack806]

this is good many S54 folks suprisingly don't check with plastigauge or some other method for clearance

[@johnarussoii]

What about balance of the rotating assembly? Are the new bearing weights identical to the old so you can assume the assembly will still be in balance?

Could you, please, help me understand how much i have to torque my rod bolts on s63 engine..on ista i have two options 1az and 2 az. the 1az have 3 steps torque plus angle to 70 degrees and the 2az it's with 3 times loosening the bolt. Thank you very much for your help!

[@trainwreck5973]

Can you do this on a car with rod knock. I might have caught it early. Just did my ofhg n55. Primed the oil and still developed a slight knock

[@tankandjoyvlogs8328]

Hey what happens if it’s out of what it’s supposed to be? Like if it’s too much or not tight enough? What would be the next move. Just asking because I’m going to do this soon

[@colinwie9192]

Question for ya, have you considered switching to an Ester base oil, particularly a 10w-60 weight considering you mentioned the aftermarket rod bearings beings slightly "looser", and not to forget you've still got original main bearings in a 200k mile "HP" motor. Not that there's anything wrong with Polyalphaolefin oils (group 4 oils), but a Polyolester oil (group 5 oil) might be very advisable, in my opinion.

[@VehicularDIY]

From what I've read running anything thicker than 5w40 might be a little touch on the stock oiling system.

[@sydneyNemesis101]

[@hans-ericoberg6324]

Hi! I have change my rod bearings at my car (E92 335i N54 2007) this week and my car has 220000km so I was not shure what to expect but my old rodbearings looks still ok and the crankshaft journals look like new but I decide to put in some new oem bearings anyway. I mesaure the old bearing clearance with plastigage and it was .045mm and the new bearing clearance .051mm so it seems that BMW has increased clearance at this bearings today. My crankshaft was marked with rrrrrr so I put in six new red ones in the connecting rod cap and the yellow one in the connecting rod. I thought this might be good to know for you just to have as a reference.

[@david_vash]

I have a 2011 535i Xdrive. Will I be able to do this job at home do you think? It’ll be my first time doing this job.

[@5300aikon]

Is the plastigauge come with the bearing kit?

[@johnarussoii]

Any ideas on what causes the bearing failure? I am having an oil analysis done, as I am suspecting oil contamination may be the cause and I want to fix whatever caused the failure before I replace my bearings. And if I’m hearing the rod knock, which just started so I parked the car, what are the chances I haven’t damaged the journals?

[@gazjacko6695]

Hi do the rod bearings and mains need to go in a certain position or are they all the same size

Why havent you decided to go with upgraded crank hub solution like VTT makes one with splines? Since you making all this power, and its a weak area for n54/n55/s55.

[@VehicularDIY]

Mostly cost, the issue isn't as prevalent on the N54 so I am upgrading to BMW's latest solution for the S55 which I expect to be an improvement over what my N54 came with.

I've noticed in previous vids that you have used BMS cowl filters. Living in TX do you find that a lot of water gets down into the bay, especially onto the downpipes and DME area? I also live in TX and recently bought an e90 335i, removed the cowl lastnight and then it started raining. I noticed a pool of water on top of the engine cover in the morning.

[@andrewtravers7964]

Are u going to change main bearing to?

[@VehicularDIY]

No as that involve removing the engine, this car uses a bed plate to hold in the crankshaft. One of the reasons it's so strong but at the same time you can't change the mains with the engine in the car.

[@VehicularDIY]

I'd look into ACL bearings from what I've been told they are a safe bet.

[@Fix_It_Again_Tony]

Great video. What is the recommend rod bearing clearance? TIS doesn't seem to list this info. It just instructs you to install the proper color bearings based on the letter designation for each journal. During your research did you find any information about mixing and matching the stock bearings (yellow with blue or violet with red) to tune the clearance to be a little on the loose side? You mentioned cylinder 4 seems to be the worst for rod bearing wear. Is this some sort of oiling issue common to all N54s?

[@VehicularDIY]

Thanks, 0.20mm to 0.046 mm. I didn't as I knew that going with King aftermarket bearings would net a larger clearance than factory. I ended up around at 0.038 to 0.040 so still within factory specs but on the looser side which is good as I run thicker 5W40 oil. Some cars end up out of spec at round 0.050 but still acceptable. So my crank journals were on the larger side. I don't think it's an oiling issue but it's the cylinder that is most likely to experience noise and excess heat from the looks of it so it just lives a harder life and puts more strain on the bearing.

[@DailyDriverTracking]

I'm using WPC treated stock color coded bearings with about .050 clearance. No problems so far with hard track use.

[@Fix_It_Again_Tony]

@@DailyDriverTracking What oil? Are main and rod bearings the same clearance?

[@DailyDriverTracking]

@@Fix_It_Again_Tony I've been using Liqui Moly w/Molygen 5W40. The WPC bearings are stock bearings in the stock color size, they are bead blasted so they may have a slight increase in clearance. While the usage of my car is much harsher on the track, the power is tuned conservatively to 470whp. My experience with new babbitt bearings is that bearings run much cooler with a little more clearance and are less likely to fail. Worn bearings with more clearance lose their profile and fail. New bearings that are too tight will overheat and fail.

[@Jaylakhaili]

What was the reason you had to change them? Maintenance purpose or rod knock

[@VehicularDIY]

I had my oil pump chain tensioner so I went in there to change them as a precaution. No rod knock.

[@FranciscoTorres-cy4sd]

do the king bearings that you used fit N55 engines? On ecs tuning it says they dont fit, however i thought that n54 bearings work on n55 engines. Just wanted to know if u knew the answer

[@VehicularDIY]

Yes they fit the N55B30 as well.

[@matthewweisdorfer7757]

Whey were the 4 ASA bolts for? Also, did you use oil in the new Rod bolts or assembly lube? I know you used oil on the old bolts to check the plasti-gauge.

[@VehicularDIY]

I used oil both on the old and new bolts. They say avoid assembly lubes to coat the bolts for torqueing. Some assembly lubes contain molybdenum which would really throw off the torque. A high quality motor oil is fine. The 4 asa bolts?

[@matthewweisdorfer7757]

Vehicular DIY ASA Bolts part numbers 07129905738, 11417549370 - what do those go to?

[@nswiss19751]

What do u do if the bearings are too tight or loose?

[@VehicularDIY]

If they are too tight you'd have to stop and get another set of bearings. If they are too loose then maybe the crankshaft has been machined in the past and you need to look into over sized bearings. Pretty unlikely scenarios.

[@hanglin8563]

Just curious, what’s your bearing colors marked on the crankshaft?
