That sucks. I really hope your channel gets more views, I found you through the LS swap video and I think you/your friend has the coolest e92 swap on the internet. Maybe make some more content with that car? I dont know, the way youtube works is really weird, how some people blow up and some people get few views. Its another single turbo guy I watch, who's very knowledgable and also has like no subs and views, I dont get it. Somehow full bolt on guys get all the attention
Bro that just happened to me, is a shit. I didnt know about this issue with the crack hub in the n54 because is not so common as the s55 engines. Now i had to buy an other entire engine and do the crank hub job to this as is not happening any more. All my support to you bro!
people need to know 1st mod to do stock or not is upgraded crank hub. mine slipped even though i was stock. damn bmw for making that a weak point. luckily timing is easy to do. new chain with new guides and one piece crank hub is sleep easy nows.
Wish you got the attention you deserve on RUclips. Your reflex Flashing video help me a lot. Sorry to see this happen and I hope you come back stronger soon!
So this happened even after you put in the crank capture? Too much torque from the diff? How much HP were you pushing at the time? I'm going single in my e92 automatic, sure I might not need to worry, especially if I'm usually doing rolling pulls but it worries me if this can happen even with one... definitely gonna get one for when I do my seal guard, I've been putting it off since I replaced my power steering pulley (got chewed up from potholes) and fixed my oil filter housing leak, but gonna be doing a major overhaul when swapping the single turbo in so I'm gonna add that to this long list for sure. Still makes me nervous if it can still break and slip the hub. I guess I'll just have to get a moderate tune until I'm ready to completely rebuild the engine and go with a splined or pinned hub.🤔 I don't like seeing fellow n54 friends have any sort of failures but thank you for putting it out there for everyone to be able to learn from these mishaps so it doesn't happen to others, taking one for the n54 team!
Yeah, even after the capture. That capture is only there to prevent the bolt from backing out, which wasn't my problem. I've been running the VTT Spline lock without any problems though
Sick, good to know, I just ordered up their valve cover and external pcv system for their Black Friday sales. Do you know or have had any experience with those? I know vtt has a... reputation... but those were probably still the most often purchased and available components. And I also have to say that they look like they would definitely look the nicest..
Spun a rod bearing on me f30 n55, sent it to be rebuilt. Over 4 months later (covid shit made the shop have to wait on parts) I got it back and local shop reinstalled along with pure stage 2 turbo. 600 miles went by and the car was running super strong, flashed xhp stage 3 after waiting for full break in and drove all day long it felt awesome. Shut it off and literally just started the car the next morning made it 20 ft and I got a power train error.. intake and exhaust cam out of tolerance. Pretty sure she spun the crank hub. Strange part is motor has 0 weird noises, idles and cruises perfectly fine just with reduced power from the dme. Sucks but we'll get the valve cover off and manually check timing. Best case scenario is putting timing back in spec and re torquing crank bolt along with adding a capture plate for further safety although I wish I had the funds to do a pinned hub. Unfortunately I'm $10k+ into the rebuild and ps2 along with other items I replaced for preventative maintenance while engine was out
Did you figure out what caused it same thing happened to my buddies big boost n55. Same codes we’re gonna try to retime it and put a new chain tensioner to see if it solves it before redoing the entire timing system. Cars got like 200,000 on it
@@mustafay4427 no I actually haven't yet to be honest, but at this point I'm more inclined to think I broke the valevtronic servomotor/eccentric shaft. We ruled out crank hub because the shop took off valve cover and they confirmed with the special tool that the car was not out of time. Very confusing as the codes have changed since when it first started having a problem. It also got worse when I drove it to the gas station to put new fuel in as well as get a data log for more Intel. For the first time since getting the error codes, it actually started running rough when this whole time it appeared to idle or cruise just fine. Had to end up pulling into parking lot because i wanted to shut it off for a minute, restarted and actually wouldnt even shift into drive, and shifter wasnt lit up even with car running. Towed to shop and see theres oil in the engine bay cant tell exactly where from with only a quick look at it. Have been too busy to continue deal with it and told shop to let it sit until we get a new gameplan. Long story short I think theres apparently the possibility of oil being able to get into a wire harness due to the breaking of servomotor/eccentric shaft and apparently make it down to the dme. Oh also I am now getting about 15 codes talking about canbus errors so it's not looking great. Either way I know I'm spending more money but I just need to fix it and enjoy the new turbo 😅
Dam so you’re saying I don’t get to see your ugly mug for a while? Shit keep at it man. Sometimes it takes a while for people to blow up. The wife and I are starting a cooking channel. Hopefully that blows up so I can afford to do a car channel lol 😂
Pretty sure this is what’s happened to me after doing all the common checks/replacements for 2A99, including new bearing ledges and seals… How has the rebuild been?
Damn dude rip, its always something on my mind but until it happens to you, you try not to worry to much about it something im gonna have to look into continuing my n54
@@BuiltInTheRain yea man I feel that mind set but watching your video is getting me out of it I ain't at 600whp yet but I was planning to go speedtech full e85 lsd like you seems that should be done before going for big power if you want to be safe
Here is a idea....Stop Adding horse power TO MOTORS NOT DESIGNED TO HANDLE IT! YOU KNEW ITS NOT MADE FOR IT AND YOU BLAME THE ENGINEERING TEAM AT BMW CAUSE YOU CHOSE TO STILL DO SOMETHING THAT YOU KNEW WOULD BREAK IT!

Get a crank cap kit . It goes over the original crank bolt and locks it in place so it does not spin loose under throttle.
people need to know 1st mod to do stock or not is upgraded crank hub. mine slipped even though i was stock. damn bmw for making that a weak point. luckily timing is easy to do. new chain with new guides and one piece crank hub is sleep easy nows.
Seriously though... I even knew it was a thing, but thought "it would be rare anyways since it's not a huge issue on n54's"
Fuck man I'm sorry. new sub here. Please show us the crank hub install.
Wish you got the attention you deserve on RUclips. Your reflex Flashing video help me a lot. Sorry to see this happen and I hope you come back stronger soon!
Definitely not giving up on this build. In it for life
Hey bro did you have the Crank Seal Guard installed when this happened?

What made you go rebuild instead of just buying a new motor?

Been up and running for a while!
@@BuiltInTheRain Nice, wish I could say the same haha.
Bad luck, but don’t give up, keep the build going.
Got er back up and running. Tinkering with the little gremlins at the moment
The fact you did an 8.8 diff before the crank hub upgrade that's on you lmao🤡
you're not wrong
@@BuiltInTheRain good luck on the build brotha
@@335CICHLID thanks for the love bro
Damn dude rip, its always something on my mind but until it happens to you, you try not to worry to much about it something im gonna have to look into continuing my n54
Bro, I had the same exact thinking process. I promise.
If you're pursuing 600+whp, I recommend a crank hub fix. Either splined or pinned.
@@BuiltInTheRain yea man I feel that mind set but watching your video is getting me out of it I ain't at 600whp yet but I was planning to go speedtech full e85 lsd like you seems that should be done before going for big power if you want to be safe
Suck cuz its a shitty job youd rather avoid
that sucks dude...
We’re you running the oem crank hub?
Yes, but not anymore
@@BuiltInTheRain Did you have the capture already and it slipped?
@@chrisbradley3224 yes I had the capture and still had a slip
Keep grinding that’s all
Yes SIR!

Are you saying that it’s not stupid to pin a crank hub? Stock S55’s have this issue all the time
Time to go upgraded bottom end broo.
I will be patient rebuilding the motor that slipped timing and be throwing in another stock motor in the meantime :) I still want to drive this thing
