You are an invaluable member of the DIY bmw community. Even if you aren't getting the views you used to, just know that we still appreciate you more than ever. Thank you for everything you've done for us

Jason your presentational style really is one of the best on KZfaq. Travels really well globally. Pleasure to watch.

Thank you for showing your mistakes. That makes the rest of us feel better, knowing that a master mechanic makes mistakes too.

Thank you so much for sharing the difficulties of the job. It’s a massive help

Those aluminum torque to yield bolts are notorious for breaking on the way out if put under any stress say with an impact or something. Did my oil pan and rear main seal on the E93 and got luck, no broken bolts. Nice video.

Not a lot of room to work. You show great patience.

Great video! First of all - you looking great when lose weight and I have 1 Question - "what`s the difference between 3 hours work on the engine and 3 days work on the engine?" Yeah - exactly what you show us. "One broken stud or bolt". I can feel your pain at this moment. Thanks for keeping that staff in your videos. Im still on m54 with 80k and planning to keep it forever =) but that`s great to see DIY videos for other engines on your channel.

Really glad you made this vid! I commented on another serpentine belt shred vid you had uploaded about installing this.. I wish I'd known about this prior to it happening, but thank God I dodged a bullet.. to reiterate to everyone who owns an N52/N54/N55, you must get this done ASAP.. and YES, this DOES affect N55 as the dampener design is essentially the same as prev gens. Be sure to install the crank bolt capture while you're at it, 2 birds with 1 stone; while I'm running MHD Stage 2+ which is nothing super crazy, it's nice to have that peace of mind. Why BMW had to change the design of the crank dampener is beyond me; my S54 in the e46 M3 has it done right.. the dampener covers the front main seal, acting as a seal guard, while the pulley portion is installed on the outside. Love that ATI makes a super damper for the S54 for which I'm using, thus it can be rebuilt over time for much cheaper than a full out OE dampener replacement. Just wish they had one for the N55! And you gotta love when BMW decides to use aluminum one-time-use bolts.. again, love the M3, oil pan bolts aren't anything like this.. the Motorsport guys during that era knew what they were doing, and I very much miss it!

Just wanted to say, I appreciate the E90 videos. I learn a lot and appreciate the insights you have and the style it's presented in, if that makes sense (no BS, just slangn tools). Happy I found you. Keep it up!

Thank you. I will have to add one of those crank seal guards myself. Probably not needed with all leaks fixed and the correct (updated) subframe and/or the aluminium power steering pulley. But better to be safe than sorry. Keep the N54 videos coming. They have been great so far.

Oh my heart felt that bolt when it broke! Oh the hate at that point is Geiger counter measurable. I obviously am not there to see how this is but i did watch another video where the guy did it with just a regular ratchet (Non powered) and had no probs. So we are all hoping this won't happen to us. LOL. Great job no matter!

Kudos to you my firend for sharing this informative video. Was pleased to learn about the potenital pitfalls of the snapped bolt and the misalignment of the crank bolt and the slotted holes in the guard. All things considered, and I'm not gong to be adding silly HP to my car, I'm going to do the same and fit the seal guard but not the crank bolt guard.

Replacing the pulley that should have ribs is so so important, especially if the car is enjoyed to it's fullest potential as a dance partner, part number to do so is Dayco 89008

Jason...I just installed mine on out F15 N55 today, the belt guard. Now, I have a peace of mind. Thanks for your help. I was afraid of breaking the aluminum bolts, but they came off good!

Thank you Jason for this video. Just when you think things are going good and then something snaps. Happened to me one to many times.

Always learning, another brilliant demonstration.

I thought I was on the wrong channel hadnt watched in a while new man haha. Congrats on the weight loss

Did a belt job on 2013 x5 due to it shredding and luckily somewhere in the back of my head I remembered something i had read that Mentioned about the crank seal. Pulled the crank pulley off and it quickly turned into dropping the pan and oil pick up to remove all the pieces of belt that got sucked in.

I watch your videos for my e46, and now for my 335i too

Thanks for all the videos. Ive noticed that I’ve never heard you mention FCP euro for BmW parts. I’ve been using them since I got my E46 325i and have been able to replace and restore everything with their lifetime warranty. Even replacing my oil for free! I know you’re far in CA , they’re on CT but they ship fast. They usually carry all OEM stuff or at least OE. Btw You’re looking great and it’s awesome to see the progress you make on all your BMW’s and your own know how over the years. You’ve saved me a lot of time and money!

Glad to see your channel coming back after such a long hiatus. I notice you look much more energetic after losing some weight. Congratulations! Will you make videos on how you achieve this?

you also have to be careful, if you loosen the screw at an angle, the screw may get stuck in the thread and destroy the thread. In that case an easy out doesn't help anymore. Soft aluminium😐

That crankshaft stub bolt is specified at 300 Nm, which is just crazy high. I'm considering the addition of one of these guards after replacing the front seal on an E60/N52, and was going to time the engine and remove the stub shaft to clean it up and reduce the chance of future leaks. But when I saw that toque spec, I figure I'll just leave that stub shaft alone!!

Huge respect to you man you’ve saved me many times!!

Hi Mr Jasonwe are so happy to have you are making a N54 content

Dude, that's the cleanest engine bay I have seen, how 🤔 did you get it that clean, nice!

Great job getting that broken bolt out.

excellent work and explanation in real life. 100-100 i do NOT use any impact or power tools on my BMW . aluminum bolts are not a good idea and i try to stay away from twisting of any bolt.... so i go easy and slow (and scared)... and surely do not want to do things over again and again...aluminum bolts?? ( i have to do the front engine seal on my 2013 x5 35i ... not looking forward to it at all... the thing is ...leave it to these engineers to complicate these vehicles!!.grrrrrrrr great video!!

Thanks for sharing this information I am doing a valve cover gasket job on my car and when I removed the cover I saw parts of a belt that slipped out before, also I had a p0012 code I think that’s what caused the code 🤷🏻‍♂️🤷🏻‍♂️ after I finish the job I will find out😅

PSA: Check your power steering pump bolts. Mine worked themselves loose, which caused my serpentine belt to fall off.

Was hoping you had a full timing chain tutorial video!! Really need help with this , in the middle of working on it

I have both installed on my 335 n 54 and it's a life insurance so install both the crank seal capture too.

That’s the best shot of the rubber grommet on the fan that I’ve seen, actually lit up. I’m familiar with it, but on behalf of the newbies, thanks.

Man,you lost a lot of pounds Jason. Nice to see you again:)

thanks so much for that information, great job!

Similar issue to the corvette c5 harmonic balancer wobbling problem. But this preventative method is much easier to install than fixing the crank shaft seal.

great vid super informative and straightforward

ATF cooler lines in the way? I think it’s time for a manual swap 👀 long time viewer, I did a e46 manual swap thanks to your guidance.

Good job 👍🏼 I will be coming back to see this video again

14:13 que the “curb your” meme music😂😂😂

Great video, Jason. Thanks for sharing!

YOU ARE THE BEST ON KZfaq

The bolt broke…….I felt that pain!

Have a great weekend and thanks for the video.

Very helpful and solid education. Thanks.

I seen a change in your face I hope your healthy man

LOL, i love those bolts, wrenching in a nutshell, I left my AC compressor with 2 bolts with one of those bolts :D

When I was changing the water pump on my 535, everything was going way too smoothly. I went to tighten the last bolt and broke the head off! Holy s#!t was I mad… Ha, still get a little mad just thinking about it lol

wish I'd known about this when I swapped engine (x3/n52) last year. Had to replace timing chain guide and redo front seal, timing and crank bolt, quite a job, particularly the crank bolt. wondered at the time if there was a way to protect the motor from the infamous belt suck in. This looks like its not too hard (with the caveat on the alum bolts).

Happens because you used a power tool on aluminum bolts, you were supposed to loosen by hand.

Yes, you look good bro

I have a video of what happens inside the engine when the belt gets sucked in there.

Good to know!

That's a cool little protector. I'd be the one who that bolt would snap off for too. Nice video.

Thanks for this video Jason! This is next on our N55 X5 to-do list. I was not aware of the crank bolt "lock" that didn't fit. I'm curious if you tried to 'clock' it to get the crank bolt holes to line up? Sorry about the bolt breaking.....now that concerns me. But it really is a great peace of mind & insurance! Especially seeing the old belt you pulled off when you got this car. I remember some years back when I was replacing the clutch in my E34 '92 535i, the pressure plate retaining screws were a soft socket button head & the 1st one I tried simply remove stripped the hex out. The trick there was to give the ratchet a 'POP' to break it free instead of trying to muscle it off. A hard lesson! Then replace with class 8 socket heads, similar to the 2 you used on the seal guard.

Are you sure those two aluminum bolts don’t have to be angle torqued ? Every aluminum bolt on my bmw that I have come across so far had to be angle torqued to 90 or 180 degrees.

Looking good!!

Always love your videos … ever gonna give updates on Instagram again?

I shredded a belt just dont want to pull the balancer and check. My crank guard could of worn down or been chewed when it chews a belt. It sheers off the engine side because of the balancer design.

is it normal for the top of the gaurd to bend forward? its almost an 1/8" away from the block when i torqued it

Thank you bro

Hi Jason!! I have a 2000 323i with a A5S360R GM TRANNY and according the dealer it takes ATF2. What oil do you recomend for a filter and fluid change? Do I go with the Castrol transmax import or the Valvoline ATF?

The aluminum bolts strike again! Are those new bolts steel?

You mentioned fragments getting In the oil pan is the strainer fine enough that the fragments don't circulate through the engine not sure how bad mine is yet

They must’ve used a little too much sealant during assembly because mine came out like butter when I did it a year ago

When the wheel moved, did the engine timing got affected ? You didn't say anything

I’ll buy that vtt hub bolt capture of off you..lmk ty

Hey bro do you have a video on a timing chain replacement on n54 , really need help on it

Whats the recommended torque spec on the 6 bolts for the harmonic balancer / crank pulley?

Does the M52TU, M54, and the N52 also have this possible belt catastrophe ?

5:56 Marvin Gaye Let's Get It On.

You said the torque was 25 is that ft lbs? Thanks

working on cars NEVER goes to plan !

Thank you. Do you know if N52/51 is different? The part description specifically says N54.

on the m54 isnt there a new bolt that you put the wire through to stop it backing off?

What about on the N51?? Does this apply to the sulev?

That Fan probably comes out like 10 times a month lol

Bruh am i imagining or he lost some majure weight ? WHAT

It's unfortunate that the bolt holes didn't line up for you. That's the reason I haven't done this to my car-- I don't want to be stuck with something that won't fit without turning the crank bolt (I imagine it would be hard to turn AND require the purchase of a flywheel hold tool).. But I also wonder why VTT (or someone else) doesn't make a slightly modified version that will fit on all of the ones that the original one won't fit. If you offset the oblong bolt holes by 30 degrees (60 deg between holes in a 6 bolt circle, so half that), it seems you could make it work for all cars. Or make three versions offset by 20 degrees-- that should guarantee enough coverage along with enough material on the web to ensure strength. I'm looking at you Vargas.

50s kid is not that same guy. There is no charming anymore. I was wondering why it had happened and then I noticed he lost weight. In my opinion, being slim it is not his can of fish

hello can i contact with you about cooperation

es ist nicht gut alles mit dem Schrauber zu machen...

No blue locktight for upside down bolts .

Hes losing weight! Awsome what's your secret to help lose weight?

You have lost a lot of weight!

Garbage... don't use it if your car is making real power get a 2 pin crank hub... the belt guard works somewhat

Note : after all you see about the fan coming it will not. There still is a wire on the left to disconnect.
