The noise you're describing after the conversion to a single mass flywheel (SMF) is "gearbox rattling". While your dual mass flywheel (DMF) was quite heavy and had big springs incorporated, the inertia kept the flywheel in motion and the spring took the impact of each ignition. Now that the SMF is light it slows down in between each ignition and there are no springs to cushion the impact of each ignition. So the gear wheels are making more forcefully contact while at low RPM. In order to reduce the amount of gearbox rattling you could increase the idle RPM or use thicker gearbox oil, but all in all it's the price to pay for a faster revving engine.
My daughter is 4. Love love loves working on "HER" 325I. hope her Intrest stays with her. Awesome to have a female mechanic. For her to watch with me. Keep up the great work. Thanks again. I think I see where she picking up that tongue out thing now 😜
Smart move replacing everything. That car has come so far since you got it. I like the way you’re approaching the build by replacing all the wear items and making sure everything is upgraded and done right.
Couple options to tame the chatter. #1. Change your trans fluid to Redline gear oil (1 quart 75w-140NS and the rest redline D4). This dramatically decreases the noise. #2. Get your ECU tuned so your idle is 1000rpm. You can test this by just revving the car to 1000rpm with the clutch out and see the difference. I have the same car, same clutch kit, and did both of the above. Didn’t make it go away, but 100% liveable now.
The rattle you are hearing now is the non dual mass flywheel. Now u don't have all that weight to absorb the vibration so u get that chatter. That's not just the BMW. That's for all cars with that type of setup. U will be fine.
I believe DKM makes a single mass iron flywheel as opposed to steel if you wish to further reduce chatter (I went with this for my e46 M3).. it's only a couple lbs lighter than the stock dual mass.. could also look into combining with a twin disc clutch which seems to have design integrations that help further reduce chatter issues.. not to mention the massive increase in torque capacity :)
That sounds is to be expected with a SMF. I installed a GripForce Stage 2 Clutch kit w SMF and Spring Loaded clutch disk in my E36. Get only the faintest bit of rattle. Highly recommend this kit.
You are it, great skills. I need to change mines too, just yesterday I can not shift into reverse, number 1 also is hard to shift to. So my question to you, why you think the noise is coming? Is it the performance model the reason. Also what was the total price for all the parts you replace. Thanks
Good work. It's always best to replace everything while the transmission is out. I've had good luck with Dawn dish soap for getting grease off after working on cars.
I have a 2004 325CI with tons of cold chatter when cold and the car was produced 4/2004 but the Valeo kit says up to 8/2003 so I'm stuck with another crappy DMF. Whish I could understand what the change is the prevents me from using the single flywheel kit.
I was hoping you were putting in a new friction plate at the least while the trans was out but never expected a new flywheel but dual mass is a fancy term for dual harmonic dampener and yeah your well versed in mechanical terms I'll quit and leave it alone
@@Gabby_Downing you should have change it also since you already brought down the transmission 🤣😂😂😂😝😝😝 it would have been much easier for you.... In my opinion..
Great job 👏 👍it always worries me when I fix or upgrade parts and afterwards I get new noises but I go with the "it should be fine" method as long as it still works normal and see what happens 😆 🤘 keep up the great work! 🤙🍻
I was SO WORRIED and upset when it was making all that chatter! Especially since it was almost 1am… but after some research it’s normal for a performance flywheel to have chatter when my oem flywheel is supposed to be a dual mass.
@@Gabby_Downing true that well im glad everything is working well keep up the great work 👍 💪 I look forward to seeing more videos of your progress on the car and also with the car as a driver🤘
The guy in the back was just watching you like wtf is wrong with this chick😂😂😂 but it's always good to have fun even if it's childish cause I do the same thing as well, all day every day😅 glad you got those old parts changed out, break in that clutch good, put a lot of miles on it and next drift event it'll be much better, that flywheel swap is gonna make a huge difference
hahaha I'm always having fun like that, I just finally caught it on camera! IDK howwww the Agile team deals with me lol. YES! I am loving the new clutch! Except for the noise, but totally worth it, I am excited to test it out drifting this weekend! I am being sure to break it in. 500 miles!

No. All this that you said is wrong. Do NEVER use LS fluid in a transmission.
Why? @@dabelu7165
your personality made this interesting to watch. very informative as well . thanks!

I just got the same exact kit in yesterday. Also doing everything while I'm in there. This is my first time doing a clutch! Hope it works

Try a Valeo single mass flywheel. I haven't had any issues with it.
Wish I could but my 325CI was produced 4/2004 and the Valeo kit says up to 08/2003 production. Whish I could understand what changed.
How much chatter does it have? Thinking of going with that one
Flywheel chatter is normal going from a heavy dual mass to a lightened single mass. How much chatter is normal? I don't know. =]
Good work. It's always best to replace everything while the transmission is out. I've had good luck with Dawn dish soap for getting grease off after working on cars.
Hey cool video!
I’m getting ready to install the same clutch today. How do you like it after all these months?
Good job 👏
Keep up the good work!
what was the torque spec on the flywheel bolts? asking 4 a friend
74ft lbs
You've taught me alot
I am about to buy this kit: is it good?
I am so impressed you work is very good
what is the brand of your new flywheel?
I thought this video was great when I raced a 69 chevelle SS396 a heavier flywheel gave more low end torque and I love Gabby
Amazing work! Keep it up! Big fan🙌

I’m sure you know that rattle is normal. Anything with a light weight flywheel gets noisy at idle like that. Does it in my Bimmer and RX7
How’s the clutch max clutch been so far?
i just changed my clutch and i rushed it im pretty sure i installed it backwards :(
good job youtube algorithm to bring me here... m in love with those deep blue eyes and that bimmer.....
Well played, class 👌🏴
Gonna have to come back to this tomorrow, got to go get some sleep, see later Gabby :-)
Your having way too much fun working on your car lol.
I need to replace the clutch in my e46 330i !, you wanna help ? Lol
Its a lightweight flywheel. Very common.
Carrier bearing is in center of driveshaft
Did you also Change the Transmission Oil?
I did not change the transmission fluid
@@Gabby_Downing ohhh when was the last time you top it up with a new fluid?
@@Hardee03 🤫 🤫 🤷🏼♀️ 😂😂😂😂😂

Lucky people, they don't know problems with rusty bolts
Bruh. My first several cars were TERRIBLE with rust. For this bmw I specifically went and bought something without rust.
It's normal but disturbing that's why I kept the original flywheel
💖💖💖👍👍👍
Find a German mechanic; get his/her opinion......Gabby - German cars can be very particular
Hey, hi, how's it goin?, fellow manual e46 owner, anyways me, you, tandem, dinner, wine, tandem, wine. anytime anywhere lmk

Her energy is lol.
haha nice machine gun noise
I was really having a good time. It was so late but everything was going smoothly 😂
Wow, you're extremely beautiful! Good video too ;)
Such a beautiful girl… I love me my heavy dual mass tho 💕
She needs more grease on her face as a mechanic for 40 yrs I never covered my face in makeup like that lol
