Valeo SMF non-SAC kit

edit: meant to include this more thorough review:
http://forum.e46fanatics.com/showthread.php?t=958649

I replaced my stock DMF and clutch with a Valeo SMF kit early this year, around 175,000 miles. I have about 4,000 on the kit so far and love the engagement, feel, and responsiveness (granted I don't know what the car felt like pre-172,000 miles... my only experience was with the worn DMF...see 3rd video).

As the weather warmed I did notice some gear (lash) rattle (clutch chatter to some), and wanted to post video(s) to warn potential Valeo customers, and to get people's thoughts on the severity. I can only really hear it in neutral with the clutch pedal out; inside the car, with windows up, it is not very apparent at all. So, it's not a nuisance, but is it a long term problem? I didn't expect this much noise from a sprung clutch disk and flywheel nearly as heavy as stock.

My parents are from the midwest, but I am in the south... was feeling it today, so excuse the accent, haha!

outside:


inside car, but door open:


tired old DMF!!!


part numbers:
Valeo 52401220 Clutch Conversion Kit

Below is for reference. I purchased the kit from FCP Euro, not Amazon...

I don't think that that's clutch "rattle".

I've had the UUC single disc LTW clutch kit ($1098) which weighed in at 24.5 lbs, it had what I'd refer to as typical clutch rattle. Using UUC's recommended clutch fluid "cocktail", my rattle got better, as in not as much chatter/rattle.

I then moved on to a UUC Twin disc LTW clutch setup, it weighed in at 25.5 lbs, this one extra pound of weight lessened the chatter/rattle by close to 50%. As a reference the Stock OE clutch & flywheel weigh in at roughly ~38 lbs, IIRC your Valeo kit weighs in at roughly ~37 lbs.

So to my ears, that does't sound like rattle to me. Maybe a bad throw out bearing ??

Thanks. I considered that... didn't want to... My friend has a shop and did the install... He may have mentioned the provided throw out bearing didn't look great. I'll have him give it a listen.

The faint rattle I occasionally hear with my Valeo kit doesn't sound like that at all. I think you've got something else going on, as Rob43 mentioned.

"IF" this problem of yours is really a noisy TOB, assuming it doesn't grenade it could easily go for years without any problems. So you could live with this problem year after year with no worries.

If it was the throw out bearing, you'd hear the noise when you press in the clutch. If the rattle goes down when A/C load is off, then it's clutch rattle.

^yes, I never noticed the noise before... if I had I would think maybe a front bearing in the transmission... I also posted back on the other thread:

^Sorry, a year late I do not....

I was watching some motortrend videos and found the exact sound of this kit... Don't feel so bad about it now, but upset Valeo never responded to multiple polite inquiries... They could have told me "it's just a Porshe noise" (kidding). Have to skip to 7:42, my timed link did not work.
