Slightly Slipping clutch

Postby miyoochionnow » Mon Jun 11, 2018 8:18 pm

I have a 110k g35 sport 6 MT 2007 4 door sedan. The car is usually a long distance car on generally straight roads with very little heavy traffic/city drives. Recently, going into 2nd and 3rd gear i feel like there is a little bit of slipping. seriously EVER SO SLIGHTLY the RPM's jump up and down a little. The clutch still feels tight and does not feel loose when pushed all the way down. I am not the 1st owner so I am not sure of when, if ever, the clutch/flywheel had been replaced before. In addition to this, when my car starts there is a slight rattling sound. Sometimes when I press the clutch down fully i hear a whirring sound but no burning smoking smell. I was told that this might be because of the throwout bearing on my particular model. There doesn't seem to be any leakage of fluid from the clutch so i THINK the clutch slave is intact but the fluid could definitely use a flush.

My question is there anything i should do prior to taking it in to get inspected? I was planning on getting an EF, XTR or Valeo clutch kit off ebay and bringing it in. Should i wait for them to do a diagnosis or do i need to have the parts when they look at the car? I'm not 100% sure that the throwout bearing is the reason for the car making that rattling sound either, so i am hesitant in buying another throwout bearing too. Also, any info about which stage clutch would be best for a daily car because those stages are a little confusing. THANKS!

Any insight would be great as this is my first MT car that I have needed to replace the clutch system and i really enjoy this car too ^O^

Welcome aboard!

Sounds to me like some wear at the pilot bearing or the throwout bearing. At 110k miles, it's probably due anyway, and that should all be done when the clutch is replaced. Plan on a replacement flywheel and do a full flush at the same time. No reason to try and take shortcuts, especially if she had a hard life with her prior owner(s).

A stock replacement is fine.

I wouldn't worry about the slave cylinder. If you have a problem later it's fairly easy to replace.

Correct. And it's not expensive, so I'd replace that as well - then you don't have to re-bleed the system, and it's tired by now.
