ok guys i had a search but couldnt find anything helpful, everything is fine when im driving the car, the tranny is quiet, and smooth. At idle when i release the clutch in neutral at a full stop, theres a grinding/rattling noise.

I know many people have this noise but today, i took the car for a drive and hit full boost a few times and when i got home i could hear the noise a bit louder and almost clangy . The rev range effects it also, as when the car is in idle and the revs slightly increase with the aircon on, i cant hear the sound. Its like its a vibration noise or something?

I was told that it might be the throw out bearing but i dont really have a clue. Anyone with similar experience?

 

is this statement true? maybe i should get a new clutch? Would that fix it?

 

I had issues with my pilot bearing and throw out bearing. If I released the clutch, it would whine, and when I take off, it rattled a lot. And for my throw out bearing, it used to ticker sort of thing when my clutch was released and also made my clutch rattle. I replaced both when I replaced my clutch, and makes such a big difference! I thought, while I was down there, I might as well change the clutch so I didn't have to take the gearbox back out again...

Dennis,

 

I would agree with that. If it were the release bearing, it probably wouldn't sound "clangy'" since the release bearing is loaded when the clutch pedal is pressed. That, IMO, is a sound of something loose rattling around, and that fits the scenario of a failing/failed pilot bearing.

Someone could give the part N° of these famous throw-out bearings?

 

Are the pilot and throwout bearings expensive items?

 

Each cost about $20... its just a matter of the labour that's the expensive part as the throw out bearing (thrust bearing) is in the centre of the clutch. And the pilot bearing (spicket bearing) attaches to the eccentric shaft or however you spell it! The gearbox has to come out, including the clutch, not sure if the pilot bearing can be put on with the flywheel in or not? But that/s where it's expensive.
THat's why I replaced my clutch while I was there so I didn't have to do it again!

 

I have a really loud grinding/clanking noise coming from the engine/transmission area. It occurred initially when I released the clutch pedal but continued. I can also feel the vibration through the clutch pedal. Any recommendations would be much appreciated. I also have a video but not really sure how I can share it over the forum.

 

I'm also getting a really loud grinding/clangy sound coming from the transmission/engine interface area. It initially occurred when I released the clutch pedal. I can also feel the vibration through the clutch pedal. Any recommendations would be much appreciated as I'm pretty new to the rotary world.

 

That description sounds like a failing release bearing - that would cause noise & vibration while pedal pressure was being applied or released. It could also be too much play in the spline causing the disk to rattle, but that is not as common.

 

Obviously stop driving the car to minimize risk of damage to other components. And the transmission will have to be dropped and everything inspected.

 

At this point just plan on dropping the trans, the problems will be easy to spot then. It's most likely something with the clutch system - either the pressure plate, throwout bearing, or pilot bearing.

The FD is a fairly straight forward clutch job. There's very little rotary-specific. The pull type clutch is different but Evo's have them too, read up on how to disengage it before pulling the trans.

Thanks for the quick response! I understand that this thread is for 3rd generation Rx7s but I haven't been able to find anything similar to this issue described in the FCs (2nd generation) forum. I would imagine they are very similar. I was wondering if you know the brand/manufacture of the OEM clutch kit? I was looking into getting the Exedy clutch kit on Rockauto. Any recommendations would be much appreciated!

 

Really?
Try a re-check of the 2nd Gen section. Go to search, then to advance search and in ‘titles only’ and using the two words “clutch noise” I found 49 different threads. A quick glance suggested some with very similar complaints as yours.
You can also search using the term “exedy” or “exedy clutch”.

 

Thank you for the tip! I was able to search it successfully. I'll be using the advance search from now on.
