Here are the symptoms. I started up my CRX and noticed that when it's idling it makes almost a knocking sound. The sound goes away when I push the clutch in but comes back as I let it out. It sounds like it's on the right side around the belts but the sound doesn't match any of the belts movements? Any ideas?

 

check yer oil...

 

that's weird. The throwout bearing on mine makes a whizzing noise when its around 2 grand. and the right side is the transmission.
hmmm i'd say it was in the transmission. have a shop check it out. 99.9% of the time, they've heard it before and can immediately tell you what it is. and they dont charge for that

 

I bet its a input shaft bearing... not real expensive to fix, but you'll have to take apart the transmission.

 

Hahaha I got that exact same noise, I think I'll just ignore it and start work on the b20z swap. anyone know where to get a b20z block at a fair price?

 

i second that.

 

third that. had the same noise on my old d16 setup and when i took it apart that's what it was.

 

fourth that
my trow out bearing its fucked and it makes a sound when my clutch its out...

 

By a landslide.....I have the same problem with my 'rex...its a grinding bumping sound until the clutch is pushed in...it was that way when i bought it...plan to do a swap anyway.

Have fun

maybe ur clutch bolts or flywheel bolts came loose!!

 

ha it's amazing how many people here have that problem and just ignore it. Thanks for the help I'm going to go read up on how to fix it.

 

this may be pushing it, but i fifth that.
mine was making that exat same noise, this winter i ended up pulling the engine anyways, and i figured i might as well change that while i had it out. so i replaced the clutch, pressure plate and throwout bearing, no more knock

 

So would you guys suggest getting one of those Exedy clutch kits sold on ebay and installing that when I do my swap or should I just order the parts elsewhere?

 

It is most likely not a problem with the clutch, it is the input shaft bearing in the tranny

 

5th that mines fuct and it does the same

 

I dont trust those kits on ebay, you get what you pay for... I suggest the A.C.T. clutches, their street discs grab so nicely, get a lightweight fly wheel while you're at it just for quick rev response.

It is amazing how many people have that problem and ignore it, like me. My throwout bearing should hold up till next year, then i'll just replace it with whatever engine/transmission combo i want. Likely a GSR swap or another B16 built since they're just so much cheaper. I want the gear ratios of the GSR though, hate revving at 5 grand on the freeway.

 

this is what i was saying in my post then i think people got confused and thought it was the throwout bearing.

it is NOT the throwout bearing. its either the input chaft bearing or the differential bearing going bad causing the ring gear to rub on the transmission case. if is the ring gear rubbing you will see some small metal flakes in your tranny oil when you drain it.
