Hey guys i just got a 90 240sx with a KA24E i started hearing a knocking sound coming from the bell housing and it only goes away when i depress the clutch. i think that it maybe the throttle bearings but i need to know how to fix or correct it.

throttle bearings? um probably not. throwout bearing/bushing probably.

Any updates on this, I have the same exact problem on my s13. I am about to go rip the tranny off, but I'll check back to see if anyone has any advise.

what kind of knocking sound? how do you know it's coming from the bell housing? have you noticed a decrease in performance?

manual or automatic? is it a rattle? if it's MT, the bolts that connect the flywheel to the clutch cover could have snapped and are just jingling around in your bellhousing.

if you're positive it's coming from the bellhousing, yeah just pull it and inspect. if you have the right equipment it'll take a couple hours.

post a video with sound

If it goes away when you press the clutch in then yes it is your throw out bearing, it is bad and needs to be replaced/lubed (better to replace.)
