Default 2 noises noticed, any help?

I have 2 noises on my d21 with a ka that I am trying to figure out. One is from the flywheel/clutch area, and it sounds like a bearing turning with an occasional tap. The other is on startup and it is a clicking/rattling that goes away in 5 seconds, possibly starter?

Throwout bearing for the clutch and probably the timing chain rattle on startup.

I had that noise and tap for years and years. Also the rock tumbler sound.


The lifters and can make noise.


Later I ruined the input shaft bearing when the slave cylinder went out.


Watch some transmission noise videos and forget about it...

start up rattle could be a low oil situation, Check that and make sure your oil filter has a anti-drain valve.

Your startup 5 sec noise is prob lifters. I also have it. I check/change my oil regularly, I'm not worried. Now, if the tapping never goes away, I'm concerned.

The flywheel/clutch area is possibly the throwout bearing. Does the noise change when you depress the clutch pedal? If so, that's it. When was the clutch CHANGED last? Do you know? Could be close to your next...

Pilot bearing and throw out bearing are affected by the clutch position. A pilot bearing will go quiet when the clutch is pressed and the throw out will go loud when the pedal is depressed.

Alright, I am almost done with throwout bearing (It was shot) and I am in a situation. The way the bearing connects to the clutch fork is by two metal clips on the bearing, and if they seat partially wrong, they will make a ping sound and the bearing is no longer connected to the clutch fork, however the clutch fork also has a clip on it’s pivot point. When re-mating the trans and engine, I heard the ping sound. (For the second time, I had checked it a second time before bringing the two together) What I am trying to figure out is if the clutch fork pivot point clip was being re-adjusted, or if the bearing is no longer connected to the fork.
