This isnt a problem or anything (or it could be not sure...) but I notice in the morning or when ever I start my car cold, with each time I press on the clutch (disengage) and then I let it off (engaged), I would drop around 100 rpm. And it would keep dropping 100 each time I let my foot off the clutch. Im not in gear or anything Id just be warming my car up.

Does this happen to anyone? Im not bothered by it. Just kinda interesting to see....

 

hmmm.....while ur in neutral? ....ill go test mine out right now for u and let u know, my car is cold right now as well....i know there's a slight sound change when u press or depress the clutch but thats normal...never noticed my rpms tho


BRB!!! haha

 

yeaah! thanks man lol. but what made me notice the RPM drop was BECAUSE of the sound change. It would change too with each engagement....

 

i don't think it has to do anything with the clutch, i just started mine up...then it drop exactly 100rpm, then dropped another 100rpm again...maybe u noticed it coincidentally??? ( i was pressing my clutch in over and over...nothing) unless u have a another issue...

but if you really think about it, if ur in neutral the transmission should not affect the rpms at all...well cuz its nutral...i believe you just noticed it as a coincident

 

the sound change is normal, its the um um um damn, i have a brain fart, i forgot the name of the bearing. Thats why its recommended not to hold ur clutch pressed in at stop lights because its extra pressure on the synchros and that bearing wears out faster over time

 

Yeaah I know which one you mean. I believe its the throw out bearing. If not its the thrust bearing. One of those. Should of took notes in transmissions class!!

Since its 8:36pm on a lonely monday night I went out and recorded a video. Im uploading it right now it should be around less than 10 mins!!

 

Here it is! OH and I lied lol I guess it just drops around 20 to 50 rpm with each clutch engagement.

Turn up the volume. You will hear the small "clunk" sound and thats when I engage my clutch and release the pedal. I started my car twice in this video.

holy **** haha!

im studying right now for tomorrows test that i have, when im ganna take a break ill go check it out again

where is ur noise coming from? pedal? clutch master cylinder? tranny? pin point the area if u can

 

just went out again, my rpm's dont pulsate like that with the clutch movement. just the normal rpm fall after start up...hmm i think ur situation is odd, maybe some other 6speed owners will chime in

 

Yeah its pretty weird. The car drives perfectly fine its just weird how it does that when I start her cold in neutral.

 

Well you do disengage the clutch disk, and input shaft of the trans when you press it in...as well as put load on the throw-out bearing.

 

Have you ever changed the gear fluid up to the 93000?

 

I dont know when the ex owner of my car changed the trans oil. I need to go check but I dont think that would be cause of the problem. Theres no fluid in the bell housing where all the movement is happening since Im only in neutral.

this kinda seems more mysterious when I think about it haha. maybe our master cylinders put load on our engines everytime we move our clutch

 

you not the only one, happens to me too, i dont think its bad but I can never figure out why..,..
