post a video. that would help immensely

 

an input shaft bearing noise goes away with the clutch disengaged (pedal applied)

 

I have a video but it doesnt do justice about the noise, Ill make another one on the weekend and uplaod it immediately.

Hmm well the noise happens whether or not the pedal is pressed.


As for the other question, the engine has been taken apart before

 

Taken apart before?..

hmm...

Try this: remove the inspection plate and check the flywheel for play.

(I'm thinking someone didn't torque the flywheel nut down enough.)

 

yeah just a heads up the car is a donor car that my uncle previously pieced together and gifted to me

( hes the super cool uncle of the family, everyones got one :P )

So im guessing something he put together wasnt properly tightened or something.

I went under the car and know for a fact the noise is coming from where the engine meets the trans. I will take a video sunday to post and confirm

 

That is a very good possibility. Someone who doesn't know these engines probably don't know that sucker needs to be tightened down a jillion ft. Lbs

 

Possibly the pilot bearing??? Since it still makes noise regardless if the clutch is pressed or not, and op says hes sure its at the engine to trans connection

 

yeah definitely where the engine/trans connection is. Ill get a video tomorrow. I once said i would never sign up for a weekend class, yet here i am 1pm on campus getting ready for a midterm

 

so here are the vids.

Vid 1: https://www.youtube.com/watch?v=j987...ature=youtu.be

this shows how prominent the noise can be in the cabin. its like a knocking/grumble noise



Vid 2: https://www.youtube.com/watch?v=PApe...ature=youtu.be

This shows under the car, where the oil pan is and where the engine meets trans. sorry its dark but if you look closely you can see it pulse and make the same niose as vid 1

 

as mentioned, pull the cover off and take a look in there. almost sounds like something rubbing on the flywheel

 

sorry for the late response! since the car is mainly a weekend car ill pull off that inspection plate and take a look.

What exactly am i looking for though?

just try to wiggle the flywheel around for play?

 

lightly pry the flywheel away. although i doubt it is the issue. as you would have severely rough clutch engagement. but run it with the cover off. poke around in there

 

Don't poke around in there with the car running though.

 

Ok thanks!

Quick update: i actually went ahead and changed the motor mounts. This solved the issue at idle when coming to a stop with the car fully warmed up.

However during cold start idle the noise is still present. I'll go ahead and start removing that inspection plate

 

Is your clutch fork loose and wiggly when it's released?

 

Hmm you know what, I haven't really checked that. I'll do it this weekend
