i have a 91 civic si with a d15b and an si cable trans. i swapped this motor in last feb (almost a year ago) and installed a new exedy clutch kit as well. ive noticed within the past few days that i have quite a noise when the clutch is released, kinda squeals when i take off in first gear. theres also a sort of whining noise when i release the pedal (isnt a noisy pedal arm) and it goes away when the clutch is pressed. could this be the input shaft bearing and not the release bearing? i can change a throwout bearing without much problem but cracking into the trans casing is another story

 

That's your input shaft bearing man. I know, it sucks, but it's common on these transmissions.

 

how long do you think i have before the trans effs up internally?

 

^ive been driving mine with a noisy isb for 9+ months straight now and it still drives like a champ...then again i don't drive like an idiot and i have yet to hit redline with my new motor

 

yeah im not driving this si all nutty either. its my daily that i drive to work and such. it shifts and drives fine so far just that noise when driving or idling.

 

Some take forever and some go rather quickly. Eventually the bearing will fall apart and could potentially eff **** up.

 

What about the throwout bearing. What is the danger of that failing?

 

It will probably chew up the pressure plate since it will no longer spin with it.

 

got my dx hatch done with its swapped b7. had to pull the b16 i juss put in over the summer cause i wasnt passing emissions with that motor. so looks like i have the dx to drive while i pull this si trans out. def not gonna drive my car very far until its fixed
