When my 91, 1.5 civic is revved or ideling in neutral, especially when cold, there is a loose metallic rattling noise somewhere under the hood. This isn't quite as apparent when the engine has been running a while and disappears when the clutch is pushed in.

Also, no matter how warm the engine is there's a grinding noise when I accelerate & cruise along. It's a little worse in the first 3 gears. Like the rattling noise, the grinding noise disappears when pressing the clutch in, any ideas?

I'm thinking maybe bearings, or tranny trouble?

Thanks

Input shaft bearing in the tranny is most likely bad.

I agree with snowseeker, this bearing is cheap and easy to replace too. Although there is a chance it's your clutch release bearing, it's more than likely to be your input shaft.

I'm not much of a mechanic myself, would it be more cost effective
and feisable for me to put a tranmission from a 90 integra (engine type B18A) into my 1.5, and get someone to change the whole thing?

How much labour time would replacing the input shaft bearing take the average mechanic (roughly) ?

thanks

an integra tranny will not bolt up to a d series motor... ur gonna need a d series tranny, which are really cheap. if i were u id just buy a trans, put it in and call it a day

I am having the same problem, but i first tried replacing the clutch and throwout bearing but it wasnt it, the part is only 24 bucks, im gonna order it this weekend, the input shaft bearings are #16
