Hi All,

I have completed my G16B conversion and now I’m trouble shooting a few things..

Firstly I have 2 noises coming from around the gearbox.

First Noise is only there when I depress the clutch pedal so I assume this is the clutch release bearing. It is like a dry spinning rattly sound. Is it possible to get the bearing on its own? I couldn’t find any on ebay.

Second Noise is a constant high pitched whirring sound. The pitch increases as the revs increase but the sound is always there. I was thinking this is gearbox oil low, Spigot bearing or gearbox bearings.

Am I on the right path? Would like to know before I pull the box 

Cheers,
Aaron

Spigot bearings will not make noise when the clutch is released, gearbox bearings will not make noise with the clutch depressed and the vehicle stationary.

This noise happens when I'm driving in all five gears. It stops when I press the clutch.. Well I think it stops or the thrust bearing is louder

try this . put the transfer in neutral so the car wont move while in gear . run through the gears and listen carefully . if the noise is slightly less noticable in 4th gear than the other gears then it is the front lay shaft bearing , if the noise stays pretty consistent through all gears then its the input shaft bearing . either way both require the box to be pulled apart and bearings to be replaced so might as well replace all ball roller bearings while you are in there.
