R33 Gtst Box

[SirRacer]

I had my r33GTST box rebuilt last year with completely new bearings throughout and new syncros in second and third. It has probably done 1000 kms since then most of which has been casual sort of driving.

I took my car for a drive yesterday to try and tune my boost controller and now im getting a whine coming when i press the clutch in. Release bearing tends to ring a bell, however i thought this only made a noise when the car was in neutral or the gearbox not engaged. It doesnt make any other noises and the car drives fine.

I run 300kws behind it, however its only ever had the best oils etc.

On a side note, since it was rebuilt it has always crunched into second when the oil was cold. Is this normal considering my new syncros?

Thanks

Thrust bearing it is. It's a misconception that a worn thrust bearing makes a sound in neutral when the pedal is released; this is usually a gearbox related problem as with the pedal released, even in neutral, you have engaged the gearbox. In contrast, thrust bearing issues tend to show face when you push the pedal in because this is when the bearing is actually used.

Should have replaced clutch / thrust bearing when you reconditioned the gearbox...

Yeah i did, thats the funny thing. The whole car was put together from a shell using all new parts.

I also rung the gearbox builder who said it may be the scopgot bush in the crank. Any ideas???

Someone whos a mod or admin thought it was funny to put an auto change on the bush that goes in teh crank. Pretty lame really

It's not an autochange on the whole word "spigot" but it autochanges the word pig into cop.

Was the thrust race properly greased up when installed? It could be the spigot bush...

Hi Birds, thanks for your posts.

It was done by the engine reconditioner so in all honesty im not 100% but it didnt look too bad. How long do you think it is likely to take me and a friend (hes a mechanic but hasnt done one of these before) to remove gearbox (we have a hoist) remove release bearing and "spigot" and press in a new one?

You seem pretty onto it with these? Where did you get the knowledge from?

So basically its not a gearbox problem due to the gearbox not being engaged when the clutch is pushed in, and its likely to be one of these bits?
