Rb25det Gearbox Problem's!!

[Nismo_Boy]

Hey guys,

My rb25det gearbox is making a weird noise, only in 1st gear just as you release the clutch. It’s not grinding the gear, or grinding going in. It’s more like a dry bearing noise, but it will only happen as you release the clutch, and only in 1st gear.

We had the same problem with my fathers Porsche, and the throw our bearing ended up literally exploding inside. Could I have the same issue? (my throw out bearing isn't really noisy, it has just started to make a very faint sound though)

I’m running an OS twin plate which needs to be replaced due to it slipping, but wont have the new clutch for another 3 weeks. The problem only started 3 or 4 days ago, could the fact the twin plate is stuffed course this kind of weird noise?

maybe redline oil might help??

Thanks guys,

Couldn’t wait for my new tricky twin plate to get here, so went out and bought a new single plate already here and a throw out bearing. Seemed to do the trick. No more weird noise!
