My blob refuses to select any gears when the engine is running

I'm pretty sure this is a clutch slave or master cylinder fault, I just don't know which one.

Gears are all selectable when engine is off by the way.

Where the pin on the slave cylinder goes into the clutch fork I can push that pin in easily with my hand which makes me think its knackered and not pushing the fork when I depress the clutch.

Could it be the master cylinder causing this though?

Get someone to operate the clutch while you watch the slave

bleeding the clutch is awkward, u have to take bolts out and but the nipple to vertical. sounds like the slave is buggered but try bleeding it

Ok I will bleed the clutch tomorrow, has it been known to happen that a airlock just appears in the system?

I will see if i can borrow a neighbor tomorrow R1c

Bleeding didn't change anything

I'm still not sure whether its the slave or master gone though?

Is the slave operating when the clutch pedal is pressed?.

Yes the pushrod does move back out when the clutch its pressed.

I've had a think and I'm pretty sure from what I've seen before the only way the slave can fail is if its physically leaking and it can only leak externally through the push rod seal.. correct?

Therefore as I have no leaks, its must the the master.

I believe the master can leak internally, I'm ruling out any clutch problems as yesterday when trying to figure this out the clutch stayed to the floor upon testing, so there is obviously some pressure issue here.

The pedal needs to be pumped to return pressure for the clutch pedal.
