Clutch problems

Does anyone have any clue why this is happening
My clutch is sticking and especially when the engine is of
Alfa Romeo Spider 916 by 3.0 2002
Clutch has been converted to a solid flywheel and clutch
Apparently the rod has been lengthen a tad as per the mechanics experience (see short video) it didn't engage enough
Now the clutch pedal stick when pushed to the floor sometimes and I have inspected the master and the slave no leaks

There's no video - what do you mean by the rod? The part of the slave cylinder which pushes out? I'm not sure why your mechanic has done this, there is no need, a slave cylinder from 156 V6 is the easy answer.

If the clutch is not returning it could be that there is something preventing the fluid from flowing back out of the slave to the master cylinder. Maybe a master cylinder fault, maybe the flexi pipe was clamped and it has kinked in, could be a problem with the 'valve', in the clutch line, could be letting air in somewhere. Does the clutch sometimes work OK and sometimes not? Or is it sticking all the time?

Could it be the damper? I thought there had been a number of cases of this problem in the past that was found to be caused by it. Believe several people have deleted it without problem. I think this would be a direct replacement. At that price well worth trying. I would check the unions are the correct size first though.

I have heard of a replacement but didn't know from where so thanks for your post
I heard that alot of people have taken them of without problems but it's worth a try
What does the damper actually do?

Basically it is supposed to stop the following.

"......imbalances in the crankshaft of the vehicle engine or engine firing impulses are transmitted to the flywheel which undergoes a swashing movement, the flywheel swashing movement in turn leads to vibrations of the spring fingers of the clutch release mechanism, the vibrations of the spring fingers are transferred to the release bearing of the clutch, and the vibrations propagate backwardly through the hydraulic fluid in the slave cylinder, through the hydraulic fluid in the conduit interconnecting the slave cylinder and the master cylinder, through the hydraulic fluid in the master cylinder, and thence through the master cylinder push rod to the clutch pedal where they are experienced by the operator as vibrations of the clutch pedal. The propagated vibrations also generate a pedal growl which is audible to the operator as well as a clutch roar which may also be audible to the operator."

I suspect the problem is that the over time the membrane splits and the hydraulic fluid gets into the void behind. The membrane may then get pulled against the inlet or outlet of the damper either a) making the clutch pedal very heavy by restricting the flow to the slave cylinder or b) restricting the return of fluid to the master cylinder and then to the resevoir which would result in little resistance at the pedal on depression.

It is only my theory and I haven't had this particular problem but I am expecting I might. Also I am not sure that the Land Rover/Range Rover damper is identical but it also seems to be the same part number as used on the MG TF so it wouldn't surprise me if it would work or even be identical to the one on the GTV. NB the GTV installation is connected into the clutch circuit with 1/4" brake pipe, as is the Land Rover Defender I believe.

Take a look here for the actual patent!

Clutch sorted now
A new master and slave cylinder did the trick
