PAS rack leak / Rack rebuild

[malloryn]

Just had the MOT and failed on the steering rack leaking. The car is 4L 1996 chimaera.

This was a suprise as the last two MOTs passed with the leak and it hasn't got any worse. Only needed to top the PAS fluid up once.

Having cleaned up the rack the leak appears to be seeping from the top of the rack between the rack and the oval shaped plate. I assume that the seal here or some o-ring inside is leaking.

Has anyone rebuilt their own rack and if so where do you get the seal kits from?
Are any special tools required?

I've rebuilt brake calipers / cylinders before and assume the rack to be similar.

Does anyone know of any exploded diagrams for the rack?

Cheers

Neil

Not on the TVR but I had exactly the same problem with the neck seals on the XJS years ago. In that case I was able to buy a seal kit from the main agent and rebuild the pinion / neck assembly which has all the valving in it quite succesfully.
However I believe the TVR PAS rack is one of the few actual TVR manufactured components and that may mean that spares are pricey, tho it could have non-unique internals. Would be worth seeing if there is a repair kit available. As far as special tools, you really need to have a well stocked tool box for that sort of job, the least you'll probably need will include internal / external circlip pliers etc etc.
