Hi all,

I will be repairing my valve block as the suspension behaves a bit weirdly from time to time and it sinks when sitting.

I was wondering which kit to get. I have found two kits:
- https://x8r.co.uk/range-rover-p38-e...l-liner-valve-block-o-ring-diaphragm-kit.html
- https://4x4airseals.com/product/air...id-o-ring-diaphragm-seal-air-dryer-repair-kit

The first one does bot have the desiccant for the dryer but seems to include two air compressor housing seals which the second kit with the desiccant doesn't have.

I will have a look if I need the desiccant but after 25 years it seems a good idea to replace it.. So my question is, do I need those two compressor housing seals or not?

This is for my '99 4l p38
 
I generally use X8R for EAS stuff. The two compressor seals are for the head & top plate. Whether you need them depends on how old & compressed they are.

I did try one compressor piston & cyliner kit from 4x4airseals, but it didn't seem to work as well as the X8R. Trouble is you cannot just based on one kit, because the end result varies with manufacturing tolerances. I have also had X8R kits where the cylinders were too tight on the piston seal.
 
On a slightly different but related note.

Does anyone know of anyone who offers a return service on the valve block? Ie either on an exchange basis or send yours in kind of thing?

The XBR kit for the valve block is good. Do not buy any EAS kit with orange O rings.
Personally, I change the whole dryer rather than mess about with desiccant, the dryer complete is not expensive. The dryer may be rusty inside.

It's so easy to do (even on kitchen table if you don't have a bench), that I can't see many people using a service that would be many times the price of the kit. There's also clear instructions on the X8R website, plus many videos on the interweb.

Thanks. I’m sure it isn’t that hard. Just a bit fiddly and I suspect not all that hard to get wrong. If I rebuilt it myself and it didn’t fix the problem. I’d not know if there was another issue or if it was a failed rebuild.

Although in reality, I’m not sure I’ve got the time and effort to rebuild it, too many other things needing my attention. Eg if the kit is £50. I’d happily pay another £50 for someone to use it and rebuild the valve block.
