I suppose the worst is it will clog up with dust from the dryer. In theory there shouldn't be any dust but every valve block I've taken apart has had white dust in it from the desiccant.
I have new desiccant to put in mine this morning.
All assembled, all working but.......
Testing with soapy water, there are some bubbles appearing from the base of Left Rear valve and strangely from where the wires exit from third and fourth from rear!
All double checked but as said previously, I have lightly smeared the thin spindle O rings.
What a pain and where to from here? Is it the quality of the O rings?
I noticed that only one of the valves has the "square" O ring on the base, I assume that is correct?
What O ring kit did you get? It does sound like they could be iffy.
Just spoke to my local indy Land Rover guy. His experience with fitting seals is it can be a bit hit and miss with the quality of seals! He would rather fit a good used secondhand valve block rather than trust a set of seals! Not what I want to hear.
Never heard of them, I always use the X8R seals, https://www.ebay.co.uk/itm/RANGE-ROVER-P38-EAS-AIR-SUSPENSION-VALVE-BLOCK-O-RING-DIAPHRAGM-REPAIR-FIX-KIT/321451232414
Hmm. Spoke to a couple of indys,quality can be iffy.
Waiting to hear from Land Rover tomorrow. Apparently they do a valve block repair Kit. They are checking availability and content.

More than likely can't be arsed lol.
Anyhow, I don't know where he'd get a good used one from as most are likely to be 18 years old or more.
Problem is when they are charging by the hour, it'll probably cost more in labour to do a rebuild properly than the cost of a secondhand valve block. It isn't the usual mechanic type work either, it doesn't involve big sockets and breaker bars.
The seal kit turned up at Harwoods. Bit of a laugh, £88 buys you for our rings, a guy friend and f The seal kit turned up at Harwoods. Bit of a laugh, £88 buys you four O rings, a diaphragm and 4 cap bolts!
Wowser
I did have a look on microcat but didn't look up prices. Glad I didn't
I’ve given it a lot of thought and have ordered another set of seals as recommended by David. I’m away for the week at the moment but on my return I will strip down the valve block and renew all the seals again with fingers firmly crossed! If the seals are good then all should be fine............
All seals renewed again this afternoon.
Got sometime free tomorrow so will be fitting it and fingers crossed.
Just to finish off. I rebuilt the valve block the second time with the seals recommended by David above. The first set I had for one reason or another it seems were letting by at the very thin 1 mm O-rings around the spindles of the solenoid's.
I fitted the valve block about six hours ago and the car is still sitting level where it should be. Let's see if it's still there in the morning and then I will put a bottle in the fridge to celebrate!
Hopefully……….Happy days and thanks for everyone's advice. !
It’s a few days later and the car is still up on all fours!
