Hi Steve, Did you find anything in your valve block that may have been the issue, eg broken squashed twisted o rings??

Hi Peter,
Nothing appeared to be damaged, though I am pretty certain it had never been taken apart before, so all the rubber bits were about 14 years old and some were pretty hard.
The block itself was very clean.
Since i did this the EAS is behaving much better

Wonky the Range Rover
Just completed replacing all the O rings in the valve block and in the failing light of Sunday night, put the whole EAS unit back together again.
Imagine my disappointment when the EAS didn't fire up, so back to the manual valves and I pumped the bags up.
Next morning the NSF was on the bump stops and the Wonky Rover was born - most frustrating and responsible for my apparent lack of humour.
Fortunately I got back home early on Monday in the Wonky Rover (looking like a drunk jacked up not-so-hot rod) and in the daylight whipped off the valve cover for the NSF (number 4 from memory). It gave a off a small 'pop'even after letting out all the air.
I then pumped a little more air into the line and sprayed some washing liquid mix over the exposed valve and noticed air bubbling through the shaft. These have the tiniest o rings fitted.
I removed the valve from the block and there, unnoticed during refit, was a speck of crud that was stopping the o ring from seating properly, how it got there I don't not know as I swear (and swear I did) that it was all clinically clean.
Cleaned off crud, put back together and reseated valve, added air, washing liquid test, dried off block and all is good. Replaced valve cover and....
....it works!
EAS cranks over and is now working like a dream, you could say I'm floating on air
I'd got the new O rings from Rover Renovations eons ago and just did not have the time to fit them due to massive home renovations: The old O rings were definitely past their prime.
Not a difficult job, but definitely a bit fiddly
Big thanks to Paul P38's excellent instructions, I would have been somewhat lost without it

Bad luck about that bit of crud
I used compressed air and blew out every gallery i could see, then as per Pauls suggestion, I used cotton buds in the airline collet holes.
The EAS on "The Toy" as SWMBO has named my Rangie, is now behaving very well
I agree it's a fairly easy but fiddly job.
Next step for me is to finish off my bypass setup and put some spacers under the EAS box to lift it off the body.
