Time to replace my EAS valve block.

I have done the seal kit on the valve block, but still it let's me down!
Airsprings replaced
Air pipes replaced

I disconnected the 4 pipes from the valve block and fitted tyre valves to each, filled with air to get me home towing a large twin axle caravan after the rear end kept going down (both sides). The pump finally gave up too. I used a compressor to pump up each corner and they all stayed inflated for the 270 mile drive home. Clealy, this rules out leaks in the pipes and air springs which are new anyway.

I need a valve block it seems.

Can anyone point me in the direction of one a t the right price?
 
If the compressor has given out it's because it's been running to feed a leak. If your air bags are staying up from the valve put in the line, that precludes the airbags and the lines. have you checked the tank ? The valve block is essentially a couple of big pieces of metal.. the weal points there would be the seals and the diaphram. maybe you pinched an o ring or something wasnt sealing ?
 
Hello I had the same problem, I put silicon on all the seals and have not had a problem since.hope this helps
 
UPDATE:
It seems that my valve block is not at fault, having looped out the block and things seeming to be OK, I left the vehicle for a couple of days and the front o/s corner went down!
The fault lies with the T-pieces that were supplied with the emergency inflation kit that I had fitted - would you believe it. The kit consists of 4 tyre valves connected into each of the airlines that feed the airbags, this is done by cutting each of the air bag pipes and inserting a T-piece then connecting in the valves one by one. There was a very slow and almost un-noticeable leak on one of them. They are plastic in construction and I think that the heat under the bonnet has in time affected them. I disconnected the system and replaced the T-pieces with straight through connectors thus returning the system to normal. Unfortunately, I only had plastic straight through connectors but have ordered some metal ones that should arrive in the next couple of days. I picked up a new compressor from Emmotts of Colne and everything seems to be OK. As soon as the metal connectors arrive, I'll get them on. Have also ordered some Schrader valves to keep in the vehicle that I can connect in the event of a failure in future, rather than being permanently installed.
A lesson learned.
 
Yes, don't put anything on there except original stuff. If you need the emergency inflator it is easy enough to plug them in. The kits on eBay etc are utter crap. There was one fitted to mine when I got it and it was leaking like you wouldn't believe. I got decent stuff cheap as chips from Activ-Air, they make stuff for the airline industry and trucks so decent stuff.

Metal connectors not required on the P38. It isn't like there is 30 tons of weight on it. Activ-Air know their stuff and were very helpful when I wandered in. Gave me a load of scraps for free and really knowledgeable.

Haven't you got enough places to leak without adding to them ?
