1996 HSE 180k kms (115k miles).

New airbags and o rings
Valve block o rings replace
Compressor rebuild done

Since doing the valve block I have problems with the system emptying the tank whenever it feels like it. Sometimes you can hear, and feel, it exhausting completely as soon as you stop! But mostly it just leaks down when you stop, some times after only 10 minutes sometimes its fine for hours.

I tried the "EAS Wake Up Off" rewiring, but it has the annoying issue of holding everything fine for as long as you want, but then when I turn on the ignition it drops to access mode. Kind of defeats the purpose.

I think I've either still got a leak somewhere in the valve block, (which I can't find while its still all connected) or the driver box is faulty.

Any suggestions? Is there a way to confirm a faulty driver box?

Does it stay up overnight with the EAS relay pulled?

 

[ytt105]

Yes

I just went out to it after it had sat all night.
Everything was fine.
Fully up, no need for pumping.

Went 5 mins down the road, pulled up for gas, when I restarted it was down and had to pump up.
When I got home, fully pumped by now, I turned it off, left the door open and it started to exhaust all the air.
It will be empty now!
This can't be good for my pump!

Instead of buying a new one 350.00 you could get a used one and confirm your suspicion...

First thought would be to recheck what you did last. If it worked before the valve block rebuild and doesn't work right after the rebuild I would go back thru the rebuild before chasing something else.

ding ding! Terry gets the prize on this one! It sounds like something went not quite right with the rebuild, suspects are the Non-return valves, ensure they're oriented correctly and make sure you put the valves back where they belong. 4.0 first, then 2.5, then the two 2.0 and the other two 2.0 directly below them.

Dennis, you lost me with the 4.0, 2.5....

These are the instructions I'm following

Congratulation to Terry Y and Shupack

It was one of the small o rings on one of the non-return valves.
It was broken.
Fitted a new one and no it all seems to be good.

Thanks guys, saved me hundreds!
