Hey guys I really did try to find my issue with the search button, 1856 post came up. I learned a lot but not what I was looking for.I have no leaks at the bags, or the lines going in to the bags, ( thanks Dennis ) no leaks at the tank, no leaks at the lines going in to the EAS box. no leaks at the dessicate deal thing, no leaks at the tank gauge. So 5.5 hours ago I raised the Rangi to extended hight, rear wheels, from ground to fender arch was 35.5 inches. Front wheels, ground to fender arch was 35 inches. now I am at 35 in the rear and 25 in the front, now I get that the return valve is leaking by, but my question is why did my tank psi go from 80psi to 40? Could the air be exhausting out from the EAS ? :?

Sounds like a valve block rebuild in in your future.

I can do that, I have a spare, and I purchased an o-ring kit from Dennis at Rover Renovations. I thought that the EAS unit was self contained so when the bags and o-rings were all good externally the car would hold air regardless of what was going on in the block. So is it possible that the air is leaking by and going out of the exhaust. Can I install a check valve in the tank line after the guage, so I don't emptie the tank and wear out the compressor.

It'll take you longer to install the check valve than it will to rebuild the block. :wink:

I rebuilt the valve block on the kitchen table Scott, takes @1/2 hr the first time round. Just be sure to get the o rings perfectly flat with no kinks etc.
If I was out there I would do it with pleasure, but I am stuck in Va/Md right now :crybaby2:

Thanks guys, I have the EAS box on my coffee table as we speak. :shock: I also installed my valves to the lines and pumped the rears to 33 inches and the fronts to 31 inches. Thought I would just wait and see if there are any leaks at the bags that I can't see.

well I Rebuilt the valve block and now I have the compressor running all the time and pumping air in to the front bags. So there at the extended hight, even though I have it set on standard hight. Tank psi is at 125
I was so carefull in the rebuild not sure where i went wrong. :( Any help would be great.

Pull the block and check all o rings Scott.
I had issues the first time too, turns out I had an o ring kinked a little.

If you don't have a leak it shouldn't.

THe first block I rebuilt I had an ever so slight twist in one of the orings. Drove me up the wall!

Full tank and at correct height compressor shouldn't run.
I drove myself nuts for 1/2 a day looking for issues, then saw the kinked o ring when I pulled the valve block apart.

Well I put my back up block in and i'm currently testing it. I don't know the status of the block or the driver I just took off my buddys shelf. It appears to be working ok, but the compressor continues to run so I might have a leak at the collets not seeing any bubbles though. :roll: :roll:

unfortunately I'm still on night-shift at the "day" job...

check the non-return valves first, and the solenoid placement, something went back together wrong.

with everythign right, the compressor should run every 5 minutes or so...

My tank guage was at 130 psi an hour later it's at 120 psi what should it be? Where is the air going, I know the line goes in to the block but if car is not running shouldn't the air just hold. please remember this is my back up valve block. So would the air be leaking by and if thats the case, leaking by what? The diaphram? Whats the green thing, is that a preasure relief valve. :?
