EAS allowable leakage rate...`

[Nomad9]

Hi Forumites,
I've recently purchased a 98 P38a from Melbourne, drove it back to Perth 13.8 litres / 100 klms. Great vehicle very impressed. When I bought the vehicle as mentioned in another post I had a slight problem with the solenoid valves, I got a replacement block from TRS, no complaints there. Blocks fitted and has made a significant difference, I'm now just wondering what's a reasonable leakdown rate? If you didn't drive the vehicle for a week and the suspension drops to say access level is this acceptable? Or would you expect the suspension to stay at level and not loose pressure indefinately, I think personally this is unreasonable but I'll wait and see what reponses I get.
Thanks to anybody who responds.

It shouldn't leak at all.

Hi Jon, Ok well that gives me something to work towards, out with the soapy water solution again I suspect.............. bugger..............

Provided my compressor is not running on close down, mine will stay at whatever setting it was parked at for up to 3 weeks (the longest I have left it !)
I know I have some valve block problems (the usual white powdery deposits) and my compressor is only about 50%. Nearly time for another air rebuild. This one has lasted over 100K of really hard work so it's not a major concern.

Correct, it shouldn't have any leaks but the system does self level every 6hrs. That means that if the car is not parked on a flat/even surface, it will eventually self level itself down to the bump stops.

As an example, park it with one wheel on a kerb & shut the door. You might hear a couple of solenoid movements. Open the door & shut it again & you'll hear a few more as it starts the levelling process. This is what happens every 6hrs (I think it's 6hrs).
