P38 EAS Problems after rebuild

[LukeP38]

Hi All, I'm a newbie to this forum, thanks for having me - a wealth of info.

Any suggestions? I've recently overhauled my EAS. Bags in January, Compressor two weeks ago and Valve block this week. After the bags and compressor the system was operating normally.


However, after overhauling the valve block in "standard" profile the car sits like the left side is high profile and the right is access.... Using the EAS unlock software I can go to the heights tab and level the car up with no leaks, so the valve block appears to be working ok.

i have tried every combination of resetting heights, overcompensating heights for the "low" side with no luck. any suggestions or experts who'd have time to take a 5 minute phone call?

thanks in advance
Luke

G'day mate, welcome!

Your post would be better off in the P38 section of this forum (I'm sure mods will move it).

One thing I can suggest is that you check the air lines for each bag are in the correct place on the valve block. Otherwise, I'll hand it over to the other guys!

Cheers
Keithy

Check and double check the valve block for leaks. Are you positive you've put the solenoids back in the correct position? Through experience, I've learnt that you have to be meticulous with a valve block rebuild.

And some... relatively anal would be only just good enough. FIND SOMEONE WITH OCD FOR THAT JOB.

I know its a pain in the ass but I would be pulling the valve body apart again & double check everything. I've found o rings out of place on reassemble . Even though I have been extra careful the first time around . Doesn't take much to upset things. Also make sure everything is where its meant to be

Those pesky 10 x 1mm O rings are the cause of most of the woes after a rebuild. Check with a magnifying glass and perfect the twist and push reassembly method.

+1 on those o rings...rebuilt mine and was absolutely, 100%, no ifs or buts sure that it was good........pulled apart and nipped o ring....has been good for 2 years.

Where are the 10 x 1mm O rings situated?
I'm trying to find a leak on mine with no luck, so a valve block inspection it is in the near future for me.

They're the ones at the base of the solenoid stems as shown in the attached - they pinch all too easy:

I pulled my valve block out this afternoon to do a rebuild.

The system of using collets to hold the air lines is an absolute pain in the proverbial. It's all to easy to score an air line whilst pushing in the collet and pulling out the air line.

I got a tubing cutter which does a great job. They are in the irrigation section at bunnings

Holman Universal Poly Pipe Cutter I/N 3120192 | Bunnings Warehouse (http://www.bunnings.com.au/holman-universal-poly-pipe-cutter-_p3120192)

It helps to have a nice straight square edge on the tubing

Yep, got one of those.

[davidsonsm]

Pencil sharpener is also a prerequisite to ownership. To chamfer the edges after cutting.

[daf11e]

As Ron said damage always seems to occurr and yes chamfers etc are good but eventually you run out of line.......especially when you are continually pulling out checking leaks etc.....eventually had to change line but touch wood been good for a couple of years..........probably should keep quiet.
