P38A Air ride suspension..... Again!!

Air ride suspension, on the way back from the hospital (always on the way back!!!!) anyway the back end has gone down this time, what valves to check for the back before I have a look tomorrow? the front is (it seems) to be going down over time, but I am guessing air is trying to level up or something like that

How old are the rear air bags? Maybe a tiny leak

Newish, arnott ones all 4 of them, im thinking EAS again

When I've had issues I usually follow Wammers EAS guide in the technical section which in the past has led me to a new compressor, valve block overhaul and 2 airbags

I will have a spray with soap and water 2morrow, just wants to know what ones to spray, save me soaking the whole block

I used this, there is a diagram showing which valve is for each wheel http://paulp38a.com/range-rover-p38/eas-valve-block-renew/

This is also a useful document https://www.landyzone.co.uk/attachments/eas-system-information-document-pdf.60384/

Thanks Tony

I rebuilt my block a few years ago, the last time it was a diaphragm, probably the same again I hope its easy, I have another block to use for spares

My guess would be the pump needs overhaul do the finger over the pipe test as in wammers guide

You will be past worrying the time you are not on the way back.

I'm here to tell you it could be anything. I'm in a new wing here on account of the anguish I'm suffering on my EAS overhaul. Only lockouts have a more intensive wing.
It's easy to kid yourself there's no leaks. I found a really strong solution of washing up liquid, which stuck longer, more revealing. Suspension up in the air (if it'll go).
I had my exhaust checked out by my friendly local exhaust man who explained that the airlines are routed in the same vicinity as the rear over-axle exhaust trombone.
If you've got a P38 it must be at least 15 years old. He explained that the airlines there over time go brittle and minute cracks appear. Where the lines show up over the rear chassis
arches , right over the subframe and down the other side are a peach for driving you daft. I ended up renewing all my airlines. Far worse in your mind's eye than in reality. This went part way
towards a remedy for my problem which at one time echo'd yours. I convinced myself there were no leaks mainly because I didn't want to see them. I completely overlooked the line to the compressed air receiver
through inexperience and ignorance. With the engine off the tank and its lines are isolated so, if the car doesn't drop over time you can be kidded there's no leaks. The line to it does a complete lap of the aforementioned route. The word on the street is the air tank is pretty well bomb proof. Yeh, right. Don't trust anything. Even if you're as paranoid as I it doesn't mean no one's after you, especially dratted camouflaged
air leaks. In reality you can renew/overhaul everything on the EAS system from ecu to the last o ring and collet for between £350-£400. If anyone is remotely less careless and ignorant than me there's
nothing challenging. The gospel according to St. Wammers needs to be printed out, put in plastic wallets and an oil proof wallet. Peter's top tips: when setting up and calibrating with your laptop on the the driver's seat, don't reach over to reset the height rocker. You'll touch the washer stalk and fill your right ear with screenwash (if the pump works). Don't lean on the door whilst observing happenings, you'll touch the door lock and
the sudden clunk'll give you a panic attack. Is it only from the hospital your rear end drops? My dog's rear end drops when we go past a vet. Regards. P.

Peter.... what drugs you on m8? when I get the air ride up again and get to the hospital, I'm going to ask for some!!

New pump in already, it works fine

We'll dang my hide. I've finished my overhaul, or so I thought. The pump was off more than it was on but I thought as this was a preventative/ preservative overhaul I might as well replace the compressed air receiver. Give me chance to check for pressure validity derust it, proof it, hammerite it, waxoyl it and send for the doctor. Damn me all over the place! This bombproof, extremely rarely leaking tank was as porous as a loofer. To state the obvious, I really never stood a chance of leak detection with it in place. I love this air suspension but it's like being in love with a woman well out of my league who can kick box as well. A bit like matron. To all who are suffering at the hands of the EAS, my heart goes out to you. Regards Peter.

I cant disagree with that logic at all

I sometimes feel like I've slipped into a parallel universe when I visit this forum...

I want my Mum.....

Is the exhaust sound? That can melt airlines if it leaks in the right place.

I cant look at it today, appointments, borrowed the wife's car, have to fix the shower tomorrow, and the stop cock is leaking as well, yea all gone t*ts up this week

Good for you but since you ask, among other things, I'm on cialopram, escitalopram oxate, fluoxetine, fluvoxamine, sertaline, desvenlafaxine, duloxetine, levomilacipran, WD40 and venlaxine. Matron gives us something with our cocoa to keep us moving, she says. I think it's domestos and gunpowder. I think you might need a prescription, though.
