Just overhauled eas valve block now no lifty

Hi All,

Car had been settling a bit at the front overnight but otherwise ok.

Always shot up in the morning, so to speak.

Overhauled a spare valve block - -all new o rings, diaphragm ok.

New driver pack.

Now it won't lift at all. Pipes in nicely and no leaks visible.

Some clicking from the block.

Any pointers please? Haver I stuffed an o ring somewhere?

Where to look first?

Cheers.

Have you got any air pressure?

are the non return valves in the right way?

Thanks --


I assume there is pressure, but its a good question - how can I check?

Non return valves would be the first thing to check, I think.

Back on to it tomorrow ...... the previous block wasn't that bad, I guess I could open it and check it over.

Cheers.

If you have had the valve block out all the air will have gone. Has the compressor run?

Yes. I let run for a good 10. Minutes with a door open and no movement at all. Compressor didn't stop running.....

Right - if the nrvs are in the wrong way the air will escape from the exhaust, won't it?

You then may want to consider where the air is going if it is making good pressure. Think you may want to open the valve block and have a look what you have done wrong. EAS Valve Block Rebuild Guide | PaulP38A.com

if you give up on it , then i will but it off you as want to air my 71..

I have a brand new valve block for a 93my classic, it's the one that requires the driver pack to be fitted, not the one that had the driver hard wired in

Sorry all, it's a 2000 P38 V8 .... not a classic!

Anyway, thanks for all the help - I've owned these cars for years and done lots of eas work but it can still humble me into jelly when a fault like this happens.

I followed Paul P38's guide slavishly (or, so I thought!).

I'm going to check the exhaust first to see if the air is passing straight through, then dismantle the last known good valve block so I can see the nrvs.

Happy days.

I'll be back later!

Cheers.

It's a P38 ..

I have a p38a valve block as well lol , good luck with the repair mate
