Thread: EAS Leak Test

How annoying! Not sure about the nature or worth of a leak detector gas
... a liquid leak detector is probably the best bet...one which gives decent bubbles. Different concentrations of detergent can be effective. Also if it's slopped on with a paintbrush then the initial sudsing is minimised making it easier to detect leaks... (learned this after lots of practice!)

Are you sure it's the valve block and not connectors to, or splits in the airbags?

Thanks for the painting on advice.

If the problem lies beneath the valve block - any suggestions on how to get the soapy solution there? And see it - mirror I guess? It would be ideal if you could fill the EAS box with soapy water - but that's probably not recommended.

Been doing some bubble research - 3 parts water, 1 part detergent, 1/2 part white corn syrup (Woolies/Coles I assume) and some food colouring. I'll try that. It'd be ideal if it was flourescent flood colouring.

I just want to be more scientific - rather than just keep taking the block out, taking it apart, putting it back and hoping for the best.

Therefore, I'm going to put a condom over the exhaust silencer - see if it fills overnight (with air that is).

And I'm going to blank off the tee connections to the valve block - to see if the car stays at the same height without the valve block - just using the manual inflation system.

Any other suggestions would be aprpeciated.

Should clear up a couple of misconceptions...about theories as to EAS leaks that is

If you pull your EAS relay over night does it still sag?

Yeah. It still sags with the eas delay timer inactive. Doesn't that s signify a definite leak rather than the eas brain working overtime once the engine is off?

Sean give this a try:
remove valve block assembly from EAS Box.
Re-Install Valve Block & connect all airlines without box in vehicle.
This way you can apply detergent allover and run in vehicle and you are also able to tilt valveblock to see underneath to check for any leaks there.
I did this with mine & found one of the solenoids causing my issue. Sure enough once pulled down it was that fine oring on shaft ( again).
Hope this helps! good luck.

Just back from woollies mixing my special new leak detection concoction. Will try reinstalling without the box. Good idea.

Yes,
Personally I wouldnt be introducing liquid INTO the EAS system, pipe work.
Not sure how old your air bags are, but check for cracks and leaks at different height settings as well.
