Unfortunately for me it was only after fitting the X8R "o" rings that I saw their hit and miss successes on the web.
I've had an air leak for a while, mainly when it was cold outside.
I have isolators from the output side of the vale block for the air bags so knew it was the block, which on stripping found the diaphragm damaged.
The car now fills a lot quicker but I have found leaks on virtually all of the top solenoids with soapy water and the car drops in a few hours
I stripped some of the worse leaking solenoids to see if I had caught/twisted any on the seals but they are all fine.
I have now sent for a set from 4X4airseals who were originally Landyair, has any one had any issues with their kits ?
