My fab 2004 LS430 slowly looses air on the near side rear over about 4-5 days and an ex Toyota man suggests it could be this valve and possibly the metal pipe and it’s seals that link it to the air strut. Has anyone else have a suggestion. This valve is in very brittle shape but no air loss can be seen or heard. The next two images show normal ride height achieved in 30 -45 seconds of engine running.

Ray, 

 

can you remember how your oracle diagnosed this particular part? I have The exact same issue on my 2002, and would rather replace the valve if it was that part rather than drop £2k on oem struts if they aren’t gone yet.

Afternoon Ryan. I utilised an ex Lexus/Toyota man local to me and he had an idea that it would be this valve as he had never experienced the complete strut failure that appears to be the default Lexus position. Hope this helps 😁 Ray
