thanks for the advice. I’ll do the test tonight and go from there.Valve blocks keep the air in the struts. If your car doesn’t keep air when you disconnect the electrical and you just replaced your struts, then your valve blocks are leaking. I would just rebuild the compressor. Very easy and a lot cheaper. You do have to be patient and make sure you don’t break anything when disconnecting the hoses.
I went the other way and started with struts before the valve blocks and compressor and my suspension problems did not go away. It is cheap and easy to rebuild those 3. Good maintenance really.
If you know you have a good system for air delivery, then you can proceed with whichever strut that gives you problems. Starting with the struts, unless you can tell they are leaking, is the expensive way to go.
