Hello all.
So after replacing all 4 Airsprings with new Dunlops and rebuilding my valve block I have some leaks. I made sure I put the NRV back in properly and did not lube them. I actually did not lube any of the o rings. However My rear springs now lose air to the bump stops in a bout an hour. The compressor ran all the time and got super hot. So I pulled the EAS valve block to dive back in for round 2. I have read through RAVE and it appears that NRV 2,3 handle the airflow to the front and rear and I think it is not sealing well. When I had the block apart I noticed that the valves themselves had shiny metal I assume came from the galling of the ALuminum on the block itself. there seemed to be a few sharp edges. I plan on taking the new o rings off the NRVs and carefully filing down the rough spots. My fear is altering the shape of the cone so that even when the new o ring is put back on it will not seal. Can you buy new NRV cones? anybody know where? or have a part number. I have searched on LR direct without much luck. I also remember that the plunger O ring on the shaft of the solinoids seemed to have a touch of lube on them. Should I lightly relube my new solenoid plunger o rings? Those also could be my leak. All my o rings on the valve box to the air spring airlines, drier,and tank are super tight to remove and pass the soapy water test. No bubbles anywhere. The other though I had was my ride height sensors are old 130,000 miles on the truck and could be faulty and telling the ECU and the valves in turn to lower the truck. I will have to listen and observe for clicking of the solinoids when I get out. I might replace all 4 ride height sensors while I'm rebuilding the system.
Any information would be helpful especially those who have rebuilt EAS valve blocks
