I have a small (1/2” per day) leak coming from the front suspension. With EAS fuses pulled it drops evenly across the front end, the rear doesn’t drop at all. Rebuilt valve block, same result. Had read several places valve blocks can leak back into the system so I put in a new block. Again, still the same small drop. Eliminating the valve block as the problem I’m assuming this is downstream of them in the system. Have sprayed down air bags, top and bottom, and have not found any leaks. Anything else I need to look at? These are original bags so wondering if I just have pinhole leaks in them
