Found the problem(s) Up line had leak at one of the mains and down line had small leak at the nose cylinder. Thanks to all
A couple of locking forceps, soapy water, a pressure gauge, and liquid Teflon are your friends...
I've gone through this pain a few times, I always test my air system - up and down - before closing everything up. If I lose more than 10 psi in 8 hours or so, I start chasing leaks. No plastic T's, wire wrap (not tie wraps) on airline/nipple joints, add thin lube to all air cylinders and excercise them a bit, and use liquid Teflon to seal all the screw-in air fittings before mounting the retracts and air cylinders...no leaks (knock wood) in the last 4-5 years since doing this.
