could be residue from installing the dye. the valves are not replaceable. the entire line needs to be replaced.
look hard at the condenser. it is a common failure.

the cap was on when put dye in. is that posible.

yes i put dye in low side.havent got to the condenser was high side that had dye. ill replace that line

which port?? you must install the dye on the low side. are you referring to the high side?? If you are, then the line would have to be replaced as it is a ball.
