So I've begun the retrofitting of Ol' Blue to R134. New compressor, Volvo retrofit kit, etc. My question is: What is the black gooey material (elephant snot) covering the expansion valve? I assume that it is to insulate the valve and reduce condensation. Is it important to replace? If so where does one obtain this material (other than the circus)?
Thanks in advance,
RP
