Oil in the TEV equalizer port
It ocurred again today. It seems that mostly having condemned a TEV, that upon removal of the valve from the system, that often the external equalizer port of the valve is oil logged.
Is this observation a CAUSE of malfunction, or a SYMPTOM of the malfunctioning or misapplied component? .:confused:
I've conditioned myself to the point that when I open the equalizer connection and oil squirts all over me, that I am confident that my diagnosis is on the mark. And vice versa, the absence of oil in the TEV eq. port (might) cause me to further evaluate a system, aside from any concerns regarding TEV operation
