Need conformation that it most likely is too much oil along with slugging liquid etc.
My knowledge is that while running it should settle to less than 3/8" to just above bottom of sight glass and be not more than 70 PSI above suction PSI.
This one is 85 PSI.
I have other factors to support the facts but am obligated to keep information non recognizable by the client.
This is second 100 ton rebuild this season.
