Default No oil to turbos

I was checking to make sure my turbos were getting oil and they aren't .i have the oil pan adapter for twins. There is no sign of any oil whatso ever which has me worried . Swapped a 2000 4.8 that was running into my nova . I broke the sending unit pulling the engine and haven't got another yet. Is it possible the oil diverter barbell is letting that much oil by ? I doubt it but I'm not sure . I'm going to get. Mechanical gauge and make sure the engine is seeing oil pressure . I hope I haven't screwed it yo because I've had it running . Any help is appreciated thanks.

Ball bearing turbos? They have very tiny restrictor plates to make sure only a dribble gets to them. They're not pressurized like the engine - the oil is just for lubrication. You really need to be sure you're seeing no oil - as in absolutely nothing is coming out of the drain side.

Journal bearing turbos . The feed lines have no traces of oil nor do the returns .

Does the engine have oil pressure at all?

I took the plugs out and turned the motor to prime the pump . Oil is coming out . I just would think there would be residue of some sort . I'm going to leave the drain open and hook it up again to see if it's flowing through them. I don't have an oil pressure gauge hooked up yet . Obviously I need to do that.
