Turbo Oil Feed Line Pressure Question / Sanity Check
I drilled and taped the fitting over my oil filter to run a -4 oil feed to my turbo. The engine has been run previously, but it's been more than a year and I was told I should prime the engine before firing it up. I removed the fuel pump fuse, removed the spark plugs, disconnected injectors, disconnected coils and hooked an oil pressure gauge to the turbo feed line. I have tried turning the motor over for about 10 seconds, but after 3 tries, I'm still not getting any signs of oil in the feed line.
Is the starter not turning over fast enough to prime the oil pump or do I have another issue? Any suggestions?

I built a large accusump type charged tank that held 3 quarts with a cut off valve and pressurized to 90 psi. It filled the front port above the filter because I never had luck priming them by the starter method.
Having said that, pulling the plugs will allow 300-350 rpms cranking and you might see pressure. I have no patience, so I skinned that cat another way

would it help to unhook the feed line and pour oil down it? thats what i was gonna do with mine, hold the turbo end up high and dribble oil into it till it was filled then screw it in.

I prim the motor befor it goes in the car. I just add 6 quarts and make sure its level and bump the starter with a battery and some custom made jumper cables. It takes me about 30 secaonds to see oil come out of the hole where the oil sending unit goes. Oh and 5 seconds on the starter each time.
