Need Help!! How to Prime Turbo!
So I just finished the install of my new FP Red Turbo, JMF 02 Dump, Ported/Coated Exhaust Manifold. I drain the oil and coolant from the car to remove everything. My question is....well is there a certain startup procedure for a journal bearing turbo. I was told there is a way to prime it. I was going to search but obviously everyone knows that it's disabled at the moment. Any help would be greatly appreciated.
Right now everything is bolted back onto the car and all the oil and coolant has been filled already.

now I've got more problems. I have a leak on my oil supply line coming from the head. It's a flared fitting so I'm pretty sure there's no gasket or o-ring with these type of fittings so I don't know what the deal it. It's tight. I don't know what the torque spec is for these but I know it's tight enough to hold the oil pressure. I'm at a loss. By the way this is the Oil Supply Line/Filter from Forced Performance for Journal Bearing Turbos. My luck just sucks.

The oil feed line should have a copper crush washer on the head side, as well as the turbo side. If I remember correctly, there should be two washers on each end. One in between the bolt and the line, and one in between the line and the head. Same goes for the turbo end of the oil line.

^^he said its a flared fitting. I assume that indicates AN style flare. If the threaded portion going into the head is not leaking....check the flares for cracks or tighten it more. Normally I do snug..then another flat. Torque values on AN fittings are kinda worthless IMO.

oh....and for priming...why disconnect the fuel pump? Wouldnt it be easier to unplug the coils and crank? I wouldnt worry about coolant. If you are going to remove the line from the head...you could always just pour some oil into the line going to the turbo....of course it will just drain back into the pan. But cranking it will suffice. Mine sat for 2.5 years before I reinstalled it. To prime the whole engine I just disconnected the coils and cranked away.

well I put a very small amount of RTV on the threads. I know AN fittings are a compression fitting that doesn't require any type of gasket but I decided to try it anyway. I'm going out for a spin now to see what happens. I post the pics of what I'm talking about when I get back.
