New mk3 trying to learn a bit

Looking at your pictures and reading that an IC pipe boot came off, you have numerous entry points for dirt, into your engine.
You may very well have a dusted engine which will account for the loss of engine oil pressure.
A turbo in good condition will not leak oil past the seals. The stock PCV system for the 7MGTE, routes the vented gas into the intake, which carries oil vapor and will coat the IC and pipes with oil.
Since your PCV plumbing has been removed, oil currently is not being dumped into your IC by the PCV.
Your turdo seals could be shot and allowing engine oil into the compressor section of the turbo and being pushed into the IC system.

This could also explain a drop in oil pressure.

Thank you. I started my tear down. I'm cleaning thing up a bit and trying to see what I see that needs work. I ordered my oil pump but it won't be here till Wednesday. I'm checking all lines and seals. There is an oil leak. But I can't tell where its coming from. It literally sprayed my radiator when I had the car running yesterday. I was trying to see if there were any other things I could notice. I went and got some purple power so that I can clean it up a bit and it'll be easier for me to find. Anything else I should check while im at it?

Okay so I found a few wires that have no ends and one wire tucks back in. My head lights are permanently on. My power in the car is run through a switch next to the ignition. It originally had a clutch fan but my fan are also ran from that switch. That explains the loose wires. Is there a diagram that shows me which wires are which? I intend to solder the wires and do a shrink wrap. Any suggestions or other ideas of how to do it right without replacing all wires?

Oil pressure is normal until oil gets warm. 45-50 at 3k and about 5 when at idol. Then when its warm it drops and when it drops, the car shuts off. Then it'll start right back up but the second I give it any gas, it shuts off. There no noise coming from the motor even when its running warm. I have boost, oil, and water gauges.

One thing at a time. First figure out why the car is dying. Have you run the diagnostic check for codes yet? Did you find and fix the boost leak?

I fixed the boost leak. And it was only throwing an o2 sensor with diagnostics.
