New mk3 trying to learn a bit
 

This is what my engine bay looks like. The guy I got it from says it was like that when he git it. I was hoping someone may recognize a few parts as I don't really know what's been done to it. Also, I was curious to see if a boost leak could cause a loss if oil pressure, cause the turbo to smoke a bit, and eventually cause the car to shut off. Any and all coments are welcome. This is my first supra and hopefully I can make it work for me.

Also, what are these? They had white smoke coming from them earlier. Does something belong there? (The two holes)

They are the nipples for the pcv hoses that run to the intake. The bad thing is that by having them uncovered it allows for dirt to have a chance to fall inside the motor. Its to bad cars get people doing mods on them that are from a gain in performance.

Thanks. I appreciate it.

You might have some electrical problems in the future if you don't put a shield or a blanket on the turbo. It looks like it's cooking the wiring harness in that picture.
Fix the pcv system, clean up the sloppy wiring and it looks like a really good start. Those parts aint cheap. Hopefully whoever put all the upgrades on it put some good stuff inside it too.
Seriously, fix that wiring.

Thanks. I didn't notice that. In the morning, I'll take care of the wires and the boost leak. I think my intercooler pipe came off but its also losing oil pressure. That's my main concern.

If you think you are losing pressure, look up the correct specs and install a mechanical oil pressure gauge and check it to make sure it's not a gauge issue.
If it is a gte block, the engine uses a low pressure oil system. I think at idle oil pressure is only around 5psi when hot.

Its normal psi till it gets warm and then it'll drop pressure and shut off.

So the car wont idle when warm? The oil pressure drops when it is stalling from an idle? Your oil pressure is not causing your car to shut off, your car shutting off is causing your oil pressure drop. Sounds like when it goes into closed loop its not idling.
Time to check for codes. Welcome to the "what the kcuf is wrong with my car now??" game. Round one.

Lol... how do I go about checking my codes? If I put breathers where the holes are, do you think that it'd work or do you think it'd be best to get the vacuum lines that go to the intake? Also I'm getting white smoke on the turbo where the oil line meets. Almost like there's a leak but I'm not seeing a leak unless its on the motor side. Also, my intercooler boot came off. Idk how long its been like that. Today is my first day to really inspect the car for myself.
