New mk3 trying to learn a bit

[Meekmeek]

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?

[Meekmeek]

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

[El Supracabras]

Well, there ya go. O2 sensor readings are only used in closed loop (when its warmed up). Does it even have an oxygen sensor? Is it hooked up?

[Meekmeek]

How does the o2 sensor work? I just tried googling it and I foud a lot but nothing really eccplains it.
