Codes p117 and P1338 and red oil light on?

After replacing the pct which is on top of the valve cover, which has the sorting and diaphragm I started the car and it smoked like crazy, hard to say if blue or white. Coolant and engine oil full. Left it running 15 minutes then it cleared. No red oil light came on. Then I started it this am and no light was on then took it on a drive and was fine. Got into my driveway and parked and it threw the smoke puff again, again not able to see whether its white or blue. Then goes away after a while, could be valve stems, strange on 90k, I sold many of these without issues of smoke. Have flushed motor before then installed new filter and fresh oil. Then after a while red light came back. It only does at low RPMs, goes sway soon as I hit the throttle.

Yes, I thought so too. I thought about the turbo but there was no way to tell without removing it. Too much headache. Putting an oil gauge on these is pain the behind. No room. Plus, you have to remove a bunch of stuff to get to it and then if you want to run the car you have to put it all back and that won't leave room for the gauge. It's not worth doing anything to it unless someone wants to spend time and remove the oil pan and look. Even if the oil pick up is clogged up, the smoke is another story.

Car is strange. I changed the PCV diaphragm. Anytime I start it either ton of white smoke from exhaust for a while, or bluish when left idling for an hour. No antifreeze smell. Sometimes I start it and there is zero smoke. Oil is clean. Oil pressure light doesn't always come on. I will check the connector again. How does the light work? Does it have 2 pins and jumping it can confirm all is working from ECU is light does not come on? I want to make sure if it is a pressure issue or a ppm issue.

So help me understand. When the pressure is normal the sensor wires are grounded? And when it senses low or high oil pressure signal is sent out and the ground gets cancelled?

I tested the wires with ignition on and all show power (+).

I disconnected and started the car and there is no code for it yet.

It is strange. Car is super powerful, no misfires or any loss of power but driving it, it's a puff of continuous smoke.

All of them have power, none have ground. Ugh

Yes I know. But I tested it with the probe and that is not the case. Every one of them have battery power, none are ground.
