Most likely the turbos smoking. It happens to them all, its just a matter of when. That may be the reason the motor was taken of the streets, in japan.
Leave the "engine restorer" on the shelf, at the parts store, where it belongs.
I dont thing thats obvious. I have seen many fresh motors struggle to get the initial oil pressure. Ever see how they do it on an american V8? With a drill jammed down the dist hole to turn the pump.
This is before you start the motor right? Cranking speed may not be enough to prime the pump and entire system. Try using a drill or something similar to turn the pump to prime the system.
Idle is set by the computer with the ISCV. If the idle is out of spec you have an issue, that turning a screw is not going to fix.
What is the problem?
They are the same thing.
Depending on what your specifically talking about, there are many different styles. Toyota uses a clutch type and a torsen type. But it all boils down to "limited slip". Posi or positraction is domestic term for the same thing.
EDIT^ Right like he said.
Your readings are;
12.3 AFR at 25 mph
12.5 AFR at 15 mph
Thats painfully rich. You need to be somewhere around 14.7 AFR to correctly light off a cat, and pass smog. Remember these are cruse readings, those are semi acceptable readings for boost, but you will never pass smog with cruse reading...
The speedo cable starts at the rear section of the transmission, then makes its way forward, behind the head, then through the firewall. Easier to find from underneath.
NOX should not be that high at 2500 rpm without any load, even with an inop EGR. The EGR is only going to open slightly at the beginning of the free rev. As the motor is held at 2500 the egr will shut again. The EGR is used to lower NOx under cruse loads. Which this test does not cover.
It looks...
