I finally got the system completely hooked up and fired it up.
Turbo 2.0 SPO w VJ-11 + stock mani + adapter etc etc.

I hooked the A/F GUAGE onto the post cat O2 sensor. From the manual it looked like the grey wire (going into the PCM) was the one to hook to, this traces to the black wire on the O2 sensor (as Jeff mentioned). The A/F guage read nada, nilche nothing. Not sure why. I checked the voltage and it wasn't ground, and it wasn't rail (+12v), i've got an old analog voltmeter so I couldn't tell exactly what the swing was (I know I should have seen someting form 0-1 V) . I'm assuming this was the right one. I also was getting a ton of smoke and oil drops were coming out of my exhaust flange (downpipe) and out of the wastegate shaft (on the housing).

Seems like maybe the turbo I bought was blown, no oil on the inteake side though. Also the boost guage didn't regierter anything either. I only took it up to about 3K as it was 11pm at night here and my garage echos down the street.

I proactivley purchased a rebuild kit but it didn't have any o-ring style seals. A bunch of snaprings and bearings etc. Anyone here actually rebuilt one of these things before, are there o-rings?

Also if you are running OBDII are you using the pre or post cat 02 sensor. On the actuall sensor for all escorts it seems there are two white wires, a black and a grey one. Am I correct in hooking up to the black one for the 02 sensor (grey at the harness).

Excuse my spelling errors as it's 11:45 Saturday night here :)

Thanks,
Tim

An anolog meter has too much of a load to test for volatage on a O2 sensor, it must be a DMM. And like marclar said, you want to use the first O2 sensor, not the 2nd one.
The smoke and oil from the down pipe is a blown oil seal, it could of been bad to start, or worn and ready to blow, and the low oil return leval took it out completely. Or the oil seal was perfectly fine, and your oil return backed up.
To build boost you have to drive the car, if you just rev the car wile it's parked to 3000 rpm's, you wont build boost.

Just to follow up

I had the right colored wire just the wrong sensor (black going into sensor after harness) shouldn't I see some kind of a reding though on the second one if it was on the right wire? The DMM thing makes sense I didn't think about that.

In the rebuild kit I bought the all the seals it came with were snap rings etc. No rubber seals. I've never taken one apart do these parts look like all I need to rebuild the oil side.
