Hard to see from this photo, but the transmission bolt was so over-tightened that it has been stretched thin -- deformed -- near the shoulder.
Take it apart in assemblies:
Camshaft (Synch) sensor, re-wired at some point, pretty sloppy.
Oil pressure sensor, leaking adapter for oil pressure switch.
Really weird: loosened this fitting, and it
sprayed oil out. For some reason it's holding oil pressure in this circuit...
This is also plumbed for extra engine sensors:
Air Temp -- intercooler inlet
Air Temp -- intercooler outlet
Oil Pressure
Fuel Pressure
Strangely, this car has stock chassis fuel lines -- smaller than -6AN -- but after the fuel filter it jumps all the way up to -10AN in & out of the rails. Then it chokes all the way down to -4AN for the return line out of the FPR. Doesn't make a lot of sense.
The cylinder heads' intake port work actually looks really nice. Except for the speckles of metal stuck to the port wall.
Really nasty oil in the turbocharger scavenge system.
