So, my electrical stuff in the car is now finished and wired up. 
The engine was in and for a moment started. Besides of a faulty TPS sensor (easy fix) I've been fighting against a coolant leak !!
 
  
  
  
  Terrible !
It appear the engine had some broke bolts, one of them being the coolant piping at filling neck to the bottom end. I took a chance with gasket sealing and I failed. 
Take all the timing stuff off, intake off, pullies off etc  
Got a helicoil kit, fixed that leak.
Than the leak from the "feeding" pipe towards the oilfilter housing started leaking. 
Replaced that O-ring and continued. 
Now I'm at (I hope) my last leak. It seems either rear bank head gasket or Block heater block-off plate. 
Put some UV-dye in the system to find it, but off course, now it's not leaking anymore. 
Ow.. and some powder coated valve covers for the KLDE.
