With the cleaned and adjusted FD/Air Sensor assembly back on the engine, I was able to start the car after some leaning out of the now functional lambda screw. However, the true culprit may now be surfacing: tremendous amounts of both white and bluish smoke from the exhaust, and after a couple minutes of warm up, a massive amount of oil is spewing from the PCV tube.

The oil pressure gauge is only showing 1 (bar?) on the scale of 4.

I checked the cylinder head oil return tubes and nothing was clogged or even dirty.

The oil separator mounted inside the top of the valve cover is clean, with the 3 mm drain hole clear.

There is no immediate sign of oil in the coolant or vice versa, however both of those fluids will be drained and inspected.

Has anyone had issues with excessive oil in the PCV line?
