Right now, I've come to the FINAL conclusion that the EGR in addition to the turbo's re-design (somehow) caused the carbon buildup in #1 and #6 cylinders and in addition to breaching the head gasket, the rods bent/tilted toward the buildup on the exhaust valve as a result of the continued POUNDING of the piston on the caked up carbon on the exhaust valve. THEN, after enough carbon was formed in the cylinder; THE OIL RINGS STUCK, causing the oil consumption problem. Therefore, I am in the process up using "snake oils" to see if I can get my rings unstuck, IF they are stuck like I suspect."

The issue for the oil consumption is that the rings don't stick, the bore goes oval in shape due to the piston cocking from the bent rod.

I drove mine for 2 years adding oil 4 litres per tank full- thats 800-900 kilometers and 1000 kilometers on the highway, i would add 2 liters halfway (when the low oil light came on- 2 liters down). But I had to do something it wouldn;t pass smog. I could trade it in for nothing or fix and drive for awhile ( I LOVE THE W140) and then sell. I may do that. MBZ diesels are BIG $$$ up here in Toronto. A huge cult following.

I did think about just straightening the rods, but they would bend sooner or later. OR straighten the rods, put 2 sleeves in #1 and #6 reuse the pistons and them dump the car.

BTW- I have 4 straight rods if anyone needs them.
