Did you go overbore on the pistons? Did you run a running in oil?

That sounds like a lot of oil consumption. Wouldnít the spark plugs give you an indication if itís burning an excessive amount of oil in the combustion chamber?

No overbore, and no run in oil. But I also drove very lightly first 5k kms

plugs do look like there's oil in the chamber but again im being told it's because it's too rich. I will do a fresh change now that AFR is sorted out and see how the plugs are afterward.

What I'm trying to really understand is whether or not running rich could cause that kind of consumption.

I'm not an expert, but from my own experience I know that a rich tune allows gas to essentially wash the oil off the cylinder walls, the lack of oil causes smoothing of the cylinder walls and loss of seal between ring and cylinder wall. The loss of this seal leads to oil consumption b/c you get oil in the combustion chamber.

If its glazed the bores from running rich. Which it sounds like you have. You will need to pull the engine apart to give the bores a light hone and re-ring. It will always burn oil until you do.

Youíll get a range of opinions on this but Iíve heard that you need to vary RPMs and generate some vacuum so the rings seal when breaking it in. I had 2 M54s rebuilt by a less than competent mechanic and amongst the many issues I had...I never consumed enough oil to force me to add a qt.

Sounds like you ran too rich of a tune to break the engine in, you probably washed out the walls like stated above.
