Oh yes, you are right. They are cast iron.
Nevertheless, my engine consume up to 1 quart of oil each 650 miles in spite of all new parts (pistons, liners, rings, valve steam seals etc.). It was correctly broken in and I run it with semi-synthetic Mobil oil 10W-40.

It's not as the consumption would disturb me much because the engine really pull strong and run on german highways a topspeed of +200 miles. I am just curious to know what experiences about oil consumption other cast iron sleeves LT5 owners did.
