The blowby is above normal in comparison to my 760. When you pull the dipstick oil even splashes out.
I know that driving a cold D24 straight on the highway is far from ideal, but what can you do. I shift as fast as possible and only accelarate to 80km/h so about 2000-2100rpm in overdrive.
It always starts, just a little rough when dead cold. Sounds like its missing on one cylinder for a minute or two.
But the compression test should tell us more. If it's low, for example on cyl. no. 6, which is my guess because of the higher thermal stress, I'm going to swap the engine and set this one aside to live another day.
