And the second one sounds like noisy tappets, or followers, again only on a really cold day and it goes away after the engine has warmed up. I just adjusted the valves 2000 miles ago... or is it a oil flow problem?

the second noise is probably the valvetrain making noise waiting for the oil pressure to come up. I'm more familiar with the Cummins engines, but they do the same thing in extreme cold. Synthetic oil seems to help this problem a LOT for me. I've only had my 83 300DT a few days now, but I notice it behaves similarly on the coldest mornings when the oil is thick.
