Hi Klaus,

That's good to know about the hardened seats in the head. I've been using 15W40 diesel oil and it still leaks a little from the rear seal. Oil pressure remains quite high even after several hours on the highway, but it seems to get dirty pretty quickly.

I'm still not convinced that I shouldn't pull the head off and have a look inside. Who knows, I might find a reason for the buzz at 3000 rpm (which would be a dopey place to design in a resonant frequency).

New gaskets for all the doors are on order. The wind noise is a bit much after an hour or so. When we went up to the north shore I stuck bits of yarn all over the windows to see what the air was doing. The airflow does not straighten out until it gets back to the cargo windows. On Mary's V70 it is pretty smooth by the middle of the passenger window. So sealing is going to have to do what it can. I did plug up the hole around the steering shaft early on.
