The radiator has plenty of antifreeze (nice and yellow).

There is no oil in the coolant.

I do suspect the head is ill.

Shall I have the timing chain replaced "while in there"?

This weekend I'll check the compression pressures between cylinders

BTW - there are drops on the driveway, but no big oil spots.
