My TR4's been short on power for a week.  A dry compression test gave 
these numbers starting at the front -- 125, 35, 35, 125 -- and didn't 
change any wet.  No indication of oil in coolant, or of coolant in the 
oil.  No smoke clouds, even on hard acceleration, though for a year or 
so I've had some light smoke with a heavy foot.  I did have some valve 
recession I was wishfully blaming that smoke on, since the head hadn't 
been rebuilt when I had the rest of the engine done 3 years and 28K ago. 
 Oddly this past week it seems to smoke *less* than it had, since I 
spent more time looking for a blue cloud.

Any likely scenarios that don't involve spending the boys' college funds?
