Sam,  when I was an aircraft mechanic in the bad old days, we would
often get at least temporary relief for a leaky valve, particularly an
exhaust valve by performing a procedure known as "staking the valve" .

Basically "staking" consisted of nothing more than (1) moving the rocker
for the valve for access and (2)  putting a block of oak or other
hardwood against the end of the valve stem, and giving it (the block of
wood) a good hard whack with a heavy ball peen hammer. This would snap
the valve open momentarily, then it would "slam" shut - not move
smoothly to a closed position as with valve train operation. If there
was any crust, corrosion, debris, etc, on the valve face or seat, this
tended to crush the material and remove it so the valve would seat
properly again. Sometimes worked, sometimes didn't. . But it may be
worth a try on your vehicle before tearing into it for a valve job.
