Yes you're losing power, and it should be somewhat noticeable.  You want
to perform a compression test.  THey sell the equipment at almost all
auto shops, and it's a pretty easy check.  If you do find the cyl that
is leaking, check for broken rings, ring lands, and scoring on the walls
of the cyl.  If there is a broken ring land, you need a new piston, or
if there is scoring, you're going to have to either hone or bore the
cyl.  If you have to bore, you'll have to bore all the cyls.  THat's
where it'll start gettin expensive.
