Ah - the old "we did the top end" problem.
Answer: RINGS
But get a leakdown test to confirm!
The compression test will tell you which hole is bad (if in fact only one
is bad). A wet test will make your compression go up if the rings are
marginal but not toast.
A leakdown test will confirm whatever the problem is.
Then you start your teardown.
