While you are wrestling with valve problems, "a knock in the engine
near cylinder #2" makes me cringe!!

There are two sounds generally associated with internal engine faults.
One is a clack or rattle sound associated with the valve train - and
most times being related to a lifter being pumped up. There other causes
of valve train noises, but that's the most common one. The other sound
"IN" the engine is a "knock". That is a very distinctive sound, and
usually signifies imminent bearing failure - either a rod or main
bearing. There are stethescope like tools that can beused to listen deep
into the engine and help isolate these sounds and give you a clearer
picture of what is happening and where. Get them at the local FLAPS. You
can also use the a socket extension for a ratchet wrench with one end
placed on against the engine, and lean your head over so the other end
is on your jawbone just below the ear. You will hear/feel the sound more
clearly.

Good luck.
