im hearing a knock, from what i can tell w/ a stethescope is comming from #4 valves.  it comes and goes, when reving high (like in 3rd gear about 4000rpm), it will start, then go away after a few minutes.  Pulled the valve cover , #4 intake was a little tight, so I loosened it to .07.  All others were ok.  Is it possible to have a stuck valve, without doing crazy damage to the piston or valve?   Will something like seafoam possibly help?  Could it possibly be a loose rocker assembly?  any enightenment would help!! ???  :bricks:

Awww, that's just your engine letting you know it is still there...like saying "Hi!"   :hammerhead:
IFS is best kept at ambient temperature in a pile of scrap in the backyard.  When kept under a functioning vehicle, it tends to greatly diminish said vehicle's offroad ability.     -reklund5

sounds like a timing chain slapping around,  the reason it sounds like its coming from #4 is the echo
