If you do keep your cracked a bit it should be checked regularly.  After the initial threads on this several years ago I decided to crack mine open 1/2 turn.  After several weekends the motor just didn't seem to be running right so I started investigating filters, etc.  It turns out that my bleed screw had worked itself into the full open position, I guess cause by the engine vibrations.  Tried tightening the assembly, didn't help.  I now just keep mine closed, it will stay in that position.

Thanks for all the information.  I changed the filters today (Racor, fuel pump and engine).  The bleeding went well, although I had to go back and bleed the engine filter (top nut) a second time.  Then bled the knurled "wheel" at the injector pump a second time.  Boom, the pump slowed down right away.  Ran the engine in gear for 1/2 hour at the dock (I just had foot surgery so I'm not yet cleared to take it out).  Ran like an Elgin clock.  Next stop: stuffing box and new water pump.
