If it's dirt, then maybe one of the additives can dissolve or otherwise clear up the issue after running it a bit. If it is simply marginal, say at hot idle (doesn't sound like your problem) then perhaps Marvel or merely a heavier oil would help. Most likely have to take the head off and replace it.
