Like jay-bird said, it's the injector cups. I've seen this problem twice within the past couple of months, unfortunatly on one of my personal trucks. It's best to replace all of them at once and get it over with. You're probably looking around $2,000.00. And go ahead and get the overhead valve job done while they are in there.

I had the leaking injectors with a 3406 Cat.You will find fuel in your radiator,and anti freeze in your fuel tanks.Its was the seals around the injectors.Ended up replacing the seals,and 2 injectors,and flushing radiator and dumping a full tank of fuel,about 280 gallons.Even though had engine warranty,still cost me 1500 bucks.
