I just recently had a remanned short block installed after a failed FRP sensor filled the crankcase with fuel, caused a runaway, and ruined my 6.4. Once it was tore down they found some failing injectors and some pistons that were starting to show some extreme heat conditions so we replaced injectors too. My question is last night I was out driving around and two things: It rolls a little black smoke at a normal, easy acceleration from a start..?? Then later on a got on it from about 10mph to 80mph at WOT and instead of being a dark black smoke it rolled kind of a hazy gray smoke?? Any thoughts? It's got about 500miles on the new motor...
