Greetings guys. Our rig just started leaking oil around the front cover but the fan keeps spreading the oil so we cant determine exactly where it is coming from.
It only leaks after pulling loads, and leaking is limited to how much work it does. We have no experience with this newer engine, and want to research the possible causes of this leak before attempting to open her up and take a look. Need your help guys. Schematics/diagrams, ideas, suggestions any and everything you may be able to offer on this is welcomed.
Thanks in advance. Front structure leaks are common for that year, as well as head gasket leaks on the drivers side rear of the head.
You could have front cover / cam cover leaking. A shop can do a diagnostic for you where they will steam clean the engine, inject dye and then black-light it to determine the origin of the leak(s). Usually about an hour for the diagnostic. A complete engine gasket overhaul will run you about $6500-$7500 depending on who does it. You may or may not need to go to that extent.

If it's high mileage and is leaking at the head gasket, too, you may want to consider having a dyno run on it and using that information to decide on what next steps to take. For instance, if the dyno (and blowby) are good, you could probably just do the gaskets and save money, but if the dyno is poor, you might as well get the engine rebuilt. One problem with the ISX is that the cams must come out for the head to come off. This almost always means radiator removal and sometimes hood removal.
Book time for a full gasket overhaul like that is about 40 hours in labor. If it's not leaking very much, just keep it clean and add oil as needed until you rebuild it. I would clean your front cover off with some degreaser then some brake clean to dry the area. Your front cover does hold oil in the bottom of it but when the engine is running it is being circulated through the area.these leaks can make things a lot worse than they are because like you said the fan is blowing the oil all over the place. Run the engine and try to catch the leak before it starts getting blown all over the place or disengage the fan. If that is the problem hopefully you don't have to remove your radiator /intercooler.lso more than likely theleak will be between hallway down to the bottom.good luck!!!!
