threw belt and oil leak

[hsjlawncare]

I have an 08 f350 that i recently installed (800 miles ago) an SCT tuner and dpf/CAT delete kit. I heard a weird noise yesterday and wasnt sure what it was. Truck ran fine. Today when i got back and parked it, i had oil leaking from engine. Checked it out and found that a pulley must've went bad and threw a belt. The belt is NOT the main one on the front of the crank, but a "rear" one. The pulley is tucked up to the left of the crank. There is a small pump on the left that dont have the belt either. Can someone give me soem info on what may have went or if the belt could have nicked an oil line. The truck seemed to run fine on way home too. I did get a U0100 and a U0115 code, but i think those were the codes it was throwing when i first put tuner in and I had the "wrench" icon. Was told they were tranny codes and no big deal. Please help if you can. Thanks

well jsut got it back from the shop. Apparently the idler pulley seized and caused the belt to come off. While the pulley was flapping around it hit either the crank seal and/or an oil line to cause a small oil leak. Not too big of a deal, but the shop bill was!! $950 of which over $550 was labor. Now I know im in the wrong business. I guess the good thing is that they got it in and had the parts in stock (Miracle for where I am in WV working) and I have my truck back.

I just checked to see why my belt is squealling, the same belt that you described, is stretched and soft, but still hanging in there. I need to change the belt's anyone have any advice on changing the belt's? Also, I heard something of a recall on that idler pulley, should Ford not be responsible for that? Thanks
