6.0 woes

HELP! I have an '03 F550 with the 6.0. Replaced FICM and INJ. two weeks ago and has been running great! Yesterday it took a dump, no codes, lots of white smoke and fuel dripping from exhaust. Any ideas?

If it is fuel dripping out, you probably have a cracked injector tip or a blown o-ring. If it is coolant dripping out it would be a blown EGR cooler. What are you using to read codes? Some scanners won't show you cylinder contribution codes, which could point you to the bad injector.

I have an OTC and it does show cylinder contribution. It had three bad injecters and a bad FICM and didn't run this horrible

. I thought it was coolant too 'til I stuck my finger in it, it's diesel.

Its possible one of the new injectors was defective and the tip blew off.

I don't know what else you want. Fuel coming out the exhaust is usually an injector leaking, so you need to do a cylinder contribution test to see which one it is or a compression/balloon test to see which is leaking and then replace it.
