i have a 2000 7.3l and the other day i drove my truck to town 14miles and noticed that when i parked it that there was a enormous puddle of oil underneath. thought it was the oil cooler but after further investegation noticed oil setting in my engine valley under the turbo/HPOP. any suggestions on what might be the cause of oil leakage

 

Hpop oring or turbo pedestal

 

it may be fuel. there are about 4 places under there that will leak fuel then run down the back of the intake and down the rear of the engine and off the flywheel cover. check real good and make sure its oil before you go tearing into it! my lift pump was leaking, water in fuel sensor in the back of the fuel filter housing, a loose line, and the o rings in the full drain valve! and i thought it was oil at first too..

 

Just had this problem on an 01 7.3, it was a loose fitting on the HPOP
