Huge oil leak top of motor 6.0
 

After replacing the oil cooler I had a coolant leak from oring on bottom of intake. After fixing that the motor developed a big oil leak somewhere on the top of the motor. Oil pools up by the turbo return pipe and runs down the valley to the bell housing, etc. The leak only presented itself after I replaced the oring on the bottom of the intake to the egr cooler. I only removed the bolts from the intake and lifted it to replace the oring. What could I have messed up? The leak is extremely big. Losing about 5 quarts of oil in 100 miles.

Did you check the oil drain tube off the turbo?

Yes. It immediately pools around the small housing that connects to the egr cooler with the two inch hose. Could oil leak from there ? I thought coolant flowed there.

How about the oil feed line? There is a small o-ring on the bottom.
