Wet Intake

[seafeye]

Top of plenum looks wet. Trying to figure out why i have the Dreaded P1128 code. Oil seperator looks dry but top of plenum is wet. Any idea's where this is coming from and if this is a problem?
Car is a 1999
58,000 miles,
Engine replaced at dealership at 30,000 miles.

Also when the dealerships replaced the motors did they just do a R and R or did they swap over the injection etc from my old motor?

Thx

Not to be a smart ass or anything but I would run my finger over the "wet" spot and see what it taste like. If it taste like oil,I would bet it was from the oil seperator,mine looked fine and I had "wet" spots showing up from the oil seperator.
