I have rad on here where guys are seeing oil residue or heavier on the blue hose for the intercooler and have done a ccv mods. My leak is not on the blue hose area but is at the front top of the engine on the cast intake tube/plenum where the plastic pipe clamps on. Is that the same issue or?? It is not heavy but is more than a mist/residue.

 

Yes--it's from the same source--the intercooler/turbo piping.

 

Yes it is the same. I replaced mine and when I removed it I was surprised to see how much oil had accumulated in the intake elbow.
