DAS4

experience...

its oil leaking from behind the bumper cover lower grille. i removed the grille but can't see too deep inside so i'll need to remove the cover. i was driving two days ago and under full throttle heard a "pop" on the drivers side then experienced a loss of boost. it since has had slightly lower boost and lurching under full throttle. not sure if i ruptured the driver side smic. somewhat hard to do, but possible.

makes me think though: if the intercooler or hoses are filled with that much oil that it'd leak beyond the bumper cover, are the turbo seals leaking that badly too? or could it be a PCV issue? i've had and wrenched on several B5 S4's so i'm sure the logic behind this setup is similar. any advice you guys can offer is greatly appreciated... i'll try to remove the cover tomorrow morning...
