Diagnosis on '90 780 Burning oil... PCV? Turbo? Valve Guides? 700 1990

posted by  someone claiming to be riverol on  Fri Mar 8 12:11 CST 2002 [RELATED]

If you hear a noise like a vacuum leak on the intake side of the engine and this noise gets louder when you disconnect the IAC, would this not indicate a vacuum leak that sucks in air at idle to compensate when you disconnect IAC? Would this then account for the problem Robert suggests?
