2003 Volvo S80 Question: engine crankcase
Answer #1Bret Bodas from RepairPal Test Shop, September 08, 2010, 09:31Master
This may be a leaking crankcase hose under the intake manifold. I've seen it a few times on the XC90's. This repair is quite difficult, so I advise you take it to an experienced Volvo shop to address this.
