Having problems with your 2005 Volvo XC90 ?
I recently purchase a 2004 XC90 with over 200k miles. When attempting to change the oil (a long story) I noticed that the rubber hose connecting the hard plastic air intake(?) that crosses over the top middle of the engine to the cooler in front of the radiator was oil soaked, possibly rotten and somewhat distorted. There doesn't appear to be any oil leaks from above that would drip onto the hose. Could the oil be coming from the inside of the hose? Thanks
This is the turbo air cooler hose and most of them have some oil in them from the turbo. i would replace the hose and keep an eye on it, the problem may be a worn turbo. the turbo is sucking in oil, the turbo may need replacing but i would nt replace it right now, just replace the hose and keep an eye on the engine oil level, if the turbo is working and the engine is not using oil and you dont see smoke coming from the exhaust system when accelerating then just replace the hose for now, hope this helps.
