View Here : Xc90 Oil Leak
Volvo XC90: I have a volvo xc90 2004, which is leaking oil. The PCV breather box is mounted to the block, under the intake manifold. I would have that replaced. If there is sludge in the engine, the passages going to and from the breather box may also be clogged, in which case the oil pan would need to be removed and cleaned out, but I would start with the breather box.
XC90 leak at the oil fill cap. A leak from your oil fill cap could mean that you have excess crankcase pressure and the pressure is finding its way past your old, tired oil filler cap gasket. Contained in that crankcase pressure are blowby gases (from combustion) along with hot oily vapor (which is essentially the gaseous form of oil).
XC90 Oil Leak At Charge Air Cooler. Go figure. Vapor makes it past the cooler condenses somewhere in the throttle pipe and dribbles down to the lowest point, thanks to gravity. That lowest point in the connection between the charge air cooler and the throttle pipe.
Oil leaks in the 2008 XC90s with the 3.2 liter engine are often due to a bad seal in the drain plug - the metal washer in your drain plug can only be tightened a few times before it loses its ability to seal and should be replaced periodically to prevent leaking. Replacing the metal washer should only be done when you change the oil in your XC90,...
2003 Volvo XC90. first had to have seals replaced for an oil lead, a few months later another oil leak; had oil trap removed. Labor for this very expensive, first had to find the problem, so I paid that labor. Then they ordered the part and had to pay the labor for repair, nearly $1,000 in labor alone.
Motor oil: Oil leaks at the front of your vehicle can be indicative of a wide range of problems. These include a worn gasket, corroded oil line, improperly attached oil filter, or a stripped or leaky drain plug. Before driving further, be sure to verify the oil level in your vehicle is not dangerously low.
