T30 2002 Sudden High Oil Consumption
Hi all,
Our X Trail has almost hit 200,000 km with a recent cylinder head gasket failure, and cam sensors being the only problems in the past 120,000km of ownership. Oil consumption was always zero or close to that between services ie never fall below minimum in 10,000k's.
However now we are adding oil fortnightly and its disappearing off the dipstick at an alarming rate. There is also new signs of seepage from the head and rocker cover but not enough to leave drips overnight when parked. Prior to this the engine has been 100% dry.
What i did find was, whilst idling, I removed the oil filler cap on the rocker cover and whollah, it almost fired out of my hands due to being reasonably pressurised. Maybe an exageration there but the pressure was really evident. Removing the rubber line indicated some vacuum, but obviously not enough to vent the pressure build up.
What is normal here? Should there be any pressure in the rocker cover? Is there a PCV valve that could be the issue? I couldnt see anything in line rubber hoses. A diagram or a pic would be helpful if anyone has one.
Many thanks in advance.
--- Cheers
