Oil leak on Subaru 2.5RX
Discussion
Just checked the oil level and found it was off the bottom of the dipstick. Further inspection reveals spattering from somewhere by the RH bank, over the steering column and cat - that would explain the slightly 'warm oil' smell from the car at rest over the last week. I can't get under the car properly, or see any further under the that bank. There's no sign of drips underneath or anywhere else on the engine, but it has used half a sump's worth in 500km.
Exhaust seems clean - tested it at a standstill, with full throttle uphill, and coasting downhill followed by short sharp busts of acceleration.
Its booked in to a dealer for mid-week but has anyone had any similar experiences? The car's a 1999 Liberty 2.5RX with about 120,000km on the clock.

Check that the PCV system is working properly - you should be able to feel a distinct vacuum against the oil filler cap if you take it loose with the engine running. If the PCV is plugged the crankcase will pressurize and then it has to leak somewhere. Frequently just fixing PCV will get the oil leak down to a tolerable level.
If it's the cam seal up front, you will probably want to replace both seals (both cylinder banks) and the cam belt. This would not be a job to put off or have bodged in any way, IIRC this is an interferance engine so if the belt breaks you will damage valves, etc.
If you have facilities, clean up carefully and spray some powder (like athelete's foot cure powder) near the joint that's leaking, this will facilitate finding the leaking joint.

I have a similar problem that hasn't been fixed by a cambelt and seal change... So where is the PCV?? By PCV I mean in general a hose leading from the crankcase (usually from a cam cover, but not always) to the intake manifold. I do know the 2.2L in my Legacy has a PCV valve as such, I bought a spare but have not yet changed it. A good manual should show where it is. I do not know if all Subes have a PCV valve per se.
Again you can check function just by feeling for a vacuum against the oil fill cap with the engine idling.
Frequently the hose itself will fill up with sludge, you can clean it or replace it, sometimes the cam cover also needs to be removed for cleaning.
Loss of proper crankcase venting will generally cause oil leaks or aggravate them anyway.

Well the dealer had a look, and suggested the camshaft seals and timing belt cover seal (?) Got them to do it whilst it was having a service - apparently they've seen a few on engines with relatively low mileage. I asked if they's checked any blockages in any vacuum pipes and they confessed to not having done so but said it shouldn't matter.
The damage? Including the service and changing front discs and pads, and some small nonsense the total came to just over AU$1000, which is about GBP400. It does run better and has had some fettling in the tracking and steering too.
If its not solved the problem, I'll let you know.
