I'm stratching my head on this problem, my car hates having the oil level topped up, whenever I do so the oil blows out /leaks from somewhere underneath the engine and drips on the exhausts which then billows smoke from under the bonnetconfused
It seems to happen until the oil level reaches the lower mark on the dipstick, after which the car runs faultlessly, and uses very little oil.
I've had a good crawl around under the car but can't find out where the oil comes from??
Anyone had a similar problem, and if so how did you cure it?
Another possibility is that I have the wrong dipstick - is this possible with scooby engines?
The engine is a N/A 2 litre ej20

Hi have a look at this link, it also could be leaking from the crank seal.
I did not change mine just cleaned it out with carb cleaner, sorted.

Cleaning the PCV valve seems to have sorted it, won't know for sure till I do a long Motorway run, which is where I really noticed the problemthumbup

Great, have a look on youtube there are plenty links to show how the pcv works. (did you clean the rubber pipes aswell? they can get full of crap too.)
It might pay you too change the front crankseal next time the cam belt is changed.
How dirty was it? how many miles has it done?

Done 115k miles, PCV wasn't really that dirty, though when you 'Rattled it ' back and forth it didn't really rattle! After cleaning it rattles like a good 'unsmile I looked in the cleaning fluid [after cleaning] it was dirty brown with plenty of solid bits at the bottom. I used a kids small paint brush to clean the PCV insides with plenty of blasts of compressed air to help clear the ste. Surpising really Subaru don't mention the PCV within the service schedule [at least they don't in my workshop manual], it's small enough to warrant a change every 50K miles or so, to prevent similar problems.
Many thanks for your help resolving this.

Just had a thought on the leaking oil, if it has leaked via the front crank seal.
It may be worth removing the l/h cam belt cover and check the condition of the cam belt, just for piece of mind.

I cant see any oil leaking from the cambelt covers, an american mate suggested my problem could be oil leaking from the cam seals, having been told this I specifically looked in this area for the leak.
One positive though if the cam belt does break, I understand its a 'no contact engine' ie valves dont hit pistons if the belt snaps, not certain that this is the case, however if the belt does snap I'll change it immediately, coz I carry a spare cambelt in the car, seem simple enough compared to some others I've changedsmile

Problem definitely sorted - just done 370 miles over Xmas, Not an oil smoke cloud to be seensmile
Engine feels crisper/revier too, which is really noticeable at M-way speeds.
Many Thanks

Just checked out UKlegacy looks good though most of the Tech Q's were for the Turbo legacy. Not too much on there for Standard N/A cars - did download a pdf of the full legacy manual though thumbup
