Oil leak near Left side of engine(Driver Side)

[Brucelee]

I don't think high compression per se would generate a cam cover or valve cover leak. A head gasket maybe. Having said that, there are plenty of cars that have high compression that do not leak, certainly not RMS or the other leaks mentioned here.

It COULD BE the flat nature of the Boxer engine. Having said that, Subaru does NOT have a reputation for oil leaks.

Go figure.

It spews oil so you get that race car burning oil smell that will impress your true enthusiasts!!

Im almost positive my oil leak is from the Spark Plug O Ring, im planning on changing ALL my Spark plug O Rings with the Spark Plugs as well since it has 55k on it now...Question: Is the Bosch Platinum 4 (#4417) alright to use for my 01 2.7?

My oil leaking problem is due to the Spark Plug O Ring....My mechanic changed ALL 6 Spark Plug Tubes and O Rings(6- big/6-small). The leak is coming from one of the tubes on the Left side....Since my Box has 55k and the Spark Plugs needed to be taken out to access the Tubes/O Rings, i also decided to do my 60k service in advance...New Fuel/Cabin/Air,Oil Filter, New Brake Fluid(ATE Racing Blue), Oil Change, New MultiRib Belt, Topped of all fluids, New Spark Plugs(FGR 6), Clean out all drain spouts in engine compartment, Full System Check using Porsche Diagnostic Computer, Test Drive...$675 for ALL the above/Parts & Labor(Done by a Porsche Master Tech friend who works for 20yrs for one of the major dealerships in my area )...My Box now purrs like a kitty!!

I work on Subaru almost everday at the shop and can honestly say that at least 6 out of 10 car have front oil seal,head gasket or valve cover gasket leaks. One question- how bad do the RMS leak on 986/996?? Is it just a drop here and there or do they blow massive amounts out? I've seen NA cars that will leak five liters out in as little as 10km's of driving.

Interesting on the subs. We have had them for years and no oil leaks of any kind.

Anyway, the oil leaks on the Porsche motors are usually slow ones in my experience. I have had cam covers, RMS and valve covers adn they are slow leaks, not big drips.
