Reported cause
Ninetynine996's description of his car's problem is very similar to what I experienced with a cracked oil separator in my vehicle during breakin period.
Leading evidence: 'very similar' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'very similar' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Check floor the next morning....nothing' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

I cleaned the drip and check the floor the next morning....nothing.

Or you can go to the dealer and have the gasket replaced for a few hundred dollars and wait for the leak to start again.

Separator was replaced and the engine has been bone-dry since.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

After 47k leak free miles, I spotted my first oil leak last week.
Drove it last Wednesday for the 1st time in about 2 weeks. Spotted a small drip (size of a quarter) about 6 inches behind the drivers side rear wheel, between the exhaust and the engine. I cleaned the drip and check the floor the next morning....nothing. Dry.
I drove it again on Friday. Oil on the floor again. After another clean up...no oil drip.....drove it yesterday. Oil drip is back but now is a bit larger (2 quarters)...oil level or pressure look fine.....before I call the dealer, do you guys have any thoughts....cam cover?
Probably the intermediate seal or rear main seal. Go get it checked out regardless if it under warrenty have it fixed. It not then I wouldn't worry about fixing it unless you see a lot more oil of the floor. Then wait untill you do your clutch and get the seal replaced at the same time. Saves you a lot of money when you do them both at the same time.
NinetyNine996: A small leak from the solenoid cover is very common and does not need dealer attention. Most often, just snugging the 2 bolts a litte is enough to stop the leak. Most of them will sweat a little (not drip and if you get an occassional drip, I wouldn't worry about it. Or you can go to the dealer and have the gasket replaced for a few hundred dollars and wait for the leak to start again.
It could be a cracked engine block or a blown oil line or oil coming up from your garage floor. Stop with throwing out suggestions that are not even close to the symptoms he is having. The oil seperator does not cause an external leak, the RMS would be at the center of the engine and not near the wheel. It is likely that the oil came from the solenoid cover. The only other likely possibility is that one cylinder on bank 1 had an extremely bad leak of the "O" ring on the plastic sleave and that can be easily diagnosed by looking at the block around the coils on that block. The solenoid cover can easily be seen from under the left side of the car.
Seems we are holding Porsche to quite a high standard to make a leak-tight engine. I am a Marine Engineer, operated Nuclear Power Plants, rebuilt many engines and there is no such thing as leak free.
A few drops is no big thing. Maybe just cosmoline.
1999Porsche911: I disagree. Ninetynine996's description of his car's problem is very similar to what I experienced with a cracked oil separator in my vehicle during breakin period. Oil was accumulating just outside of the separator and slowly finding its way to a location as he describes, with similar quarter size drips, and no apparent changes in oil pressure (plus CEL light never came on -- in my case). Separator was replaced and the engine has been bone-dry since.
I'll make a note not to buy any engine you have built unless I want it to leak oil. Did you skip over seals/gasket and torque specs when you got your degree? Making a leak-tight engine is not a high standard; it is standard, common and expected.
The oil seperators (2 of them) are located in the bottom most part of the engine. A leak in one of them would not find its way to the top lefthand side of the engine so that it could leak down between the headers and engine. Again, this is based on the descritption of the leak we were provided with.
1999Porsche: Indeed there are 2 oil separators as you describe (part#996-107-080-54) for engine lubrication purposes. But the oil separator I am refering to is for crankcase ventilation purposes, of which there is only one (part#996-107-026-50) and sits on top of the crankcase below the intake manifold. This guy is the one that gave me the troubles, with symptoms as described.
Regards.
Could be the small rubber boot from separator to top of Variocam box. They crack in the folds and let small amounts of oil out and drip in the area discribed. 20 buck part and a good pair of needle nose plyers is all you need.
