Hi all,
I have a 2005 987 Base 2.7. For the last 11 months I had an RMS leak.
Drops a few drops of oil on the driveway everyday. (going to fix it when i change the cluth one day)
When this start about 11 months ago, i did my own oil change and over filled it to the top segamant probably either .5 - 1 full extra liter of oil by mistake.
I go and check the oild for the last few days and its still overfilled on the indicator after leaking all this oil everyday?
How on earth is this possible? I was anticipating having to top up?
Please shed some light on my confusion??!!?
Thanks!
I would have thought a couple drops a day would equal a litre in almost a a year? porschestar - Saturday, 2 February, 2013, at 12:32:12 pm |

I wouldn't even be so sure you are overfilled. Every single time I've had the oil changed on my Cayman -- which is now about 5 or 6 times in 4 years/16K miles, we have measured out what we put in according to the manual, and every single time it shows overfilled. Mechanic sez not to worry, and I have neither clouds of oil in my exhaust, drops in my garage, nor does the level ever drop below overfilled. In fact, I'd tend to believe the gauge doesn't even work except for the fact that one time we "only" put 7 quarts in it, and then it showed about half full, so we added the rest and voila! overfilled again. They replaced a perfectly serviceable dipstick with a crappy piece of electronics that might or might not even work. Well, hopefully I don't have a problem because my warranty expires this month. Yeah, I could take it to the Porsche dealer to inspect ... that's the Porsche dealer who sold me the car with "rust" on the wheels that they wanted to repaint and it turned out to be cosmoline. This kind of thing, together with the IMS and the clunking when reversing in cold weather and the fact that tall people can hit their heads on the roll bar in a 986 Boxster, are why it kind of makes me puke when I hear the fanboys talking about how great Porsche engineering. From personal observations ... the car is no better than mostly okay.

My manual refers me to the "Capacities" section of the manual, not to the dealer, and nowhere does it say to consult the VIN to get this info. In fact, in 4 years of ownership, this is the first time I have heard of such a thing. Where did you dig it up? And as for the car being delivered overfull, I thought that was a normal condition. How was I to know otherwise? As I recall, my 986 Boxster that I had only briefly (due to the tall guy -roll bar issue) was also delivered (used but serviced) from the same dealer and was also was overfull according to the gauge. That was the same dealer that wanted to repaint my brand new Cayman's wheels to get rid of the cosmoline. So far, I see an idiot dealer and a sloppy company that hides necessary information. Or not -- at this point do I believe you, or my manual and a highly experienced Porsche mechanic? And you guys act like I'm an idiot for not knowing this stuff?
Also a reliable measure of cold oil moisture content, which adds to volume. *NM* Laz - Wednesday, 13 February, 2013, at 7:43:52 am |

I'm not so sure overfilling is that bad. I overfill my motor by close to a quart ( I would rather have a cloud of smoke from an overwhelmed AOS than a spun bearing because of oil starvation) when going out on the track and with the motor idling, the oil level didn't even register on the dipstick, so I'm a little sceptical that a quart overfill will let the crank slap and earate the oil.
Porsche perscribes the proper level, i would hope, for a reason. grant - Monday, 4 February, 2013, at 8:04:14 pm |

boil off fuel, water, and other light contaminants. While oil may only average, say 175 deg (F), i am confident that as it circulates it gets well above that and gives off steam, which is eventually EGR'd (AOS'd).
in fact, i believe that failure to do this results in water and fuel contamination, corrosion, oil film weakness, and leads to many of the failures we talk about. fresh, clean, basic (as in not acid) oil is crucial. Fresh, acid, diluted oil is death. note both can be fresh.
