Small oil drip on oil filler tube.


Recommended Posts

Hi all,

just been topping up my hydraulic fluid and noticed a small amount of oil on the engine RHS. Felt a small drip below the join in the oil filler tube, its not much but just wondered wether this was common or an indication of anything else, or nothing to worry about.

Thanks, Timbo

Porsches leaking oil = common. that's how you can tell it's a real Porsche. :lol:

what model year is this car? how many miles? has the Air-Oil Separator been replaced (yet)?

if you don't see drops of oil on your driveway, it's probably nothing to worry about. have you needed to top off your oil, or has the level stayed the same?

depending on your mileage and model year, you may want to proactively replace the AOS with the latest model. they seem to go at about 60-80K miles on earlier Boxsters. earlier oil filler tubes were also known to crack and introduce vacuum leak.

if you have no Check Engine Lights (CELs) and the car is running normally, i would just keep an eye on the leak and your oil level.

Thanks Chris, the car is 2003 2.7 with 50k, no other issues regarding this particular oil leak....no loss of oil etc, although I do have an axle shaft oil seal leak but thts another matter. out of interest does the AOS become blocked? what actually goes wrong with it, I find it hard to imagine its a complicated part.

i'm not sure exactly what happens to the AOS. but suffice to say that it does not do its job of separating air and oil (vapor) and ends up feeding oil into your engine (not good). you will know when this happens because the resulting cloud of smoke will engulf your neighborhood (not kidding).

Found out today that my Oil Filler Tube is leaking as well. Is this a big job to fix?

Also, once replaced, will this clear the CEL i'm having? (Have asked the garage to pull codes for me).

Cheers,

Mike
