I am intrigued. Attached is a photograph of an oil leak from the front of the engine of my 2010 Boxster S. The pics show the front upper and lower oil pan just below the front engine mount when the leak was at its worst. Of course this is the 3.4 DFI engine, the car is pristine and has only covered 33,000 kms.
The history is that the leak was diagnosed as a faulty AOS at the last service a month ago and the AOS was changed. But the leak persisted, not a lot, occasionally a spot on the garage floor but not always. Looking from above and from behind the front seats the engine appeared to be completely dry above the upper oil pan. Also the PDK had become very sluggish and unpredictable when taking off from a standstill but otherwise the car appears to run fine.
When I reported back to the dealer they advised that both problems were caused by the AOS. They said that the new AOS was a faulty part and happily agreed to replace at no cost. This has now been done and after a hot 250 km run the leak has stopped but there is still some oil residue around the lower pan. But nothing like in the attached picture. The dealer advises that this is oil leaking from the intakes left from the bad AOS and that it will clear over time.
Miraculously the PDK is back to perfection so I guess the dealer knows his stuff. But does this make any sense?
Happy Thanksgiving, Folks!
Appreciate your thoughts on this situation.
I'd been noticing infrequent leaks - looks like oil but doesn't seem as thick or viscous, from the rear suspension area of the driver's side.
I checked the oil levels on both the dash indicator (varies between at the MAX level to mid-way between MAX and MIN levels) and the dipstick which is higher than mid-way.
I'm not so sure if this is really oil but is brownish and smells like a mixture of dirt and water.
I peeked under the car and have attached photos of the leaky area and it's cleaner sibling on the opposite end on the passenger's side rear suspension.
1) What is this part that is leaking? Is that really oil?
2) Can this leak be plugged or should the part be replaced?
3) If it is the struts, time to swap the rears out too? I'm looking at the fronts soon, so wondering if it is time to replace all 4?
Here is the leaky part - on the rear of the driver's side.
Here is the clean part on the rear end of passenger's side
Thank you for your valuable time here during the holidays.
Started to change oil on my cayenne turbo and found major oil leaks on front right side. Oil was almost driping from generator/alternator. But as everything is built so tight together it is allmost impossible to locate the cause. I think if it would be the turbo it would be more back to the car? Any suggetion what to look for or how to identify the oil leak location?
Hello there, my car is an early 2004 996 C4 Cab, 3.6L, 85k miles.
Good stuff on my DropBox folder: https://www.dropbox.com/sh/p62gwxshg2zath4/0wYS9yrgfv
Engine has not been started for 4 months. Actually it has been on a huge container for 2+ months and just few weeks ago I got the time to start working with my car again.
Just before taking these pictures, note that I did wash my engine and transmission while they were still connected to each other, that might explain the glossy oil spots near my IMS (or not).
Four months ago, underneath the car it looked that I get a tiny amount of oil after I drive around 500 miles, sometimes even a drop of oil to my garage floor if I drive a lot more. The drop comes right to the spot which usually indicates RMS/IMS leak. Then again, my AOS has been spitting lots of oil out from the connectors and the drop might originate from there too, impossible to say as front left side of the engine near AOS was so full of oil and gunk.
I've changed my oil now twice, both the oil and filter ripped open has looked really really clean but this is based solely on human eye :-)
I'd like to get a few second opinions to my questions, hopefully this thread is usefull to others too.
1) How does my RMS / IMS look in general?
I'd say the leak is reasonably small, most gunk originates from clutch, would you feel the same?
2) Would you change my RMS or just leave it be?
It has already been changed once at some point.
3) What exactly seems to be leaking here?
To me it seems to be the IMS, but strangely enough the bottom part right below the IMS cover was completely clean (just zoom the images and remember that I washed my tranny and engine just before separating them).
4) Which bolts would you change while doing the IMS?
Looking at the pictures, many change bolt numbers 4, 5, 6 and 7, how about you?
5) Curiosity question, what parts are not original?
My RMS must be new as the part number is 997.101.212.00. IMS looks old, part number K.99602401 (?). Also would you also feel that many of these bolts have been changed as they look past year 2004 bolts, right?
PS. I have a new RMS, LN bearing + tools waiting for the installation..
Big Kudos to everyone who got this far, hope you'll inspect my DropBox picture folder too!
