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?
I am starting to prepare my car for a track day at Chuckwalla valley raceway at the end of the month, and I was told that the car as it sits has oiling issues? My car is a 2003 Carrera. I bought the car last year with 74k miles and immediately did the following: LN IMS bearing, Waterpump, coil packs, spark plugs, all filters and fluids, clutch + flywheel and a stock AOS. In anticipation of the event, I am going to do an oil change from M1 0w-40 to the Joe Gibbs dt40 oil suggested by Jake Raby along with fresh filters. Is there anything else I need to do to not have oil starvation? Is this issue blown out of proportion? does the 2qt sump extension make that much of a difference? will it affect the streetability? I am running 200tw tires.
I plan to replace the RMS and IMSB on my 2003, Carrera, Coupe, 3.6, Tiptronic. I have read about the MB version of the Tiptronic requiring the removal of the trans/engine together while the ZF can be removed separately. Is this true and how can I determine which one that I have? I crawled underneath and could not see an I.D. tag. So far I have found conflicting information regarding the trans. in this car.
I'm looking for advice in maintaining my well kept 2000 Boxster.
In 2003, I bought a 2000 base Boxster with 14,000 miles (manufactured 11/99, 2.7L, MT) from a Porsche dealer in Massachusetts, where I primarily reside. The car now has just under 40,000 miles. So I've only driven it 26,000 miles in 13 years, and I have had no major problems. I had maintenance done by the dealer initially for about 5 years, but then switched to a more local independent mechanic with a good reputation, as the dealer was over an hour's drive each way.
Last year I bought a condo in Naples, FL, and decided to drive the car down and leave it there. My mechanic replaced the engine drive belt as a preventive measure before the drive south, and the car was excellent for the long ride. Other than that, over the years, I've mostly only had routine and timely oil changes, plugs, and filters. I replaced the top and the tires a couple of years ago. The CEL did come on at times about a year ago, but it could not be reliably diagnosed. The mechanic suspected an O2 sensor. But the light since went off and all seems well since. Sometimes I can get a puff of smoke when I start it, especially after it was sitting for an extended period, but this resolves when the car is driven more regularly. I believe I have a good storage protocol for the times the car is idle.
In recent years, the AC has been declining. The mechanic added refrigerant periodically, which worked for perhaps a year at a time. I am due for that at least, if not more at this point, as there is no cold at all now. In Massachusetts, this was less of an issue, but now I want to get that more correctly resolved. The AC seems more noisy than it was previously (up front?), so I imagine there's a leak or other issue.
Outside of the AC problem, the car is operating perfectly as far as I can tell. I drive it about 5 weeks a year while in Florida. It is in excellent cosmetic condition, barely a scratch, and always garaged. I'd like to continue to operate the car in this manner indefinitely for the next several years, and hope to spend increasingly more time (winter) in Florida as time passes. Does anyone have any advice for me as to how I should proceed with this car? It looks and drives like new. I'm not a mechanic. I hear and read about the IMS bearing, the AOS, and other issues. I've not had the brakes or clutch done, but they seem fine. Even the battery is from 2003 and the car starts right up.
So I appreciate any advice moving forward. Should I have some of these things dealt with preemptively, instead of waiting for a more expensive failure? I'd like to bring the car in for maintenance and hope I can find a conscientious and competent mechanic to assist me. Does anyone have any recommendations for a local mechanic and/or the dealer in Naples? Would anyone recommend going to an "AC specialist" type place for that one particular issue over a mechanic or the dealer?
