My 03 Turbo does this. I have some half baked theories as why but since it has done this since I bought the car in 09 and after having put 90K miles on the car it has not be a real pressing concern to get any senior tech input. But I would like to know...car goes in for new tires soon and if I can rememberI I'll ask about this behaviour.
Some months back I asked some experienced techs about trouble shooting/testing the functionality of the front differential on a Turbo. They said they do not bother and had no functionality tests to offer. They have replaced a few but the trigger was just the things were noisy. Afterwards the replacement was not noisy.
Not quite sure what you are saying here... you think I need to set money aside because you think these numbers are so bad I'm looking at some serious engine work down the road ?? Do you have any experience of these numbers leading to such an outcome ? I think you are fine, but what happens when you "start tuning the car" and put the engine under additional stress? What happends to those leakdown values then? All I was saying, is if I were looking to buy a car, and did a PPI and got your values, I'd take a pass and look for another car with a narrower range from the leakdown values. I think you'd be looking for a car for a long time. Leak down test results are not very definitive unless compression test finds a low cylinder. Then leak down test is used to ID probable cause of low compression. With these engines oil jets squirt oil onto backside of piston and this oil will work to help seal piston and cylinder. Some cylinders, the good ones, got a good shot of oil, the lower ones not so good. But once running everything will be ok. As long as compression test finds no out of spec cylinder leak down test waste of time and money. Sincerely, Macster.
Might be able to help #3. My 03 (bought used just a few weeks ago) was in for this early on while with original owner. Porsche mech. managed to address several rattles/noises that in one case IIRC sounded like it was coming from the passenger's side A-pillar but was in fact the sun roof. I have print outs of what was done. Involves felt strips in various places but I can assure you car quiet now. Send me email with your fax number and I'll send you copies of the work receipts with descriptions of what was done. Or if you prefer, send me email and I'll respond by typing in the info. Do not have the paper work here now. AT home. Oh, do not think front (or rear) suspension stiff. Car came with new 18" Continental tires and I used quality tire gage to ensure they were properly inflated, at cold temperature -- from sitting outside under carport overnight. Sincerely, Macster.
While some change their car's oil that (3000 miles) frequently, not all. In fact I would hazard a guess most don't change oil nearly that often and may not even adhere to Porsche's oil change schedule. Recently in a market for a used Porsche and found several used ones. Looked at one Cayman S with less than 10K miles but car put into service Sept. 06 and has not had one oil change. Read a Porsche magazine's contributor to reader's cars efforts to find a nice used Boxster and he wrote he found a lot of cars but when he asked about services, oil/filter changes, he was often met with blank stare or with the reply the car had never had one. Europe usage is different. Better (higher octane) gas and less time idling, sitting in traffic. Cars also I think get driven more. Tech at local dealer just back from engine training (on new DFI engine) told me in Europe these cars bought to be driven, here they are bought to be stored. My '02 Boxster -- since I bought it new -- has seen 5000 mile oil/filter services and will continue to do so. Recently car reached the 222K mile mark and runs as good as ever. My '03 Turbo -- bought used -- was treated to its first oil/filter service since in my possession -- last one done last Oct. but I don't know at what mileage (I bought car with 9400 miles on it) -- at around the 10K mile marker and will also receive 5000 mile oil/filter services. Sincerely, Macster.
At this stage just a shaft R&R not likely to meet with success. By continuing to drive car, run engine, likely some metal debris has been spread through engine. Before undertaking any restoration of this engine, the oil filter housing would need to be removed, the oil drained, and the camshaft covers removed and signs of any metal debris in any of these areas looked for. If none found, and I mean none found after a very thorough examination with a strong light and by someone who knows what he's doing and has done this before (and would be on the hook to make good the engine should he make a mistake and miss something), then the engine could be removed from car, disassembled, cleaned up and all worn or damaged parts replaced, engine buttoned up again and installed back in car. Not cheap. And not for the learner... Unless the problem proves to be superficial -- like just a bad/noisy chain guide -- and this can only be determined by some disassembly of the engine -- your best chance for getting the car back on the road is having a new Porsche engine installed. 2nd best chance would be to find a good engine from a wrecked car and have that installed. Sincerely, Macster.
From the description and such sounds very much like an IMS failure. Not all failures result in a breach of the engine cases. I saw one Carrera engine with an IMS failure that the damaged was mild enough the engine was going to be rebuilt at the dealership. In your car's case, though, rebuilding is out of the question. With metal debris in teh filter housing, with one or more oil scavenge pumps seized from the debris the metal debris contamination is just too widespread and into too many critical areas to make the rebuilding anything but a very very risky undertaking. Either you're faced with sourcing a new/replacement engine from Porsche or some used engine from another (private seller or salvage yard) source. You can if you go the second route consider having installed a bigger engine. As you have already found out, Porsche not likely to offer any help. Unfortunately, with used low mileage Boxsters there is a very real risk the engine will fail like this with the second or 3rd owner. Upkeep, servicing, useage doesn't seem to play a role. The only common denominator is the cars usually have low miles -- under 50,000 or 60,000 is suspect -- and that's about it. Sincerely, Macster.
