Porsche Boxster S Ticking and sooty exhaust

I have just bought a 2007 987 3.4 Boxster S with 57K on the clock, and full service history from a dealer. After a week, the car developed a fairly loud ticking noise form the engine. Not loud enough to be heard whilst driving, but loud when outside the car. The noise is there whether hot or cold and the pitch rises and falls with the revs. There is also a black sooty deposit on the tailpipe. The car drives well with plenty of power, but is noisy. It also used 1 Litre of oil in 600 miles. There is no sign of oil and coolant mixing in either the coolant or the oil. The supplying garage have told me they can't find a fault, should I be concerned?

Hey welcome to the site! This is the 911 (996 gen) section of the forum. You may have better luck on the Boxster section of the forum. I believe yours is a 987, and that forum can be found here: https://rennlist.com/forums/987-981-718-forum-125/ ... I know, the numbering and naming conventions are confusing - we have Porsche to thank for that. However, the symptoms you're describing aren't normal. You said you bought it from a dealer, I assume it wasn't a Porsche dealer? My advice, find a shop that knows what they're doing and specialize or at least work regularly on Porsches. I believe the proper next steps would be to drop the sump plate, and bore scope the cylinders from the bottom to check for scoring.

The symptoms presented seem to point to bore scoring. - loud ticking sound - sooty pipes - excessive use of oil, more than the manual indicated

Thanks for the very quick responses. Sorry I am in the wrong forum. I am thinking scored bored, and plan to have it inspected at a local specialist. It�s my first Porsche so not a great choice. The car is still at the dealers so Not sure if I should try to get it fixed or a refund. I had the car a week and a half ehdn the ticking started.

You may be able to see the problem with an endoscope attached to your phone/laptop.Search for more. Does the car have a cold climate history?

Hey there Bikerdiverman, I'll be the parrot and repeat that these are classic symptoms of bore scoring, which is an issue we read about frequently on Rennlist. So I'm sorry to say, yes, you should be concerned. I'm not sure if this is good or bad news but you did JUST buy the car. Depending on what kind of consumer protections you have where you live - if you have the option to return the car I would strongly urge you to do so. Bore scoring is not something that happens spontaneously. So while it is certainly a possibility that you are just very unlucky and are the first person to notice symptoms, based on the fact this is a recent sale I am presuming that the previous owner was aware of this. The dealership that sold it to you potentially was not. It really depends on, in your judgment, how knowledgeable they are about Porsche cars and their quirks. They are saying they can't find fault so they are either being coy or genuinely do not understand what they are looking at. Both are bad - so if the garage that sold it to you won't take it back, refusing to recognize the issue, find a specialist that can provide you with the data you need to back your request for refund. If they are just an unethical seller and will play the "as is" card - we'll fill you in with your options at that point. Best of luck.

Mine did this, and it was not bore score, oh no much worse, it was thrust bearing failure. Pull the oil filter and see of its full of metal, if not then back to bore score, there are a couple of guys running them to the death, eventually its more of a 2 stroke with lots of oil consumption and perhaps a horrible death, otherwise time to call L&N.......

If they will take it back, do that and find another.
