Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

6 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

Planet-9: 1 discussions

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

1 acknowledgements have no verified action link; they do not establish a repair result.

Outcome without a verified action link
It took some time to diagnose, hence the work performed, but they finally narrowed it down to that being the issue and then had it resolved.

POST 1Original post

Greetings Plaent-9 community, Im looking at a 2014 991.1 S being sold by a non- Porsche dealership and it has the following entry in the carfax at 3200 miles: Work performed at Porsche dealership Maintenance inspection completed Air filter replaced Battery serviced Camshaft(s) replaced/repaired Antifreeze/coolant flushed/changed Cylinder head gasket(s) replaced Engine removed to complete repair Oil and filter changed Ignition coil(s) replaced Engine/powertrain computer/module checked Tire condition and pressure checked Vehicle washed/detailed Computer(s) checked Engine compression checked A/C refrigerant recharged Spark plug(s) replaced I contacted my local Porsche dealership to see what they knew and was informed: This event (early on in its life) was found to be a broken valve spring on cylinder #2. It took some time to diagnose, hence the work performed, but they finally narrowed it down to that being the issue and then had it resolved. Here are some photos. He did provide 2 photos of the broken spring. The car now has 18500 miles so a tad over 15k since this happened and concerned that perhaps not enough miles have been driven since. Im a newerish Porsche owner and would appreciate feedback from those willing to provide it. Thanks in advance. gut

POST 2Original post

15k miles should be plenty to identify any other major problems. If you like the car, get a PPI and go for it.

POST 3Original post

%^#$ Carfax. I'm sure mine indicates the car has never been cared for, I have a box of receipts to the contrary. Also, if you were in certain kinds of accidents not involving another vehicle and paid your buddy the body-man in cold hard cash Carfax would never know.

POST 4Original post

Appreciate the feedback. Over the past day or so I found myself lucky enough to get the opportunity to purchase a very similar 991.1 with nearly half the miles and a 2yr CPO for basically the same price as this car. Very excited!

POST 5Original post

Congratulations on a great buy! Jack
