Default Is this a dealbreaker?

I am looking to buy a 2003 911 TT. I found one that has 20,000 miles on it and it’s very clean. The test drive went well with no indications of a misfire or low performance. However, one of the documents the seller had discusses the number of over revs in range 2. Also, all of the plugs were replaced a month before this service and it appears plug five was replaced again. I am having a PPI completed tomorrow and passed https://www.cars.com/vehicledetail/d...t&CMP=atempeston the service record to mechanic. would this scare you off ? i

Overrevs are blown out of proportion IMO.

How many and how long ago? By using the hours and average info from a durametric report it should tell you how long it’s been since the overrev and you can see if it corresponds with any of the service info.

Concur with Jferrante. I would be more concerned about why that cylinder 5 spark plug was damaged and the vacuum line disconnected.

I agree that the damaged plug is the greater concern. Could the disconnected vacuum line and a high rev pull cause a plug to go bad or was the mechanic just not taking any chances and just replaced the plug due to the misfire? I see that the leak down test notes good cylinder pressures which is positive. Anyone have a suggestion on what the PPI mechanic should at to confirm there is no chronic concerns?

car needs to be driven another 6 hours to see if it was damaged during over rev 4 hours ago, and to see if the codes come back.

mmmmmmmm ..... Not the first time we have seen very recent over-revs on dealer cars. Too many employees & relatives have access. As noted, now you should put more operating hours between the event & the now.

For that price and the potential issues/risks, I would walk away. For that price you should be able to find turbo S

Agree with Turbodan, I personally don't feel confortable with an overevs type 2 that happen just recently. Somebody was having too much fun and really push the limit of this car or miss a shift. Why take the chance, there are so many for sale....

For reference I pulled my overrevs with my Durametric the other day...tens of thousands Type 2s and my car is what I consider babied - it also has a slightly increased rev limit which means its an instant type 2 everytime there's an ignition close to its current redline. You need to look at the specific situation for the car. Overrevs in a 996 are not nearly as informative as in the newer cars.

Overblown, but yes, figure out what the issue with the plug is.

If the car has the stock redline, I would absolutely walk away from that many Range 2's that recently.

I agree that Range 2's are generally overblown, but this is exactly the kind of example that should actually be worrisome.

7250 RPM / 60 * 3 ignitions per revolution= 362.5 ignitions per second

1227 / 362.5 = ~3.4s

If the car isn't chipped, that looks like a misshift happened at some point in the car's life -- was it 4 hours ago or 400? Who knows?

Calculation is good but it can also be an addition of many type 2, that we don't know......

OT but I was batting around the idea of a 996Gt3 recently and found one that was owned by a known track rat. Car seemed great and they were promoting it as having a great over rev report.

0 Type 1
0 Type 2.

Thats the car you you need to worry about!!!!
