The salesman claimed the dealer installed a new 997 engine under warranty.
Leading evidence: 'Install 997 engine' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'same as the 3.6 997' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Install 997 engine' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Suspected cause
The seals are updated, it uses torx bolts instead of hex heads, and the manufacturing processes and materials are the latest, and the engine case is probably the same as the 3.6 997, but that is where the similarities end.

What are the pros and cons of replacing the 996 engine with a 997 engine?
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

I was out shopping for a �02 996 today and found a perfect low mileage C2 with less than 5000 miles on a new engine. According to the salesman the previous owner negotiated a new engine when the RMS blew. The salesman claimed the dealer installed a new 997 engine under warranty. He indicated the 997 engine is better designed and maybe a bit lighter. Is the 997 engine better? What are the pros and cons of replacing the 996 engine with a 997 engine? Thanks.
I wouldn't believe ANYTHING a car salesman told me. I'm sure there are enough differences between the two engines that this would be a very challenging upgrade, I could be wrong but I doubt it.
If the car had an engine swap because of the RMS, the replacement engine has many of the engineering improvements from the 997 program, but it is not a 997 engine.
I had the same thoughts about my 996 replacement engine because its S/N said that it was manufactured in 2005, but it is really a 996 engine.
The seals are updated, it uses torx bolts instead of hex heads, and the manufacturing processes and materials are the latest, and the engine case is probably the same as the 3.6 997, but that is where the similarities end.
Here is a 2005 996 engine, which is what the car in question probably has.
OE, that engine looks awesome.
By the way, after reading about how difficult putting a 3.6 into a 3.4 car, I can't even imagine how you cram a 997 engine in there. Doubtful as all can be.
Thanks for quick responses. I guess the previous owner could have been told that the new engine had the 997 �improvements� which may have been interpreted as a 997 engine. The dealer is local so I will give them a call and try to get some specifics. Based on some of the responses it sounds like we are talking about a round peg in a square hole. Is the engine that different?
