Very unlikely that they had any new 2.5s in inventory when they replaced the engine in '03.

The dealers invoice dated 7/25/03 shows they did replace the motor under warranty so maybe the previous owner had an extended warranty?

Was this a new motor or a rebuilt motor and do dealers change the odometer on the car to reflect the true miles on the engine?

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.

POST 1 / ORIGINAL POSTEROriginal post

Help! I purchased a 1999 Boxster and with the previous owners permission was able to get the service history from the dealer. I found out that in 2003 the motor seized and was replaced. The old # was M962065X11458. The new motor # is M962065X60102. Can anyone explain what these numbers mean? Was this a new motor or a rebuilt motor and do dealers change the odometer on the car to reflect the true miles on the engine? Thank you.

POST 2Original post

This is my stab at it; since your '99 engine seized in '03, I'm guessing it was out of warranty. The engine that replaced it was more than likely re-manufactured, and that engine is the 48,644 engine (60102-11458=48644) to roll off the assembly line...again not necessarily a new one but rebuilt. The odometer doesn't show mileage on the engine (you would actually need an hour meter for that), it shows the mileage on the car. P.S. The cars computer records engine revolutions and over-rev events. There is a chance that the dealer was able to go in and "zero out" that parameter. If anyone knows if this is possible, ring in.

POST 3Original post

Adding to Jaxonalden's comments- Very unlikely that they had any new 2.5s in inventory when they replaced the engine in '03. In these cars, unless you're a collector, a replacement engine isn't a big deal. There've been alot of reasons to replace the engine over the years.

POST 4 / ORIGINAL POSTEROriginal post

Thanks for your reply. The dealers invoice dated 7/25/03 shows they did replace the motor under warranty so maybe the previous owner had an extended warranty? It has the statement "one time goodwill" under the labor and parts section of the invoice.

POST 5Original post

I'm surprised it said "One time goodwill" under warranty, isn't that what a warranty is all about? One time goodwill or good "deal", typical way they're standing behind their product...even one they warranty, shameless.
