Guess I will er on the side of caution and keep the lead out of the right foot for a while.
As to the reson for the failure at 27000kms. I was told the "jack shaft " bearing failed and cracked the housing which is why I dumped about 8l. of oil onto the road! Which begs the question what is the jack shaft?

Hi,

It's a little disturbing if your engine number is sequential. This is because Porsche has built only 160,000 Boxsters in total since '96.

If your engine # is sequential, it would suggest that they have produced some 40,000+ engines than they have actual cars, and that's just through '03. It would indicate an excess of about 130,000 engines in all.

I hope they weren't anticipating the need for these as it would indicate about a 25% failure rate. Wouldn't you love to know what they know, but we don't...and they're not telling...??

Hi, Jim 99,
I think I may have confused with the #'s I quoted.
The original eng.# was 65305353 in a Jan.03 build however, the replacement eng.# is 65465750 and was put in 3 weeks ago. I'm assuming the numbers run sequentually for each engine size therefore 160397 engines have been built between these dates.
Does this tally with your thinking?
Cheers,
Glenn

All this 03 engine replacement talk is making me nervous! Maybe it's just me but it seems like I hardly ever see or hear of the 3.2L's failing compared to the 2.7L's. I know the pool of 2.7's floating around out there is larger, but it makes me wonder. I wish we had access to some hard statistics!
