If there had been a coolant leak under warranty Porsche would have fixed the leak. If there is a coolant leak after the warranty has expired, Porsche isn't obligated to fix it for free.

My approach to the coolant pipes is when the engine needs to be removed for other work, or a coolant pipe leaks and the engine has to be removed to fix it, I'll likely pin the lines at that time. If the engine doesn't have to be pulled before I assume room temperature, the coolant lines won't be pinned on my watch.

It will prevent them from popping out and the most inopportune time. $3k was the labor to re and re the motor and gearbox; at the same time, added new injectors, a new water pump, voltage regulator, oil, filter etc., so $3k for all that work is a relative bargain compared to being stranded on the side of the road completely buggered.

I may have mentioned this before, but if not, I am deathly afraid of airplanes, and as such, avoid flying at all but the most critical of cases. There isn't anywhere I cannot drive to in western Canada, or the western States that I cannot not get to in 48 hours or less, so I turn a lot of miles on the road, approximately 1.2 million over the last 21 years. Over that time, I have suffered some fairly incredible failures ranging from lost engines to transmissions, to water pumps, electronics, etc etc.

My point is that I intend to drive the turbo to Calgary and down to see my in laws in the interior during the three weeks of summer we get. An average rip will be 2400 - 2600kms, of sustained, 'spirited' driving through the mountains. As I was aware of this coolant line failure potential, what kind of idiot would I be to not try and mitigate that failure up front?

As I said, cheap insurance.

Exactly - needed the clutch, so do everything.

Hopefully, room temperature remains toasty.

The Vette has cheap build quality.

I think the engineering somewhat speaks for itself in the two pics; a lot more love has gone into the Porsche design than the Corvette.

As far as the coolant lines are concerned, even engineers are known to screw up the works, from time to time...

Buy a Corvette (if you don't already have one).

It wasn't the Porsche engineers in this case. The NHTSA had this as part of their findings (my bold):

"Porsche identified a manufacturing quality issue with the supplier's application of adhesive to coolant pipe fittings that resulted in elevated failure rates in approximately 6,800 early production 997 generation vehicles (MY 2007 and early MY 2008). ODI's analysis of field data showed that the age-adjusted failure rate for these vehicles was approximately six times greater than MY 2001 through 2005 996 generation vehicles and MY 2008 through 2011 997 generation vehicles built after a process improvement for adhesive application was implemented by the supplier."

I had a zo6. What's your point in comparing the two? they are as different as they are similar, both good cars in their own right. 996 build quality isn't the best.

See post #55 here in this thread.

I saw. Seems pointless comparing door hinges; hence post # 70.

If you saw then why did you ask?

Interesting how the passage of time puts it squarely on the 997 guys... I suppose in this case, hindsight was 20/20...
