Porsche does indeed get it wrong sometimes and they had a major problem with the 991 GT3 when they had a couple of engine fires, caused by the conrod bolts letting go. There was something about the bolts - the material, the thread, the tightening torque - which caused them to let go. Lots of loose metal in the engine, fractured crankcase, oil leak and fire.
They could not predict which engines would fail so they pulled all 850 cars made to date off the road, suspended production and owners got £5k + £50 a day compensation and a free loan of a new or nearly new 911. One person I know put 6k miles on the loaner, including some track days with all the cosmetic implications of doing that.
They replaced the engine in every car; mine was done before I bought it and came with an engine change certificate.
The new engine came complete on a palette with no swapping of parts over to minimise the work installing it. The dealers also got, it's said, an invoice for £62k for the new engine which was only credited when the old engine made it back to Porsche, presumably to prevent the old engines finding their way into the wild.
Great car though and when I rev it to 9000 rpm, I think of the forces on those bolts and hope they got it right second time. Mark
