Porsche to replace engines in every recalled 911 GT3by Justin King
Connecting-rod fasteners said to be prone to failure, causing recent fires.
Porsche has reportedly confirmed that it plans to replace the engine in every 911 GT3 that was built for the 2014 model year.
In a letter allegedly sent to a 911 GT3 owner, the company noted that its investigation has settled on a defective connecting-rod fastener, which is prone to loosening and consequently damaged the crankcase in two cars that caught fire in Europe.
"In order to avoid this in the future, an optimized screw connection is currently being tested," the company wrote in the letter, which was posted by Autoweek. "For the final validation of this solution, Porsche AG is currently carrying out extensive tests."
Rather than continuing to use the "Mezger" engine of the 2013 model, Porsche adopted the 911 Carrera S powerplant for the latest GT3. Retuning and component upgrades squeeze 475 horsepower and 324 lb-ft of torque out of the mill.
"At Porsche we are rigorous when implementing an engineering solution, therefore, after the successful testing and validation we will be installing new engines with optimized piston rod screw connections in all 2014 Porsche 911 GT3 vehicles," the letter continues.
The company has promised to provide an update within three weeks, however a schedule for carrying out the engine replacement has yet to be announced.
