WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2019 Porsche 911, 2018 Porsche 911, 2017 Porsche 911, 2016 Porsche 911, and 2015 Porsche 911. However, it is still accessible from the selected car via links, so may be relevant.
- The engine must be at operating temperature in order to carry out the pressure loss test.
Information
- In the case of new engines that have not yet been fully run in (less than 5, 000 km), there may be higher pressure losses than after the run-in period as cylinders, pistons and piston rings have not yet attained their final dimensional stability.
- Differences between the individual cylinders of up to two graduation lines = 4 % pressure loss are not significant.
