Is the Porsche MA1 / 9A1 reliable?

Yes, it is noticeably more reliable than the M96/M97: it eliminated the intermediate shaft with its IMS bearing and, according to FCP Euro, the connecting rod bolt failures. What is documented is minor: carbon build-up on the intake valves caused by direct injection, coolant pump leaks on the 991.1 and, rarely, bore scoring on the 997.2.[1][2][3][4]

Is the 1.6 and 2.0 8v EA827 reliable?

Simple, naturally aspirated petrol engines that, according to the sources, last a long time with regular maintenance. Gebrauchtwagenberater describes the 8-valve 1.6 as old-fashioned but reliable, and the 102 hp 1.6 MPI as even more reliable than the 1.4 16v. Watch the timing belt with the water pump, coolant leaks, oil consumption (especially on the 2.0) and idle and sensor faults.[5][6][7][8]
