Porsche M96/M97 vs 1.2 8v: which engine is more reliable?
According to our risk index, the 1.2 8v carries less risk than the Porsche M96/M97: 36/100 (moderate risk) versus 50/100 (high risk). The Porsche M96/M97 has 4 documented serious faults, the main one being «Failure of the intermediate shaft bearing (IMS) on the M96/M97»; the 1.2 8v has 1 documented serious fault, the main one being «Damaged cylinder head gasket (coolant loss and overheating)».
The index (0–100) weights the severity and frequency of the three most serious documented faults. How it is calculated
Is the Porsche M96/M97 reliable?
It depends on the version: the M96/M97 has a reputation as a fragile engine because of the IMS bearing, scored cylinders and the rear crankshaft seal, but sources disagree on how many fail and none gives a verified statistic. The most exposed are the 986 and 996 from 1999-2005; the 997.2 and 987.2 from 2009 left this behind with the MA1 engine.[1][2][3][4]
See the 9 of the Porsche M96/M97 faultsIs the 1.2 8v reliable?
The 1.2 8v (D7F) is a simple naturally aspirated engine of 54 to 60 hp, with a timing belt, which Renault fitted from 1996 to the Twingo, Clio II and Kangoo. No catastrophic failures are documented; what owner reviews mention most often are the sensors, the cylinder head gasket, the coil packs and the occasional oil drip.[5][6][7]
