Porsche 911 G-Modell from 1973-1989
Even though the body has been hot-dip galvanized since model year 76 (fully galvanized from model year 81), rust damage is also possible on the models. The zinc coating ages in those areas where high bending forces stress the sheet metal or where constant humidity prevails. This occurs in the Targa body, which is somewhat softer than the Coupé, especially in the area of the sills. Repairs are also not always carried out with galvanized sheet metal.
This is why rust nests are also possible on the Porsche 911 G model: A and B pillars with entry plates, front fenders, traverse between the front wishbones and front and rear axle mounts.
The 3.2-liter engines are particularly stable and mature. The typical stud bolt and chain tensioner problems hardly occur here anymore. Oil leakages at the connections of the housing halves, chain boxes are rather conceivable.
The 2.7-liter engines, on the other hand, are considered less trouble-free and, therefore, very extensive, even when the engine is overhauled.
