Fix My Porsche! A Brief History of Porsche Models and Their Special Mechanical Concerns
Porsches are great cars, but they require special care. For instance, the Porsche 911s from the 1960s up until the late 1990s featured engines cooled buy air and circulating oil. Competition from Ferrari pushed the company to switch to liquid cool engines, which offer better performance and less noise. Some enthusiasts still prefer the air cooled models and that’s why vintage Porsches tend to be so popular. They like the feel of the engine and prefer the more hot rod sound. Yet mechanical problems still happen. We’re constantly having Porsche fans with a vintage car calling our Cincinnati shop and saying, “Hey, when can you fix my Porsche?”
Porsche 911s feature flat 6 cylinder engines, which explains their robust power and sturdy performance. The 912, sold until 1969, did have a 4 cylinder engine, but they tend to suffer from a lackluster performance.
The 964 Porsche is the third generation of 911s, and featured a bold new body with smoother bumpers and better designed aerodynamics, which really helps its performance and fuel efficiency. They also were some of the first cars to benefit from power steering and antilock brakes.
A Truly Timeless Automobile
The 911s are well designed and built to last. In fact, by most estimates, roughly 70 percent of all Porsches ever built are still on the road, if not a museum. Yet every model has its mechanical issues, so do your research. Like any car, you’ll still be calling your mechanic, saying, “When can I get my Porsche in to be fixed?”
Common Problems with Porsche Repair
What are the most common repair problems our Porsche technicians see? Oil leaks are pretty common for a number different Porsches, often involving valve cover gaskets and spark plug seals. The most damaging leaks come from the rear main seal, which usually shows in the center of the engine trans area. It can pretty much eat up your clutch if you don’t catch it in time. If you’re storing the car, check it for leaks. Leaks need the heat of driving to form a seal, and tend to loosen when the car is left to sit.
