911 motor
When I bought the car it had a rebuilt that had been left to sit due to fuel injection issues. A rebuilt motor that has been left to sit for years is no longer a rebuilt motor, it is a leaky old motor with good compression.
I systematically went through diagnosing problem after problem until I discovered that the car had developed rust in the gas tank from sitting. I then chased problem after problem that the rust had caused. The CIS system is very sensitive to rust particles clogging it up so just about everything was ruined. After resolving that I also discovered that the engine ran hot. It was a 2.7 with no external cooler. Clearly Porsche was not thinking on that one. I also discovered, in my search for help, that the shop that rebuilt my motor knows NOTHING about CIS. That was the reason that after the rebuild it would not run. Regardless, once all was sorted out, it ran strong but leaked oil everywhere and may not have been put together right by the shop. It was a definite factor in the decision to sell the car.
