The Bridge Classic Cars restoration team have been working hard on getting this 1981 Porsche 911 back out on the road and running better than ever, with our technician Oscar heading up the charge with the help of our technician Andy.
To begin with, Oscar has had to clean and repin some of the wiring connectors along with replacing a broken O2 sensor plug so that the car is getting all of the correct information and readings once the engine is back in place. Whilst out of the car, the clutch and pressure plate was inspected and found to be worn and glazed so were replaced by the team as the assembly was taken apart.
Once all done, the engine and gearbox could be raised back into the car for the team to reconnet the various lines and tubework also driveshafts and suspension components. Once in place, our technician Andy began to rerun the systems and wiring back in place.
