1983 911SC Vacuum Hose Placement


Vehicle Information: Model: 911; Year: 1983; Body Type: Targa; Total Mileage: 5000 ;

I bought the car with 500 miles on the motor. Motor did not run like I thought it should. Took it back to the builder and finally found that the vacuum lines going to the distributor were reversed. Car ran amazingly well, low and top end power was great. I had a major oil leak at the top of the motor that would coat the heater blower. They could not find it, so I dropped the motor myself, replaced the blower cover gasket, oil temperature sending unit and all hoses related to oil on top of the motor. I re-installed the motor. It ran great. I waited for new CV's, so I did not start it for a couple of weeks. As soon as I started it seemed to run on only 5 cylinders. To make a long story short, when I removed the intake to replace the blower gasket, I dropped a small washer into number 6. The engine builder took the valve cover off to reveal a broken rocker. He replaced the valves and reground the valve seats. Cylinder was not harmed. After cams were reinstalled, he found that they were initially timed incorrectly. Left side was set at .9 and the right at 1.2. He set both to spec at 1.55. The engine was re-installed, but it acted like it did when the vacuum lines were reversed, but when we switch them the engine starves and wants to die. The engine builder knows his stuff, but he seems to be stuck on this one. If I have to go to the dealer I will, but I would appreciate you input. Sorry for such a lengthy explanation, but I thought it was necessary.
