Ok,
So my 73 was running great until it slowly started to go down hill. Car would not start after it was running/driving for a while but the next day would fire right up. Recenltly changed the oil that was completly diluted with gasoline. WTF?? |

Gas has washed past the rings and into the sump. Good thing you changed it; gasoline does not lubricate like oil does. This happens any time the mixture is rich enough that the engine almost doesn't run.
Things to check: Fuel pressure, disconnected wires (especially head temp sensor wire), MPS that won't hold vacuum, unplugged hoses... --DD |
