I was thinking about Big Car the other day and a thought crossed my mind. The fuel injection pump is driven by the timing belt – that’s how it knows when to squirt the fuel. When we took the fuel injection pump off, the timing belt would have gone slack. The timing would have gotten all messed up when the engine was turned. I figured this could be why the inlet was blowing instead of sucking.
Today, I took the fan, water pump, fan belt, big nut and the timing cover off to get at the timing belt. I set up the timing and put it all back together again. When we turned the engine over we could get it to fire, but not on all cylinders. Also, the inlet was still blowing and there was an ominous knocking noise. I’m thinking that one of the inlet valves may be broken and that the head needs to come off…
