I went for a long drive tonight. On the way back I noticed a slight
noise that the motor hadn't made before -- after putting at load for
a while, it would make a knocking sound when I backed off the throttle.
When I pulled into my driveway, I noticed that it was making a much
louder knocking noise at idle. The noise would go away if I blipped
the throttle, and didn't seem to speed up much when I blipped the
throttle, but it did come back (louder) after I backed off.
The noise seemed to be coming from near the rear of the motor. It
continued to idle smoothly and the motor didn't jump around, but
it did start to stall more and more easily. I checked and the oil
light and it was not on or flickering or anything. I shut the motor
down and restarted it and the oil lamp behaved as normal, but the
car quickly stalled and I did not restart it.
The car was running well, had normal temp and oil pressure and was
getting good mileage and made lots of power when it did this. Guess
I don't need to worry about the amsoil for a while.
Where should I start, besides looking at all the plugs and listening
around with some vacuum hose in my ear... Timing gear? spun cam
bearing? broken connecting rod / crank bearing?
